| 1 | Anaerobic microbiologically influenced corrosion mechanisms interpreted using bioenergetics and bioelectrochemistry: A review显示文摘Microbiologically influenced corrosion(MIC) is a major cause of corrosion damages, facility failures, and financial losses, making MIC an important research topic. Due to complex microbiological activities and a lack of deep understanding of the interactions between biofilms and metal surfaces, MIC occurrences and mechanisms are difficult to predict and interpret. Many theories and mechanisms have been proposed to explain MIC. In this review, the mechanisms of MIC are discussed using bioenergetics, microbial respiration types, and biofilm extracellular electron transfer(EET). Two main MIC types, namely EET-MIC and metabolite MIC(M-MIC), are discussed. This brief review provides a state of the art insight into MIC mechanisms and it helps the diagnosis and prediction of occurrences of MIC under anaerobic conditions in the oil and gas industry. | Yingchao Li Dake Xu Changfeng Chen Xiaogang Li Ru Jia Dawei Zhang Wolfgang Sand Fuhui Wang Tingyue Cu | 2018 | Journal of Materials Science & Technology2018，34，10： | 43 |
| 2 | Toward a better understanding of microbiologically influenced corrosion caused by sulfate reducing bacteria显示文摘Sulfate reducing bacteria(SRB) are often the culprits of microbiologically influenced corrosion(MIC) in anoxic environments because sulfate is a ubiquitous oxidant. MIC of carbon steel caused by SRB is the most intensively investigated topic in MIC because of its practical importance. It is also because biogenic sulfides complicate mechanistic SRB MIC studies, making SRB MIC of carbon steel is a long-lasting topic that has generated considerable confusions. It is expedient to think that biogenic H_2S secreted by SRB acidifies the broth because it is an acid gas. However, this is not true because endogenous H_2S gets its H^+ from organic carbon oxidation and the fluid itself in the first place rather than an external source. Many people believe that biogenic H_2S is responsible for SRB MIC of carbon steel. However, in recent years,well designed mechanistic studies provided evidence that contradicts this misconception. Experimental data have shown that cathodic electron harvest by an SRB biofilm from elemental iron via extracellular electron transfer(EET) for energy production by SRB is the primary cause. It has been demonstrated that when a mature SRB biofilm is subjected to carbon source starvation, it switches to elemental iron as an electron source and becomes more corrosive. It is anticipated that manipulations of EET related genes will provide genetic-level evidence to support the biocathode theory in the future. This kind of new advances will likely lead to new gene probes or transcriptomics tools for detecting corrosive SRB strains that possess high EET capabilities. | Tingyue Gu Ru Jia Tuba Unsal Dake Xu | 2019 | Journal of Materials Science & Technology2019，35，4： | 28 |
| 3 | Buyang Huanwu Decoction fraction protects against cerebral ischemia/reperfusion injury by attenuating the inflammatory response and cellular apoptosis显示文摘Buyang Huanwu Decoction fraction extracted from Buyang Huanwu Decoction contains saponins of Astragalus, total paeony glycoside and safflower flavones. The aim of this study was to demonstrate the neuroprotective effect and mechanism of Buyang Huanwu Decoction fraction on ischemic injury both in vivo and in vitro. In vivo experiments showed that 50-200 mg/kg Buyang Huanwu Decoction fraction reduced infarct volume and pathological injury in ischemia/reperfusion rats, markedly inhibited expression of nuclear factor-κB and tumor necrosis factor-α and promoted nestin protein expression in brain tissue. Buyang Huanwu Decoction fraction (200 mg/kg) exhibited significant effects, which were similar to those of 100 mg/kg Ginkgo biloba extract. In vitro experimental results demonstrated that 10-100 mg/L Buyang Huanwu Decoction fraction significantly improved cell viability, decreased the release of lactate dehydrogenase and malondialdehyde levels, and inhibited the rate of apoptosis in HT22 cells following oxygen-glucose deprivation. Buyang Huanwu Decoction fraction (100 mg/L) exhibited significant effects, which were similar to those of 100 mg/L Ginkgo biloba extract. These findings suggest that Buyang Huanwu Decoction fraction may represent a novel, protective strategy against cerebral ischemia/reperfusion injury in rats and oxygen-glucose deprivation-induced damage in HT22 cells in vitro by attenuating the inflammatory response and cellular apoptosis. | Yulian Jin Liuyi Dong Changqing Wu Jiang Qin Sheng Li Chunyan Wang Xu Shao Dake Huang | 2013 | Neural Regeneration Research2013，8，3： | 11 |
| 4 | Microbiologically influenced corrosion behavior of S32654 super austenitic stainless steel in the presence of marine Pseudomonas aeruginosa biofilm显示文摘S32654 super austenitic stainless steel(SASS) is widely used in highly corrosive environments. However,its microbiologically influenced corrosion(MIC) behavior has not been reported yet. In this study, the corrosion behavior of S32654 SASS caused by a corrosive marine bacterium Pseudomonas aeruginosa was investigated using electrochemical measurements and surface analysis techniques. It was found that P. aeruginosa biofilm accelerated the corrosion rate of S325654 SASS, which was demonstrated by a negative shift of the open circuit potential(EOCP), a decrease of polarization resistance and an increase of corrosion current density in the culture medium. The largest pit depth of the coupons exposed in the P.aeruginosa broth for 14 days was 2.83 m, much deeper than that of the control(1.33 m) in the abiotic culture medium. It was likely that the P. aeruginosa biofilm catalyzed the formation of CrO_3, which was detrimental to the passive film, resulting in MIC pitting corrosion. | Huabing Li Chuntian Yang Enze Zhou Chunguang Yang Hao Feng Zhouhua Jiang Dake Xu Tingyue Gu Ke Yang | 2017 | Journal of Materials Science & Technology2017，33，12： | 10 |
| 5 | Antibacterial Performance of a Cu-bearing Stainless Steel against Microorganisms in Tap Water显示文摘Tap water is one of the most commonly used water resources in our daily life. However, the increasing water contamination and the health risk caused by pathogenic bacteria, such as Staphylococcus aureus and Escherichia coli have attracted more attention. The mutualism of different pathogenic bacteria may diminish antibacterial effect of antibacterial agents. It was found that materials used for making pipe and tap played one of the most important roles in promoting bacterial growth. This paper is to report the performance of an innovative type 304 Cu-bearing stainless steel(304Cu SS) against microbes in tap water. The investigation methodologies involved were means of heterotrophic plate count, contact angle measurements, scanning electron microscopy for observing the cell and subtract surface morphology,atomic absorption spectrometry for copper ions release study, and confocal laser scanning microscopy used for examining live/dead bacteria on normal 304 stainless steel and 304 Cu SS. It was found that the surface free energy varied after being immersed in tap water with polar component and Cu ions release.The results showed 304 Cu SS could effectively kill most of the planktonic bacteria(max 95.9% antibacterial rate), and consequently inhibit bacterial biofilms formation on the surface, contributing to the reduction of pathogenic risk to the surrounding environments. | Mingjun Li Li Nan Dake Xu Guogang Ren Ke Yang | 2015 | Journal of Materials Science & Technology2015，31，3： | 10 |
| 6 | Effect of nitrogen on corrosion behaviour of a novel high nitrogen medium-entropy alloy CrCoNiN manufactured by pressurized metallurgy显示文摘A novel high nitrogen medium-entropy alloy CrCoNiN, which had higher strength and slightly lower ductility than CrCoNi alloy, was successfully manufactured by pressurized metallurgy. The microstructure and corrosion behaviour were investigated by microscopic, electrochemical and spectroscopic methods.The results indicated that nitrogen existed in the form of Cr_2N precipitates and uniformly distributed N atoms, and nitrogen alloying significantly refined the grain size. Besides, nitrogen enriched on the outmost surface of passive film and metal/film interface as ammonia(NH-_3 and NH_4^+) and CrN, respectively. The significant improvement of corrosion resistance of CrCoNiN was attributed to the lower metastable pitting susceptibility together with thicker, less defective and more compact passive film. | Hao Feng Huabing Li Xiaolei Wu Zhouhua Jiang Si Zhao Tao Zhang Dake Xu Shucai Zhang Hongchun Zhu Binbin Zhang Muxin Yang | 2018 | Journal of Materials Science & Technology2018，34，10： | 8 |
| 7 | Microbiologically influenced corrosion of titanium caused by aerobic marine bacterium Pseudomonas aeruginosa显示文摘Microbiologically influenced corrosion(MIC) is a big threat to the strength and safety of many metallic materials used in different environments throughout the world. The metabolites and bioactivity of the microorganisms cause severe deterioration on the metals. In this study, MIC of pure titanium(Ti) was studied in the presence of a highly corrosive aerobic marine bacterium Pseudomonas aeruginosa. The results obtained from electrochemical test showed that Ti was corrosion resistant in the abiotic culture medium after 14 d, while the increased corrosion current density(i_(corr)) obtained from polarization curves and the decreased charge transfer resistance(R_(ct)) from electrochemical impedance spectroscopy(EIS)indicated the accelerated corrosion of Ti caused by P. aeruginosa biofilm. For further confirmation of the above results, the surface of Ti was investigated using scanning electron microscopy(SEM), confocal laser scanning microscopy(CLSM) and X-ray photoelectron spectroscopy(XPS). According to the XPS results, TiO_2 was formed in both abiotic and biotic conditions, while unstable oxide Ti_2O_3 was detected in the presence of P. aeruginosa, leading to the defects in the passive film and localized corrosion. Pitting corrosion was investigated with the help of CLSM, and the largest pit depth found on Ti surface immersed in P. aeruginosa was 1.2 μm. Ti was not immune to MIC caused by P. aeruginosa. | M.Saleem Khan Zhong Li Ke Yang Dake Xu Chunguang Yang Dan Liu Yassir Lekbach Enze Zhou Phuri Kalnaowakul | 2019 | Journal of Materials Science & Technology2019，35，1： | 8 |
| 8 | Microbial corrosion resistance of a novel Cu-bearing pipeline steel显示文摘Microbiologically influenced corrosion(MIC) is becoming a serious problem for buried pipelines. Developing environmentally friendly strategies for MIC control is increasingly urgent in oil/gas pipeline industry.Copper(Cu) in steels can not only provide aging precipitation strengthening, but also kill bacterium,offering a special biofunction to steels. Based on the chemical composition of traditional X80 pipeline steel, two Cu-bearing pipeline steels(1% Cu and 2% Cu) were fabricated in this study. The microstructure,mechanical properties and antibacterial property against sulphate-reducing bacteria(SRB) and Pseudomonas aeruginosa(P. aeruginosa) were studied. It was found that the novel pipeline steel alloyed by 1%Cu exhibited acicular ferrite microstructure with nano-sized Cu-rich precipitates distribution in the matrix, resulting in better mechanical properties than the traditional X80 steel, and showed good MIC resistance as well. The pitting corrosion resistance of 1% Cu steel in as-aged condition was significantly better than that of X80 steel. A possible antibacterial mechanism of the Cu-bearing pipeline steel was proposed. | Xianbo Shi Wei Yan Dake Xu Maocheng Yan Chunguang Yang Yiyin Shan Ke Yang | 2018 | Journal of Materials Science & Technology2018，34，12： | 7 |
| 9 | A novel Cu-bearing high-entropy alloy with significant antibacterial behavior against corrosive marine biofilms显示文摘The design of novel high-entropy alloys(HEAs)provides a unique opportunity for the development of structure-function integrated materials with high mechanical and antimicrobial properties.In this study,by employing the antibacterial effect of copper,a novel Al0.4CoCrCuFeNi HEA with broad-spectrum antibacterial and strong mechanical properties was designed.High concentrations of copper ions released from the HEA prevented growth and biofilm formation by biocorrosive marine bacterial species.These findings serve as a proof-of-concept for further development of unique HEA materials with high antimicrobial efficiency and mechanical properties,compared to conventional antibacterial alloys. | Enze Zhou Dongxu Qiao Yi Yang Dake Xu Yiping Lu Jianjun Wang Jessica A.Smith Huabing Li Hongliang Zhao Peter K.Liaw Fuhui Wang | 2020 | Journal of Materials Science & Technology2020，42，11： | 6 |
| 10 | Enhanced antibacterial behavior of a novel Cu-bearing high-entropy alloy显示文摘Contact infection of bacteria and viruses has been a critical threat to human health. The worldwideoutbreak of COVID-19 put forward urgent requirements for the research and development of the selfantibacterial materials, especially the antibacterial alloys. Based on the concept of high-entropy alloys, thepresent work designed and prepared a novel Co_(0.4)FeCr_(0.9)Cu_(0.3) antibacterial high-entropy alloy with superior antibacterial properties without intricate or rigorous annealing processes, which outperform the antibacterial stainless steels. The antibacterial tests presented a 99.97% antibacterial rate against Escherichiacoli and a 99.96% antibacterial rate against Staphylococcus aureus after 24 h. In contrast, the classic antibacterial copper-bearing stainless steel only performed the 71.50% and 80.84% antibacterial rate, respectively. The results of the reactive oxygen species analysis indicated that the copper ion release and theimmediate contact with copper-rich phase had a synergistic effect in enhancing antibacterial properties.Moreover, this alloy exhibited excellent corrosion resistance when compared with the classic antibacterialstainless steels, and the compression test indicated the yield strength of the alloy was 1015 MPa. Thesefindings generate fresh insights into guiding the designs of structure-function-integrated antibacterial alloys. | Guangyu Ren Lili Huang Kunling Hu Tianxin Li Yiping Lu Dongxu Qiao Haitao Zhang Dake Xu Tongmin Wang Tingju Li Peter K.Liaw | 2022 | Journal of Materials Science & Technology2022，，22： | 6 |
| 11 | Methanogenic archaea and sulfate reducing bacteria induce severe corrosion of steel pipelines after hydrostatic testing显示文摘Complex interactions within a microbial consortium can induce severe corrosion in oil pipelines.This study investigated the mechanism of microbiologically influenced corrosion(MIC)that led to failure of X52 steel pipelines after hydrostatic testing.Laboratory hydrostatic testing with untreated lake water and underground water were used to simulate and study the events that led to the actual corrosion.Biofilm analysis,weight loss,and several electrochemical measurements demonstrated rapid corrosion rates after hydrostatic testing.Analysis of microbial community structures revealed that methanogenic archaea and sulfate reducing bacteria(SRB),introduced by the hydrotest water,formed corrosive biofilms on X52 steel coupon surfaces that induced severe pitting. | Enze Zhou Jianjun Wang Masoumeh Moradi Huabing Li Dake Xu Yuntian Lou Jinheng Luo Lifeng Li Yulei Wang Zhenguo Yang Fuhui Wang Jessica A.Smith | 2020 | Journal of Materials Science & Technology2020，47，13： | 5 |
| 12 | Effects of surface waves and sea spray on air–sea fluxes during the passage of Typhoon Hagupit显示文摘Air–sea exchange plays a vital role in the development and maintenance of tropical cyclones(TCs). Although studies have suggested the dependence of air–sea fluxes on surface waves and sea spray, how these processes modify those fluxes under TC conditions have not been sufficiently investigated based on in-situ observations.Using continuous meteorological and surface wave data from a moored buoy in the northern South China Sea,this study examines the effects of surface waves and sea spray on air–sea fluxes during the passage of Typhoon Hagupit. The mooring was within about 40 km of the center of Hagupit. Surface waves could increase momentum flux to the ocean by about 15%, and sea spray enhanced both sensible and latent heat fluxes to the atmosphere,causing Hagupit to absorb 500 W/m^2 more heat flux from the ocean. These results have powerful implications for understanding TC–ocean interaction and improving TC intensity forecasting. | HE Hailun WU Qiaoyan CHEN Dake SUN Jia LIANG Chujin JIN Weifang XU Yao | 2018 | Acta Oceanologica Sinica2018，37，5： | 5 |
| 13 | Effect of Cu Addition to 2205 Duplex Stainless Steel on the Resistance against Pitting Corrosion by the Pseudomonas aeruginosa Biofilm显示文摘The effect of copper addition to 2205 duplex stainless steel(DSS) on its resistance against pitting corrosion by the Pseudomonas aeruginosa biofilm was investigated using electrochemical and surface analysis techniques. Cu addition decreased the general corrosion resistance, resulting in a higher general corrosion rate in the sterile medium. Because DSS usually has a very small general corrosion rate, its pitting corrosion resistance is far more important. In this work, it was shown that 2205-3%Cu DSS exhibited a much higher pitting corrosion resistance against the P. aeruginosa biofilm compared with the 2205 DSS control, characterized by no significant change in the pitting potential and critical pitting temperature(CPT) values. The strong pitting resistance ability of 2205-3%Cu DSS could be attributed to the copper-rich phases on the surface and the release of copper ions, providing a strong antibacterial ability that inhibited the attachment and growth of the corrosive P. aeruginosa biofilm. | Ping Li Yang Zhao Yuzhi Liu Ying Zhao Dake Xu Chunguang Yang Tao Zhang Tingyue Gu Ke Yang | 2017 | Journal of Materials Science & Technology2017，33，7： | 5 |
| 14 | Fabricating antibacterial CoCrCuFeNi high-entropy alloy via selective laser melting and in-situ alloying显示文摘A quasi-equiatomic CoCrFeCuNi high-entropy alloy(HEA) with a broad-spectrum antibacterial ability and good mechanical properties has been fabricated by selective laser melting(SLM) and in-situ alloying of a blend of pre-alloyed CoCrFeNi powder and Cu elemental powder.The as-built HEA alloy has a homogeneous distribution of Cu and presents a single FCC phase.Compared with the same HEA fabricated using the traditional ingot metallurgy(IM) process,the HEA alloy fabricated by SLM releases more Cu ions to prevent growth and biofilm formation by gram-negative Escherichia coli and gram-positive Staphylococcus aureus,which enhances the applicability of the HEA alloy in potential applications that requires antibacterial ability.The results of this study confirm the feasibility of combining the antibacterial CoCrFeCuNi HEA alloy and SLM technology in fabricating complex shaped parts or structures with a strong antibacterial ability to be used in medical application or other environments desired for antibacterial ability. | Jingbo Gao Yuting Jin Yongqiang Fan Dake Xu Lei Meng Cong Wang Yuanping Yu Deliang Zhang Fuhui Wang | 2022 | Journal of Materials Science & Technology2022，，7： | 4 |
| 15 | Enhanced resistance of 2205 Cu-bearing duplex stainless steel towards microbiologically influenced corrosion by marine aerobic Pseudomonas aeruginosa biofilms显示文摘An antibacterial 2205-Cu duplex stainless steel(DSS)was shown to inhibit the formation and growth of corrosive marine biofilms by direct contact with copper-rich phases and the release of Cu^(2+)ions from the2205-Cu DSS surface.In this work,the microbiologically influenced corrosion(MIC)resistance of 2205-Cu DSS in the presence of the corrosive marine bacterium Pseudomonas aeruginosa was investigated.The addition of copper improved the mechanical properties such as the yield strength,the tensile strength and the hardness of 2205 DSS.Electrochemical test results from linear polarization resistance(LPR),electrochemical impedance spectroscopy(EIS)and critical pitting temperature(CPT)measurements showed that 2205-Cu DSS possessed a larger polarization resistance(R_p),charge transfer resistance(R_(ct))and CPT values,indicating the excellent MIC resistance of 2205-Cu DSS against the corrosive P.aeruginosa biofilm.The live/dead staining results and the SEM images of biofilm confirmed the strong antibacterial ability of 2205-Cu DSS.The largest pit depth of 2205-Cu DSS was considerably smaller than that of 2205 DSS after 14 d in the presence of P.aeruginosa(2.2μm vs 12.5μm).2205-Cu DSS possessed a superior MIC resistance to regular 2205 DSS in the presence of aerobic P.aeruginosa. | Dake Xu Enze Zhou Ying Zhao Huabing Li Zhiyong Liu Dawei Zhang Chunguang Yang Hai Lin Xiaogang Li Ke Yang | 2018 | Journal of Materials Science & Technology2018，34，8： | 4 |
| 16 | Effect of organic silicon quaternary ammonium salts on mitigating corrosion of reinforced steel induced by SRB in mild alkaline simulated concrete pore solution显示文摘The corrosion damage of 20 SiMn steel by sulphate-reducing bacteria(SRB)and the mitigation effect of organic silicon quaternary ammonium salt(OSA)were studied in sterilized mild alkaline simulated concrete pore solution(STR)with different additions of SRB and OSA at pH 9.35 for 28 days.Uniform corrosion occurs in STR medium while slight localized corrosion is observed in STR+OSA medium,and localized pitting corrosion occurs in STR+SRB and STR+SRB+OSA media.The largest pit depth reduces from 36.70μm in STR+SRB medium to 3.31μm in STR+SRB+OSA medium due to the mitigation effect of OSA.The corrosion rate reflected by weight loss and electrochemical impedance spectroscopy(EIS)results presents the order of STR | Ini-Ibehe Nabuk Etim Junhua Dong Jie Wei Chen Nan Durga Bhakt Pokharel Aniefiok Joseph Umoh Dake Xu Mingzhong Su Wei Ke | 2021 | Journal of Materials Science & Technology2021，，5： | 3 |
| 17 | Applicability of the Welch method for examining self-noise level parameters for broadband seismometers显示文摘Seismometer self-noise levels were determined using Sleeman's three-sensor method in combination with the Welch method for different parameter combinations. The self-noise levels decreased with the increasing segment window length, which is equivalent to the subwindow length, and with the increasing segment overlap rate for different frequency points at a fixed band. After the statistical examination of 9800 different parameter combinations, a zone of reasonable self-noise calculation parameter combinations was identified. Reasons for the unsuitability of certain parameter combinations were explored with respect to their distortion of the seismometer's self-noise levels. | Li Xiaojun Yang Dake Xie Jianbo Ma Jiemei Yuan Songyong Xu Weiwei Zhao Jianhe Li Dongsheng | 2015 | Geodesy and Geodynamics2015，6，3： | 3 |
| 18 | Review on the corrosion-promotion activity of graphene and its inhibition显示文摘Graphene films(GFs) and graphene-reinforced nanocomposite coatings(GNCs) have received unprecedented attention for corrosion protection because graphene possesses a remarkable chemical inertness and is completely impermeable to aggressive chemicals. However, the high electric conductivity and positive potential of graphene make graphene-based metal protectors tend to exhibit an undesirable high corrosion-promotion activity(CPA), which is widely known as the phenomenon that graphene connecting with metal accelerates the corrosion of metal substrate by inducing micro-galvanic corrosion at the defect sites of GFs or GNCs in aggressive environments. Therefore, inhibiting the CPA of graphene is currently a key focus for the application of graphene in the field of corrosion protection. In this review, the mechanisms, influencing factors, and inhibition strategies of the CPA of GFs and GNCs are highlighted from the point of view of corrosion science to address the bottlenecks and challenges for future research and potential applications of graphene for corrosion protection. | Wen Sun Yanjia Yang Zhengqing Yang Lida Wang Jing Wang Dake Xu Guichang Liu | 2021 | Journal of Materials Science & Technology2021，，32： | 2 |
| 19 | Microbial ingress and in vitro degradation enhanced by glucose on bioabsorbable Mg-Li-Ca alloy显示文摘Biodegradable magnesium alloys are challenging to be implanted in patients with hyperglycemia and diabetes.A hypothesis is suggested that glucose accelerates microbial ingress and in vitro degradation of Mg-Li-Ca implants.Corrosion resistance and mechanical properties was demonstrated using electrochemical,hydrogen evolution and tensile tests.The bacteria from Hank's solution were isolated via 16S rRNA gene analysis.The results revealed that Mg-1Li-1Ca alloy exhibited different responses to Hank's solution with and without glucose.The solution acidity was ascribed to Microbacterium hominis and Enterobacter xiangfangensis,indicating that glucose promoted microbial activity and degradation and deterioration in mechanical property of Mg-1Li-1Ca alloy. | Ling-Yu Li Zhuang-Zhuang Han Rong-Chang Zeng Wei-Chen Qi Xiao-Fan Zhai Yi Yang Yun-Tian Lou Tingyue Gu Dake Xu Ji-Zhou Duan | 2020 | Bioactive Materials2020，5，4： | 2 |
| 20 | Corrosion Inhibition of X80 Steel in Simulated Marine Environment with Marinobacter aquaeolei显示文摘In the present study, a novel bacterium( Marinobacter aquaeolei) was examined for its corrosion inhibiting behaviour against X80 pipeline steel. Electrochemical results showed that X80 steel immersed in the solution inoculated with M. aquaeolei possessed very high corrosion resistance compared to that of abiotic control. Besides, scanning electron microscopy, confocal laser scanning microscopy and energy-dispersive X-ray spectroscopy were employed to analyse the corrosion product and the biofi lm formed on the metal surface. Fourier-transform infrared spectroscopy was also applied to determine the composition of extracellular polymeric substances(EPS). Above results indicated that the corrosion inhibition effciency observed in biotic medium was very high(91%), proving that M. aquaeolei was an effective inhibitive agent for the corrosion of carbon steel. The inhibition was credited to the formation of bacterial biofi lm and the compact protective layer of the secreted EPS. Thus, this study will introduce a natural, environmentally friendly and cost-effective system for the corrosion control of the carbon steel. | M.Saleem Khan Dake Xu Dan Liu Yassir Lekbach Ke Yang Chunguang Yang | 2019 | Acta Metallurgica Sinica(English Letters)2019，32，11： | 2 |
