| 1 | Lignin Interaction with Cellulase during Enzymatic Hydrolysis显示文摘The conversion of lignocellulosic biomass into biofuels or biochemicals typically involves a pretreatment process followed by the enzyme-catalyzed hydrolysis of cellulose and hemicellulose components to fermentable sugars.Many factors can contribute to the recalcitrance of biomass,e.g.,the lignin content and structure,crystallinity of cellulose,degree of fiber polymerization,and hemicellulose content,among others.However,nonproductive binding between cellulase and lignin is the factor with the greatest impact on enzymatic hydrolysis.To reduce the nonproductive adsorption of enzymes on lignin and improve the efficiency of enzymatic hydrolysis,this review comprehensively summarized the progress that has been made in understanding the interactions between lignin and enzymes.Firstly,the effects of pretreatment techniques on lignin content and enzymatic hydrolysis were reviewed.The effects of lignin content and functional groups on enzymatic hydrolysis were then summarized.Methods for the preparation and characterization of lignin films were assessed.Finally,the methods applied to characterize the interactions between lignin and cellulase were reviewed,and methods for decreasing the nonproductive binding of enzymes to lignin were discussed.This review provides an overview of the current understanding of how lignin hinders the enzymatic hydrolysis of lignocellulosic biomass,and provides a theoretical basis for the development of more economical and effective methods and additives to reduce the interaction of lignin and enzymes to improve the efficiency of enzymatic hydrolysis. | Mingfu Li Qingtong Zhang Changzhou Chen Shuangfei Wang Douyong Min | 2019 | Paper And Biomaterials2019，4，4： | 12 |

| 3 | Cloning and expression analysis in mature individuals of two chicken type-Ⅱ GnRH (cGnRH-Ⅱ) genes in common carp (Cyprinus carpio)显示文摘Gonadotropin-releasing hormone (GnRH) is a conservative neurodecapeptide fam-ily, which plays a crucial role in regulating the gonad development and in controlling the final sexual maturation in vertebrate. Two differing cGnRH-II cDNAs of common carp, namely cGnRH-II cDNA1 and cDNA2, were firstly cloned from the brain by rapid amplification of cDNA end (RACE) and reverse transcription- polymerase chain reaction (RT-PCR). The length of cGnRH-II cDNA1 and cDNA2 was 622 and 578 base pairs (bp), respectively. The cGnRH-II pre-cursors encoded by two cDNAs consisted of 86 amino acids, including a signal peptide, cGnRH-II decapeptide and a GnRH-associated peptide (GAP) linked by a Gly-Lys-Arg proteolytic site. The results of intron trapping and Southern blot showed that two differing cGnRH-II genes in common carp genome were further identified, and that two genes might exist as a single copy. The multi-gene coding of common carp cGnRH-II gene offered novel evidence for gene duplica-tion hypothesis. Using semi-quantitative RT-PCR, expression and relative expression levels of cGnRH-II genes were detected in five dissected brain regions, pituitary and gonad of common carp. With the exception of no mRNA2 in ovary, two cGnRH-II genes could be expressed in all the detected tissues. However, expression levels showed an apparent difference in different brain regions, pituitary and gonad. According to the expression characterization of cGnRH-II genes in brain areas, it was presumed that cGnRH-II might mainly work as the neurotransmitter and neuromodulator and also operate in the regulation for the GnRH releasing. Then, the ex-pression of cGnRH-II genes in pituitary and gonad suggested that cGnRH-II might act as the autocrine or paracrine regulator. | LI Shuangfei HU Wei WANG Yaping ZHU Zuoyan | 2004 | Science China(Life Sciences)2004，47，4： | 8 |
| 4 | Identification of Rice QTLs for Important Agronomic Traits with Long-Kernel CSSL-Z741 and Three SSSLs显示文摘Rice kernel shape affects kernel quality(appearance) and yield(1000-kernel weight) and therefore is an important agronomic trait, but its inheritance is complicated. We identified a long-kernel rice chromosome segment substitution line(CSSL), Z741, derived from Nipponbare as a recipient and Xihui 18 as a donor parent. Z741 has six substitution segments distributed on rice chromosomes 3, 6, 7, 8 and 12 with an average replacement length of 5.82 Mb. Analysis of a secondary F2 population from a cross between Nipponbare and Z741 identified 20 QTLs for important agronomic traits. The kernel length of Z741 is controlled by a major QTL(qKL3) and a minor QTL(qKL7). Candidate gene prediction and sequencing indicated that qKL3 may be an allele of OsPPKL1, which encodes a protein phosphatase implicated in brassinosteroid signaling, and qKL7 is an unreported QTL. Finally, we validated eight QTLs(qKL3, qKL7, qRLW3-1, qRLW7, qPH3-1, qKWT3, qKWT7 and qNPB6) using three selected singlesegment substitution lines(SSSLs), S1, S2 and S3. Also, we detected five QTLs(qKL6, qKW3, qKW7, qKW6 and qRLW6) in S1, S2 and S3, which were not found in the Nipponbare/Z741 F2 population. However, qNPB3, qNPB7 and qPL3 QTLs were not validated by the three SSSLs in 2019, suggesting that minor QTLs are susceptible to environmental factors. These results lay the foundation for studying the biodiversity of kernal length and molecular breeding of different kernel types. | Wang Hui Zhang Jiayu Naz Farkhanda Li Juan Sun Shuangfei He Guanghua Zhang Ting Ling Yinghua Zhao Fangming | 2020 | Rice science2020，27，5： | 5 |
| 5 | Solubilities of 1-Methyl-3-(3-sulfopropyl)-imidazolium Hydrogen Sulfate in Selected Solvents显示文摘Ionic liquid 1-methyl-3-(3-sulfopropyl) -imidazolium hydrogen sulfate([C3SO3HMIM][HSO4]) was synthesized and characterized by infrared spectroscopy(IR) ,nuclear magnetic resonance(1H and 13C NMR) and ultraviolet-visible(UV-Vis) spectra. Its thermal stability was also examined by thermogravimetric analysis(TGA) and a differential scanning calorimeter(DSC) . The mole fraction solubilities of [C3SO3HMIM][HSO4]) in 12 selected solvents(n-pentane,n-hexane,n-heptane,benzene,toluene,ethylbenzene,acetone,2-butanone,3-methyl-2-butanone,tetrahydrofuran,ethyl acetate and dichloromethane) in the temperature range from 289.15 to 363.15 K were meas-ured using a static analytical method and correlated with an empirical equation. | CAI Shuangfei WANG Lisheng YAN Guoqing LI Yi | 2010 | Chinese Journal of Chemical Engineering2010，18，6： | 5 |
| 6 | Research on soil multi-media environmental pollution around a Pb-Zn mining and smelting plant in the karst area of Guangxi Zhuang Autonomous Region,Southwest China显示文摘The method of principal component analysis was applied to systematical research on the soil multi-media environment, including soil, surface water, ground water, waterbody sediment and agricultural crops, as well as pollution-inducing wastewater, mullock (or waste ore) and slag in the periphery of a large-sized Pb-Zn mining and smelting plant in a karst area of Guangxi Zhuang Autonomous Region. The results revealed that soils in the area studied have been heavily polluted by Cd, Zn, Pb and Hg, and the levels of these metals in the samples of agricultural crop greatly exceed the standards. The above-mentioned pollutants exist in all soil-multi-media environments. The mullock, slag, wastewater, surface water, ground water, soil, and agricultural crops constitute a composite ecological chain. Therefore, the improper disposal of mullock and slag, and the use of polluted wastewater for agricultural irrigation are the main causes of soil pollution. Heavy metals in the soil have three transition progresses: point (improved soil with slag, ground water inflow plot), linear (river transition) and non-point transition (regional pollution by slag) patterns, and the tailing yard is the most important locus for heavy metals to release into the environment. | DENG Chaobing WANG Shuangfei LI Fasheng | 2009 | Chinese Journal Of Geochemistry2009，28，2： | 4 |
| 7 | Single-layer Rh nanosheets with ultrahigh peroxidase-like activity for colorimetric biosensing显示文摘When the dimensionality of layered compounds decreases to the physical limit, ultimate two-dimensional (2D)anisotropy and/or quantum confinement effects may lead to extraordinary physicochemical attributes.Here,we report single-layer Rh nanosheets (NSs)exhibiting ultrahigh peroxidase-like activity,far exceeding that of horseradish peroxidase (HRP)and of most known layered nanomaterialbased peroxidase mimics.Considering per NS as an active subunit,the Rh NSs displayed a catalytic rate constant (Kcat)as high as 4.45×10^5 s^-1to H2O2,two orders of magnitude higher than those of HRP and Rh nanoparticles.The high atom efficiency of the Rh NSs can be attributed to the full exposure of surface-active Rh atoms,which greatly facilitates electron transfer and formation of superoxide anions,representing reactive oxygen species in the catalytic process.As a proof- of-concept application,the Rh NSs were successfully used as peroxidase mimics for the colorimetric detection of H2O2 and xanthine,with high sensitivity and selectivity.Moreover,a simple,rapid,and sensitive Rh-based paper sensor for ascorbic acid was also developed.In summar^this work provides a novel example of single-layer metallic NSs for biosensing. | Shuangfei Cai Wei Xiao Haohong Duan Xixi Liang Chen Wang Rong Yang Yadong Li | 2018 | Nano Research2018，11，12： | 3 |
| 8 | Biofilm response and removal via the coupling of visible-light-driven photocatalysis and biodegradation in an environment of sulfamethoxazole and Cr(Ⅵ)显示文摘The widespread contamination of water systems with antibiotics and heavy metals has gained much attention.Intimately coupled visible-light-responsive photocatalysis and biodegradation(ICPB)provides a novel approach for removing such mixed pollutants.In ICPB,the photocatalysis products are biodegraded by a protected biofilm,leading to the mineralization of refractory organics.In the present study,the ICPB approach exhibited excellent photocatalytic activity and biodegradation,providing up to~1.27 times the degradation rate of sulfamethoxazole(SMX)and 1.16 times the Cr(Ⅵ)reduction rate of visiblelight-induced photocatalysis.Three-dimensional fluorescence analysis demonstrated the synergistic ICPB effects of photocatalysis and biodegradation for removing SMX and reducing Cr(Ⅵ).In addition,the toxicity of the SMX intermediates and Cr(Ⅵ)in the ICPB process significantly decreased.The use of MoS_(2)/CoS_(2)photocatalyst accelerated the separation of electrons and holes,with·O_(2)^(–)and h+attacking SMX and ereducing Cr(Ⅵ),providing an effective means for enhancing the removal and mineralization of these mixed pollutants via the ICPB technique.The microbial community results demonstrate that bacteria that are conducive to pollutant removal are were enriched by the acclimation and ICPB operation processes,thus significantly improving the performance of the ICPB system. | Liushu Pan ZhouWan Qilin Feng Jue Wang Jianhua Xiong Shuangfei Wang Hongxiang Zhu Guoning Chen | 2022 | Journal of Environmental Sciences2022，34，12： | 2 |

| 10 | Fabrication of highly water-repelling paper by surface coating with stearic acid modified calcium carbonate particles and reactive biopolymers显示文摘Cellulose paper is the most attractive green packaging material due to its recyclability, renewability, sustainability and biodegradability. In some applications, paper with a high level of water resistance is desirable to meet specific requirements in modern packaging fields. This research aimed to develop a water-repelling paper with cost-effective and nontoxic materials. Commercial precipitated calcium carbonate (PCC) particles were modified by stearic acid (SA) and incorporated with soybean oil-based binder as a water repelling coating agent. The water-repelling efficiency of the coated paper was highly dependent on the ratio of SA / PCC as well as the binder content in the coating formula. PCC particles modified with 12wt% SA were efficient in increasing the water contact angle (WCA) of the coated paper to 146° at a coating weight of 5 g/m2. The binder for the coating was synthesized with acrylated epoxidized soybean oil (AESO) through Michael addition reaction. The triglyceride structure in the polymer chain imparted good bio-degradability to the binder polymer. It was found that surface modification of PCC with stearic acid played an important role in improving the WCA of paper. A super hydrophobic paper with a WCA of 162° was fabricated with a coating formula of 60% SA-modified PCC and 40 wt% AESO-binder. | Zhiwei Wang Min Yi Zheyun Zhang Mengya Guo Peng Lu Zheng Chen Shuangfei Wang | 2017 | Journal of Bioresources and Bioproducts2017，2，2： | 2 |

| 17 | Bio-modification of eucalyptus chemithermomechanical pulp显示文摘Eucalyptus chemithermomechanical pulp(CTMP)was modified with the white-rot fungus 19-6 in a stationary culture condition.Different factors that influence the effect of white-rot fungus treatment,including additional nutrition,pH value,temperature,treatment time and oxygen input were investigated.The results show that the energy consumption of post refining of CTMP treated by white-rot fungus 19-6 was lower than that of untreated pulp and the strength properties also obviously improved.At a freeness level of about 330 mL,compared to the untreated pulp,the tensile index,tear index and internal bonding strength increased by 21.3%,27.4% and 33.1%,respectively.Unfortunately,the treatment with white-rot fungus substantially decreased all optical properties except for opacity,which was essentially unchanged.Brightness and light scatter-ing coefficient were reduced to as much as 25%and 21%compared to the untreated pulps.However,after a tow-stage“Na_(2)S_(2)O_(4)-H_(2)O_(2)”bleaching,the final brightness can reach 70.3%ISO,which is similar to that of the untreated CTMP. | Qifeng YANG Huaiyu ZHAN Shuangfei WANG Kecheng LI Shiyu FU | 2008 | Frontiers of Chemical Science and Engineering2008，2，1： | 0 |
| 18 | Rational Design of Cellulosic Triboelectric Materials for Self‑Powered Wearable Electronics显示文摘With the rapid development of the Internet of Things and flexible electronic technologies,there is a growing demand for wireless,sustainable,multifunctional,and independently operating self-powered wearable devices.Nevertheless,structural flexibility,long operating time,and wearing comfort have become key requirements for the widespread adoption of wearable electronics.Triboelectric nanogenerators as a distributed energy harvesting technology have great potential for application development in wearable sensing.Compared with rigid electronics,cellulosic self-powered wearable electronics have significant advantages in terms of flexibility,breathability,and functionality.In this paper,the research progress of advanced cellulosic triboelectric materials for self-powered wearable electronics is reviewed.The interfacial characteristics of cellulose are introduced from the top-down,bottom-up,and interfacial characteristics of the composite material preparation process.Meanwhile,the modulation strategies of triboelectric properties of cellulosic triboelectric materials are presented.Furthermore,the design strategies of triboelectric materials such as surface functionalization,interfacial structure design,and vacuum-assisted self-assembly are systematically discussed.In particular,cellulosic self-powered wearable electronics in the fields of human energy harvesting,tactile sensing,health monitoring,human–machine interaction,and intelligent fire warning are outlined in detail.Finally,the current challenges and future development directions of cellulosic triboelectric materials for self-powered wearable electronics are discussed. | Xiangjiang Meng Chenchen Cai Bin Luo Tao Liu Yuzheng Shao Shuangfei Wang Shuangxi Nie | 2023 | Nano-Micro Letters2023，15，8： | 0 |
| 19 | Molecular Dynamics Simulation of Shock Response of CL-20 Co-crystals Containing Void Defects显示文摘To investigate the effect of void defects on the shock response of hexanitrohexaazaisowurtzitane(CL-20)co-crystals,shock responses of CL-20 co-crystals with energetic materials ligands trinitrotoluene(TNT),1,3-dinitrobenzene(DNB),solvents ligands dimethyl carbonate(DMC) and gamma-butyrolactone(GBL)with void were simulated,using molecular dynamics method and reactive force field.It is found that the CL-20 co-crystals with void defects will form hot spots when impacted,significantly affecting the decomposition of molecules around the void.The degree of molecular fragmentation is relatively low under the reflection velocity of 2 km/s,and the main reactions are the formation of dimer and the shedding of nitro groups.The existence of voids reduces the safety of CL-20 co-crystals,which induced the sensitivity of energetic co-crystals CL-20/TNT and CL-20/DNB to increase more significantly.Detonation has occurred under the reflection velocity of 4 km/s,energetic co-crystals are easier to polymerize than solvent co-crystals,and are not obviously affected by voids.The results show that the energy of the wave decreases after sweeping over the void,which reduces the chemical reaction frequency downstream of the void and affects the detonation performance,especially the solvent co-crystals. | Changlin Li Wei Yang Qiang Gan Yajun Wang Lin Liang Wenbo Zhang Shuangfei Zhu Changgen Feng | 2024 | Defence Technology(防务技术)2024，31，1： | 0 |
| 20 | Genomic characterization and molecular dating of the novel bacterium Permianibacter aggregans HW001T,which originated from Permian ground water显示文摘The Permian Basin is a unique ecosystem located in the southwest of the USA.An unanswered question is whether the bacteria in the Permian Basin adapted to the changing paleomarine environment and survived in the remnants of Permian groundwater.In our previous study,a novel bacterial strain,Permianibacter aggregans HW001T,was isolated from micro-algae cultures incubated with Permian Basin waters,and was shown to originate from the Permian Ocean.In this study,strain HW001T was shown to be the representative strain of a novel family,classified as‘Permianibacteraceae’.The results of molecular dating suggested that the strain HW001T diverged~447 million years ago(mya),which is the early Permian period(~250 mya).Genome analysis was used to access its potential energy utilization and biosynthesis capacity.A large number of transporters,carbohydrate-active enzymes and protein-degradation related genes have been annotated in the genome of strain HW001T.In addition,a series of important metabolic pathways,such as peptidoglycan biosynthesis,osmotic stress response system and multifunctional quorum sensing were annotated,which may confer the ability to adapt to vari-ous unfavorable environmental conditions.Finally,the evolutionary history of strain HW001T was reconstructed and the horizontal transfer of genes was predicted,indicating that the adaptation of P.aggregans to a changing marine environment depends on the evolution of their metabolic capabilities,especially in signal transmission.In conclusion,the results of this study provide genomic information for revealing the adaptive mechanism of strain HW001T to the changing ancient oceans. | Shuangfei Zhang Russell T.Hill Hui Wang | 2023 | Marine Life Science & Technology2023，5，1： | 0 |
