| 1 | Isolation and Preliminary Identification of Broad-spectrum Bacteriocin-producing Lactobacillus Strain CW3显示文摘[Objective]This study aimed to screen and preliminarily identify Lactobacillus strain CW3. [Method]Oxford cup double-plate method was used for preliminary screening of broad-spectrum bacteriocin-producing Lactobacillus strain; after eliminating the interference of organic acid and hydrogen peroxide,antibacterial substances containing protein properties produced by the screened strain were detected; finally,the obtained strain was identified. [Result]After elimination of interference factors such as organic acid and hydrogen peroxide,the fermentation supernatant of strain CW3 could still inhibit the growth of indicator strains; the antibacterial activity of fermentation broth was significantly reduced after treatment with trypsase and pepsase,which indicated that the produced antibacterial substances were bacteriocins. Results of physiological and biochemical identification showed that strain CW3 belonged to Lactobacillus plantarum. [Conclusion]CW3is a broad-spectrum bacteriocin-producing Lactobacillus plantarum strain. | Haoxin LV Weidong WANG Zhongfang TAN Feifei YANG Yingchun JIAO Yanping WANG Zongwei LI | 2014 | Agricultural Biotechnology2014，3，1： | 2 |
| 2 | Two-dimensional alloyed transition metal dichalcogenide nanosheets:Synthesis and applications显示文摘Two-dimensional(2D)transition metal dichalcogenide(TMD)nanosheets have attracted considerable attention owing to their diverse properties and great potential in a wide range of applications.In order to further tune their properties and then broaden their application domain,large efforts have been devoted into engineering the structures of 2D TMD nanosheets at atomic scale,especially the alloying technology.Alloying different 2D TMD nanosheets into 2D alloys not only offers the opportunities to fine-tune their physical/chemical properties,but also opens up some unique properties,which are highly desirable for wide applications including electronics,optoelectronics and catalysis.This review summarizes the recent progress in the preparation,characterization and applications of 2D alloyed TMD nanosheets. | Haoxin Huang Jiajia Zha Shisheng Li Chaoliang Tan | 2022 | Chinese Chemical Letters2022，33，1： | 1 |

| 4 | Mutualistic fungus Piriformospora indica modulates cadmium phytoremediation properties of host plant via concerted action of enzymatic and non-enzymatic biochemicals显示文摘Soils and ecosystems contaminated with cadmium (Cd) threaten human health and adversely affect morphological,physiological,and biochemical parameters of plants.The symbiotic association of endophytic fungi with their host plants is the best strategy to improve various plant characteristics and remediate soils polluted with heavy metal(loid)s (HMs).Being a well-known plant growth-promoting fungus,Piriformospora indica confers resistance against a number of abiotic stresses,including HM stress.This pot experiment explored the potential and ameliorative effects of P.indica on Artemisia annua L.plants treated with different concentrations (0,40,80,and 120 mg kg-1) of Cd.Inoculation with P.indica significantly increased plant performance,especially by enhancing chlorophyll concentration and water potential and by decreasing electrolytic leakage,when compared with un-inoculated plants,despite the high Cd levels.Similarly,P.indica enhanced antioxidant enzyme activities,thereby reducing the drastic effects of Cd in inoculated plants.In addition,P.indica accumulated Cd in the roots of colonized plants,as revealed by atomic absorption spectroscopy,and restricted Cd translocation to aerial parts.Furthermore,P.indica showed in vitro resistance (up to a certain level) to Cd stress;however,fungus growth was inhibited at very high Cd concentrations,proving it an excellent candidate for use as a potential phytoremediator in fields affected by Cd contamination.The transcriptional analysis showed that the signaling genes and artemisinin and flavonoid biosynthetic pathway genes were significantly upregulated in P.indica-co-cultivated plants when compared with un-inoculated plants,suggesting a fine collaboration between primary and secondary metabolisms to modulate resistance capacity and to enhance the phytoremediation capability of A.annua against Cd toxicity. | Muhammad KHALID Saeed UR-RAHMAN Haoxin TAN Lantian SU Pei ZHOU Nan HUI | 2022 | Pedosphere2022，32，2： | 0 |
| 5 | Growth of Tellurium Nanobelts on h-BN for p-type Transistors with Ultrahigh Hole Mobility显示文摘The lack of stable p-type van der Waals(vdW)semiconductors with high hole mobility severely impedes the step of low-dimensional materials entering the industrial circle.Although p-type black phosphorus(bP)and tellurium(Te)have shown promising hole mobilities,the instability under ambient conditions of bP and relatively low hole mobility of Te remain as daunting issues.Here we report the growth of high-quality Te nanobelts on atomically flat hexagonal boron nitride(h-BN)for high-performance p-type field-effect transistors(FETs).Importantly,the Te-based FET exhibits an ultrahigh hole mobility up to 1370 cm^(2) V^(−1) s^(−1) at room temperature,that may lay the foundation for the future high-performance p-type 2D FET and metal-oxide-semiconductor(p-MOS)inverter.The vdW h-BN dielectric substrate not only provides an ultra-flat surface without dangling bonds for growth of high-quality Te nanobelts,but also reduces the scattering centers at the interface between the channel material and the dielectric layer,thus resulting in the ultrahigh hole mobility. | Peng Yang Jiajia Zha Guoyun Gao Long Zheng Haoxin Huang Yunpeng Xia Songcen Xu Tengfei Xiong Zhuomin Zhang Zhengbao Yang Ye Chen Dong-Keun Ki Juin J.Liou Wugang Liao Chaoliang Tan | 2022 | Nano-Micro Letters2022，14，7： | 0 |
