Screening and Identification of XJEG-GF-82 ,An Antagonistic Endofungi from Ephedra.glauca and Its Antagonistic Activity Study
摘要
Abstract
XJEG-GF-82,an endophytic fungus,with broad antifungal and antibacterial activity to common crop and animal pathogens,was isolated from the endophytes of E. glauca using agar diffusion method in this study. The diameters of its inhibition zone against Bipolaris maydis, Fusarium oxysporumf. sp. niveum, Escherichia coli, Bacillus subtilis and Staphyloccocus aureus were determined to be 18 mm,16 mm,19 mm,25 mm and 27 mm respectively. XJEG-GF-82 was finally identified as Aspergillus ochraceus according to the morphological properties and D1 D2 regional sequence. The metabolites of XJEG-GF-82 were detected to contain polysaccharides and alkaloids, and the total concentration of poly-saccharides reached 160. 233 μg/mL after medium optimization. XJEG-GF-82 has provided a potential microbial resource for developing new chemical and natural anti-pathogen agents.关键词
