摘要
目的:从湖边树木下的土壤中筛选分离链霉菌并研究其抑菌活性。方法:通过对菌的形态学和生理生化特征分析确定其种属。通过滤纸片法研究其次级代谢物的抑菌谱。结果:分离得到的一株链霉菌Streptomyces.sp NJ0510,次级代谢产物能抑制G+细菌,抑菌圈可达10mm以上,而对大肠杆菌等没有抑制活性。结论:该菌代谢产物能够抗耐药的金色葡萄球菌,具有潜在的应用前景。
Objective： Isolation a new actinomyce strain from lake soft and study its activity.Methods： The morphological and biochemical charactern of Streptomyces .sp NJ0510 were investigated. The antibacterium activity of the metabolite was assayed by filter paper method. Result： The extracted metabolite can inhibit G^＋ bacteria,the diameter of inhibition zone was over 10 mm, but it made no function on E. coli. Conclusion： The metabolite has bright future in therapy for its inhibition of drug- resistant Stphylococcus.
