The PCR-based Screening of the Cosmid Library from Streptomyces lavendulae var. hainanensis PCR方法筛选淡紫灰链霉菌海南变种基因组粘粒文库
Antibiotic I-4200, which was active against Pseudomonas aeruginosa, was isolated from the fermentation broth of a strain of Streptomyces lavendulae. Based on its physico-chemical properties and spectral evidences, I-4200 has been identified as trehalosamine ( Fig.9). 从链霉菌I-4200的发酵液中分离到具抗铜绿假单胞菌作用的物质I-4200,基于理化性质和光谱数据,I-4200已鉴别为海藻糖胺(trehalosamine)。
