摘要: 放线菌FIM 95-F1的形态特征、培养特性及生理生化特征和16S rDNA 序列分析表明该菌属于Streptomyces castelarensis的一个变种,暂定名为S. castelarensis FIM 95-F1。本研究利用高速逆流色谱分离和结晶法相结合的方法从放线菌FIM 95-F1胞内分离纯化抗真菌抗生素S1。化合物理化性质和UV、IR、MS以及NMR等波谱分析结果表明化合物S1与抗真菌抗生素Scopafungin同质,为36元环大环内酯类抗生素。S1对白色念珠菌(Candida albicans)、黑曲霉(Aspergillus niger)及红酵母(Rhodotorula sp.)均有抗菌活性,其MIC分别为0.234 µg/mL、0.469 µg/mL和0.234 µg/mL。

Abstract: Based on the taxonomic study, the antifungal antibiotic S1 producer FIM95-F1 was named as Streptomyces castelarensis FIM 95-F1 tentatively. The bioactive metabolite S1 was isolated and purified from the mycelia of strain FIM 95-F1 using high speed countercurrent chromatography (HSCCC) and crystallization methods. Basic physico-chemical properties and UV, IR, MS, and NMR spectra data suggested that antibiotic S1 was identical with Scopafungin, a 36-membered ring macrolide antibiotic. Antibiotic S1 showed potent antifungal activity against Candida albicans, Rhodotorula sp., and Aspergillus niger with MIC value of 0.234 µg/mL, 0.234 µg/mL, and 0.469 µg/mL, respectively.

Key words: Streptomyces castelarensis, isolation and purification, structure, scopafungin
