摘要: 从红沙公园的红树林泥土中分离得到一株生产较强抑菌活性次级代谢产物的放线菌Strepomyces costaricanus SCSIO ZS0073,采用滤纸片法进行抑菌活性追踪,并利用硅胶、凝胶柱层析和HPLC等分离手段对其发酵产物进行分离纯化,得到3个化合物,通过NMR、MS等波谱数据分析并参阅文献将3个化合物分别鉴定为放线菌素D、放线菌素X-O β和制霉色基素(fungichromin)。其中放线菌素D在发酵条件未优化的情况下产量就达到300 mg/L以上。

Abstract: An actinomycete strain Stremptmeces costaricanus SCSIO ZS0073 producing strongly antibacterial metabolites was isolated from the soil collected in Hongsha park.Guided by antibacterial assay,its fermentation was isolated and purified by Silica gel column,Sephadex LH-20 and HPLC.Three compounds were obtained,which were identified as actinomycin D(1),actinomycin XO-β(2) and fungichromin(3) by MS and NMR spectroscopic analysis.The output of actinomycin D was more than 300 mg/L,even under nonoptimized growth conditions.

Key words: mangorove-derived actinomycetes, antibacterial activity, secondary metabolites, actinomycins, fungichromin
