用综合纸层层析法分析了72株从神农架林区和自然保护区土壤分离出来的,并经过鉴定的链霉菌产生的抗生素类型,将其与已知抗生素的纸层层析图谱进行比较。结果表明,供试的链霉菌能产生出多种不同的抗生素,有的层析谱型易于归类;有的层析谱型则缺乏规律性,不能确定其所属类型。分析结果还表明抗生素的产生具有菌株特异性。
A total of 72 strains of Streptomyces isolated from the soil of Shennongjia forest and nature reserve were analyzed by comprehensive paper chromatography. The antibiotic types of Streptomyces were identified and compared with the paper layer chromatograms of known antibiotics. The results showed that Streptomyces can produce a variety of different antibiotics, and some chromatographic profiles easy to classify; some chromatographic profiles are lack of regularity, can not determine its type. The results of the analysis also indicate that the antibiotic production is strain-specific.
