摘 要: 从云南洱源采集的土壤样品中分离到1株链霉菌YIM31249TT.该菌株具有很强的抗菌活性.通过对其进行的包括形态、生理生化特性、细胞壁化学组份以及16SrDNA序列等方面的研究,确定其为链霉菌属的一个亚种,我们将其命名为生黑孢链霉菌洱源亚种(Streptomycesmelanosporofacienssubsperyuanensis).菌株YIM31249T气生菌丝和基内菌丝均很丰富,孢子链较长且为螺旋状,部分孢子链螺旋成假孢囊,孢子表面粗糙不带刺,基丝不断裂. One actinomycete strain YIM31249T,which had strong antimicrobial activity,was isolated from a soil sample collected from eryuan,Yunnan Province.Based on its morphology,physiological and biochemical characteristics,chemotaxonomy and 16S rDNA sequence analysis,we proposed it as a new subspecies of genus Stretomyces and named it as Streptomyces melanosporofaciens subsp eryuanensis. Strain YIM31249T grew well on most test media.The aerial and substrate mycelium were abundant and the spore chains were long and...
