The genus Streptomyces is represented in nature by the largest number of species and varieties among the family Actinomycetaceae. They differ greatly in their morphology, physiology, and biochemical activities, producing the majority of known antibiotics. The morphological and biochemical characteristics of 71 Streptomyces spp. isolated from soil samples collected at different places of Venezuela, are presented. A comparative analysis using the statistical software Minitab shows that 67 of these isolates are presumably new strains, since they possess a very low percentage of similarity with other reported species. Only four isolates shared 100% identity with one, two or three reported Streptomyces spp.
链霉菌属在放线菌科中是自然界中物种和变种数量最多的属。它们在形态、生理和生化活性方面差异很大，能产生大多数已知的抗生素。本文介绍了从委内瑞拉不同地点采集的土壤样本中分离出的71种链霉菌的形态和生化特征。使用统计软件Minitab进行的比较分析表明，这些分离株中有67株可能是新菌株，因为它们与其他已报道物种的相似性百分比非常低。只有四株分离株与一、二或三种已报道的链霉菌物种具有100%的同一性。
