放线菌是形形色色的细菌广泛分布在各种自然和人为环境。此本研究试图从地龙分离放线菌的演员和吲哚乙酸(IAA)的生产从选定的隔离。完全10 actinobacterial殖民地独立使用淀粉酪蛋白琼脂,琼脂提取fromearthwormcastmaterial fromAgricultural收集区域,Kanchipuram。所有的隔离都确认为放线菌基于他们的殖民和显微镜图像。所有的分离筛选用于生产氨、乙偶姻、磷酸盐溶液化和吲哚乙酸生产。10隔离,5显示乙偶姻生产9显示磷酸溶液化和六个隔离了吲哚乙酸的生产。进一步的研究是集中在IAA生产fromtwo actinobacterial隔离namelyCA4 CA6。生产、提取、分离和测定IAA的采用标准程序执行。IAA的数量产生的应变CA4 CA6被估计为15.4µg /毫升和19.8µg / ml,分别。微观、文化和actinobacterial隔离的生理特征进行了研究,采用标准程序。 Based on the phenotypic characteristics both the actinobacterial isolates (CA4 and CA6) are suspected as Streptomyces species. Finding of the present work concludes that cast soil is a potential source for plant growth promoting actinobacteria (PGPA). Optimization studies are needed to prove the potential of cast soil actinobacteria such as CA4 and CA6 as producer of Indole Acetic Acid (IAA).
