Seaweeds were collected from Mandapam coastal area at Rameshwaram District. The genus of Gelidiella acerosa seaweeds was used in this study. 9 Streptomyces species were isolated by serial dilution method of 10? dilution. Various biochemical tests were carried out to characterize the species. SEM imaging proved that the morphological characteristics were well in the range of Actinomycetes. The spore morphology was found to be smooth Streptomyces species grown on yeast malt extract medium supplemented with 2mg/ml. L-tryptophan. Optical density was recorded. Tryptophan is a precursor for the production of IAA .Compounds from Streptomyces spp., were extracted with ethyl acetate. They were purified and identified by thin layer chromatography and the Rf value was recorded.
