Actinomycetes Diversity in the Rhizosphere Soils of Different Medicinal Plants in Kolly Hills-Tamilnadu, India, for Secondary Metabolite Production

摘要

A study was undertaken to isolate actinomycetes from the soils which collected from Kolli Hills located at Salem District, Tamilnadu, India. The isolated actinomycetes were subjected to identify at the genus level and induce to produce bioactive secondary metabolites under in vitro condition. There were eight isolates obtained from different region of Kolli hills and studied for the detection of antimicrobial substances contained for it. These antimicrobial compounds were extracted and tested against some microorganisms like Streptococcus faecalis , Pseudomonas aeruginosa , Escherichia coli , Bacillus amyloliquefaciens , Staphylococcus aureus , C andida albicans and Cryptococcus neoformans . The results showed that out of eight, five isolates were found to be of potential antagonists against pathogens and thus proving the production of secondary metabolites, which has the potential to control a variety of pathogenic organisms.
