Characterisation of Streptomycetes from Lignite Mines and their Antagonistic Activity Against Bacteria and Fungi

摘要

It has been well established that microorganisms are virtually an unlimited source of natural products, many of which have potential therapeutic applications. Among the various organisms the filamentous soil bacteria of the genus Streptomyces are remarkable and are considered as a potential source of important bioactive compounds. In the present study we have isolated actinomy-cetes from six locations in Neyveli lignite mine area, Tamilnadu, India and tested for their antagonistic activity. Seven isolates, which possess good antagonistic activity against bacterial and fungal pathogens, were selected and all the isolates represented the genus Streptomyces. The isolates have been identified up to the species level as per ISP procedures. The results of the study prove that the lignite mines are very promising zone for potential actinomycetes.
