Antimicrobial and antifungal activity of soil actinomycetes isolated from coal mine sites

الملخص EN

In the current study, twenty-eight soil samples were collected from coalmine sites of Telangana, India.

the isolates were purified and identified based on their culture characterization on oatmeal agar, glycerol asparagine agar, yeast extract-malt extract agar, inorganic salt starch agar, and starch casein agar medium.

further, the supernatant of all the isolates were tested for antimicrobial and antifungal activities.

the biochemical and microscopic studies of isolated strains results indicates the potential isolate strains belongs to streptomyces genus.

among all the strains the biological activity of BHPL-KSKU5 showed higher anti-bacterial and anti-funagal activity.

the molecular characterization of BHPL-KSKU5 16s rDNA gene sequence and phylogenetic tree showed that is mostly related to the Streptomysis felleus (S.

felleus) strain.

this isolate was submitted to gene bank NCBI with accession number MH553077.

In addition, physiological studies such as utilization of carbon, nitrogen, amino acid sources of potential isolated were studied.

Further, optimization, purification and characterization of the novel compound producing strain may be helpful for discovering the new therapeutic microbial agent.
