A distinctive screening procedure resulted in the isolation and identification of antituberculotic actinobacteria. In this course, a total of 125 actinobacteria were isolated from various soil samples from untapped areas in Northwestern Himalayas, India. The antibacterial screening showed that 26 isolates inhibited the growth of at least one of the tested bacterial pathogens including Staphylococcus aureus (ATCC 25923), Staphylococcus epidermidis (ATCC 12228), Bacillus subtilis (ATCC 11774), Micrococcus luteus (ATCC 10240), Escherichia coli (10536), Pseudomonas aeruginosa (ATCC 10145) and Klebsiella pneumonia (ATCC BAA-2146). The production media was optimized for the active strains by estimation of their extract value by the quantification of the ethyl acetate extract. The screening of fermentation products from the selected 26 bioactive isolates revealed that 10 strains have metabolites antagonistic against the standard H37Rv strain of Mycobacterium tuberculosis. The characterization by 16S rRNA gene sequencing and phylogenetic analysis demonstrated the diverse nature of these antituberculosis strains. The secondary metabolites of potent, rare strain, Lentzea violacea AS08 exhibited promising antituberculosis activity with minimal inhibitory concentration (MIC) of 3·9 μg ml-1 . The metabolites identified by gas chromatography-mass spectrometry (GC-MS) included, Phenol, 2,5-bis (1, 1-dimethylethyl), n-Hexadecanoic acid, Hexadecanoic acid methyl-ester, Hexadecanoic acid ethyl-ester and, 9,12-Octadecadienoyl chloride(Z,Z) are biologically significant molecules.The study presents the isolation of rare actinobacteria from untapped sites in the Northwestern Himalayas and their in vitro potential against Mycobacterium tuberculosis for their metabolites. The study revealed that exploring the untapped natural sources as one of the resourceful approaches for the discovery of new natural products. This study also provided strong evidence for the ability of rare and potent actinobacterial strains to produce bioactive compounds with antagonistic activity and these metabolites can be studied for inhibitory potential.
