Twenty-six morphotypes of actinomycetes bacteria were isolated from the soils of arid zone of Indian Thar desert, Rajasthan. A significant and positive correlation was found between density of actinomycetes isolates and availability of nitrogen in sandy soil of arid zone suggesting the influence of soil nitrogen on occurrence and propagation of actinomycetes in this region. Molecular identification based on 16S rRNA gene sequencing revealed that the bacterial isolates belong to four actinomycetes genera, viz. Streptomyces (22 species), Nocardiopsis (two species), Saccharomonospora (one species) and Actinoalloteichus (one species). The preliminary screening of 26 isolates against five human pathogenic bacteria, viz. Escherichia coli, Vibrio cholera, Salmonella enterica typhimurium, Staphylococcus aureus and Enterococcus faecalis, showed that only four isolates, viz. Streptomyces sp. (ITD-27), S. enissocaesilis (ITD-29), S. Malachitospinus (ITD-35) and Streptomyces sp. (ITD-47), had antibacterial activity. The secondary screening of these four isolates revealed that the isolate S. malachitospinus (ITD-35) showed the maximum growth inhibition zone and inhibited the growth of all tested gram-positive and gram-negative pathogenic bacteria. Gas chromatography-mass spectrometry analysis of S. malachitospinus (ITD-35) cultural filtrate in n-butanol solvent identified three antibacterial compounds of medicinal significance, viz. 3-octanone, neopentyl isothiocyanate and 2-methyl butyl isothiocyanate.
