Isolation and Identification of Antibacterial compound from Actinomycetes isolated from Mangrove soil

Abstract

Nine actinobacteria were isolated from the mangrove soil of Bhitarkanika and screened for their bioactive metabolites and antimicrobial property. Out of the nine actinobacterial isolates, the bacterial isolateBAB-7 showed positive activity towards most of the enzymesscreened,i.e., Cellulase, phosphate solubilization, L-asparaginase, protease, and amylase. The actinobacterial isolate BAB-7 also exhibited antimicrobial activity against K. pneumoniae, V. alginolyticus, V. parahaemolyticus, P. aeruginosa,E. coli, S. typhimurium, and S. salivarius. Based on biochemical characterization, the actinobacterial isolate BAB-7 was identified asSteptomcessp.The secondary metabolites produced by the bacterial strain were analyzed through GC-mass spectroscopy and found to besimilar to the peaks of2-cyclohex-3-en-1-yl-2-oxoacetic acid derivative (ketomycin).
