BIOACTIVE METABOLITE PRODUCTION BY TRITIRACHIUM EGENUM ISOLATED FROM SOUTHEAST COAST OF ANDHRA PRADESH, INDIA
AbstractA study has been undertaken to isolate potent fungi from the South-east coastal zone of Andhra Pradesh. Among the 11 fungal strains isolated and screened, one potent strain with broad-spectrum antagonistic activity was found. Based on the morphological, cultural, and molecular characteristics, the potent strain was identified as Tritirachium egenum. Production of bioactive metabolites by the strain was high in malt extract broth compared to other media tested. The strain utilized mannitol and ammonium sulphate as good carbon and nitrogen sources for the elaboration of antimicrobial metabolites. The optimum pH and temperature for bioactive metabolite production by strain were recorded at 4.0 and 30°C, respectively. The secondary metabolites produced by the strain grown under optimal conditions exhibited high antagonistic activity against Gram-positive and Gram-negative bacteria and fungi. This is the first report of antimicrobial metabolites produced by Tritirachium egenum isolated from the south-east coast of Andhra Pradesh.
