Abstract
HIGHLIGHTS Streptomyces sp. nkm1 was isolated from a marine soil sample and identified using morphological and molecular techniques. Streptomyces sp. nkm1 had the highest antifungal activity against some plant pathogenic fungi on M6 medium. On Aspergillus flavus, the minimum inhibitor concentration of ethyl acetate Crude extract of Streptomyces sp. nkm1 was more effective. The GC-MS analysis of the ethyl acetate extract revealed 26 components, with nonadecane being the most important bioactive compound.
