Abstract

Isolation of different bacterial colonies from soil sample was carried out. All the isolated bacterial colonies were screened for their antagonistic activity against the pathogenic fungi. Antagonistic activity test was performed against pathogenic fungi (Aspergillus niger, A. flavus, Penicillium notatum and P. chrysogenum) and the best Zone of inhibition were occurs in Aspergillus flavus and Penicillium chrysogenum both (11 mm). Different test were performed to characterize the microbes. Microbes have anti-microbial properties that characterization of various antimicrobial substances as organics acids (lactic acid and formic acids), diacetyl, and hydrogen peroxide alone or in combination. Strain 1 (Escherichia coli) was more effective to inhibit the growth of Aspergillus niger, A. flavus, Penicillium notatum and P. chrysogenum.
