Abstract

• This research deals with the isolation and identification of soil fungi from Patheingyi Township in Mandalay Region during July to September, 2018. The soil samples collected from Yay Kyi and Shin Taw Gone Villages. And then, soil samples were undertaken by chemical treatment dilution method. Four fungi were isolated from Yay Kyi and six fungi were isolated from Shin Taw Gone Villages. The morphology of ten isolated fungi the surface view and reverse view are different color. Ten isolated strains were tested by five test organisms for preliminary study of antimicrobial activities. Among them, four fungi showed the antibacterial activity against on Bacillus subtilis and Xanthomonas oryzae, three fungi showed the antibacterial activity against on Escherichia coli and Pseudomonas fluorescens, six fungi showed antifungal activities against on Candida albicans. ZN-01, ZN-02, ZN-04, ZN-05, ZN-06, ZN-07 and ZN-10 showed the antimicrobial activity against on all test organisms. Moreover, ZN-03, ZN-08 and ZN-09 cannot show the antimicrobial activity against on all test organisms. Especially, ZN-10 showed highest antimicrobial activity of clear zone (28.12 mm) against on Pseudomonas fluorescens. Therefore, this strain ZN-10 was selected for further investigation. According to the morphological character, microscopical character and references keys, the fungus ZN-10 is preliminarily identified as Purpureocillium sp.
