Study on Antimicrobial activities of soil microorganisms from Pathein Area Aye Khaing Mon In the study of isolation of soil microorganisms, 20 different fungi, 20 different bacteria and 4 actinobacteria were isolated from ten different soil samples in Pathein Area. In the study of antimicrobial activities of forty four isolated soil microorganisms, four fungi (AA-04, AA-08, AA-13 and AA-15) showed the antibacterial activity against Agrobacterium tumefaciens and three bacteria (KK- 02, KK-10 and KK-17) against Staphylococcus aureus. Among them, only bacteria KK-10 showed the highest antibacterial activity against S. aureus. In the studies of time course of fermentation, it was observed that 100 ml volume of bacterium KK-10 started at 24 hrs and ended at 60 hrs. Based on the growth kinetics of bacteria KK-10, 60 hrs age and 2.5 % sizes of inoculum were optimized by using medium FM-1 for the production of metabolite against S. aureus. The maximum activity reached at 3 days fermentation (25.91 mm) on S. aureus. 2020-12-01 http://hdl.handle.net/20.500.12678/0000007108 https://meral.edu.mm/records/7108
