Abstract

The purpose of this study was to isolate Actinomycetes bacteria from mangrove soil and antimicrobial test against Escherichia coli and Staphylococcus aureus. Soil sampling was conducted using zigzag. Actinomycetes isolation was carried out with surface plate while the potency test isolates was done with diffusion method. A total of 2 isolates of Actinomycetes were isolated, namely Isolate RR-1 with the color of white colonies and Isolate RR-2 with colony color of gray. Two isolates of the RR-1 were able to inhibit the growth of bacteria E. coli and S. aureus, while the RR-2 was only able to inhibit the bacteria E. coli.
