Exploration of Antibiotic Producing Bacteria from the Human Beard

This study aims to explore antibiotic producing bacteria from beards, test antibacterial activity on Escherichia coli and Staphylococcus aureus and characterize antibiotic producing bacteria from beards. Bacteria were isolated using the pour plate method, and then tested for antibacterial activity on E. coli and S. aureus using the disk method. After that, the morphology of each bacterial colony was observed macroscopically as well as microscopically, and biochemical tests were performed. A total of 9 bacterial isolates were successfully isolated from beards. Antibacterial activity test results from 9 isolates reveal that 6 isolates were obtained to be able to inhibit S. aureus, namely isolates Jg 1, Jg 2, Jg 3, Jg 4, Jg 5 and Jg 8. One isolate was able to inhibit the growth of E. coli, namely Jg 5 isolate. Bacterial isolates from beards which have antibacterial activity were identified using the Bergey's Manual of Determinative Bacteriology identification book and 3 genera of bacteria were obtained, namely Micrococcus, Planococcus and
