Abstract

Marchantia polymorpha is a type of liverwort that is often used by the Indonesian people, especially the Maninjau West Sumatra community as a source of traditional medicine in dealing with infections of the skin. This moss is known to have simple terpenoids and phenolics (flavones and flavones glycosides) which are antimicrobial compounds. To obtain these compounds, of course requires large amounts of moss, this has the potential to disrupt ecological stability. To avoid this problem, endophytic bacteria that have the potential to produce antibiotics are used. The stage of this study starts from sampling, isolation and screening of antibiotic-producing endophytic bacteria and macroscopic, microscopic and biochemical tests. The purpose of this study was to obtain endophytic bacterial isolates that could potentially produce antibiotics in S. aureus test bacteria. Six isolates of endophytic bacteria that have the potential to produce antibiotics were successfully isolated. Isolates with code BEMP-09 were the best isolates in inhibiting the growth of S. aureus pathogenic bacteria in the medium category.
