Abstract
Botryosphaeria rhodina is an endophytic fungus that colonizes various species of woody
plants, one of which is mangrove plants. B. rhodina has attracted attention in research
because of its ability to produce secondary metabolites. Several studies have reported
these endophytic fungi to test their antibacterial activity, especially Gram-positive
bacteria against bioactive compounds from different hosts. However, in this study,
Gram-positive antibacterial activity tests (Staphylococcus aureus ATCC 6538, Bacillus
subtillis ATCC 19659 and Bacillus cereus ATCC 10876) were carried out from extracts
of B. rhodina from mangrove plants. The results showed the value of the clear zone of
the methanol extract and n-hexane extract on Gram-positive bacteria. Based on the
antibacterial test using the agar diffusion method, it showed moderate antibacterial
activity with the largest clear zone in the methanol extract, which was 20.11±2.1 mm in
B. subtilis bacteria.
