Abstract

Ganoderma boninense was evaluated for their antimicrobial and antifungal activities against bacteria Staphylococcus aureus, Escherichia coli, Bacillus cereus and fungus Candida albicans. The fruiting bodies were extracted with 95% ethanol and the crude extract was used to test in paper disc diffusion method and Germ Tube test. In antimicrobial activities test, volumes, temperatures, concentrations and periods of storage crude extract were considered and those factors may affect the size of diameter inhibition zone. The results revealed that the ethanolic extracts of G boninense inhibited effectively against growth of S. aureus, following by B. cereus and E. coli. However, temperature gave no significant effect against studied bacteria. In antifungal activities, high concentration of G boninense crude extract was found to be capable of decrease the germination and germ-tube length of the C. albicans spores. Based on the current findings, it can be concluded that G boninense has antimicrobial and antifungal activities, which were potent as antimicrobial agents.
