Endophytic Fungi Isolated from Rhizophora mucronata and Their Antibacterial Activity
Abstract: Mangrove plants are
known as source of traditional medicines. Endophytic fungi have an important
economic potential for antibacterial, enzyme and secondary metabolites that are
useful especially in pharmaceutical industry. The purpose of this research was
to determine the antibacterial activity of the endophytic fungal extracts from
mangrove plant Rhizophora mucronata against diarrhea causing bacteria. This
research included isolation, characterization, cultivation, extraction, and
antibacterial activity test. The study yielded 5 types of endophytic fungi with
different morphology. Endophytic fungus DS1 was the selected isolate based on
antagonism test. The growth pattern showed the stationary phase of isolate DS1
was on the 15th day. Culture broth extract showed considerable inhibition on
Pseudomonas aeruginosa with diameter of inhibition zone was 18.5 mm ± 3.32.
Extract of mycelium inhibited the growth of Staphylococcus aureus (2 mm). The
culture broth extract showed more potent antibacterial activity in comparison
with the mycelium extract.
