Abstract
Botryosphaeria rhodina is an endophytic fungus that most found in tropical fruit plants
such as mangroves. Previous studies reported that B. rhodina derived from the mangrove
plant Xylocarpus granatum has the potential to produce good antibacterial activity.
However, the Gram-negative antibacterial activity of this endophytic fungal extract is still
rarely studied. This study aimed to test the antibacterial activity of Gram-negative
endophytic fungi extract B. rhodina against Salmonella typhimurium ATCC 14028,
Vibrio Algynolyticus ATCC 17749, and Vibrio parahaemolyticus ATCC 17802. The
results of the Gram-negative antibacterial assay carried out by the agar diffusion method
showed that the n-hexane extracts of the endophytic fungus B. rhodina at a concentration
of 500 g/mL had weak activity with an inhibition zone diameter of 13-19 mm against
Gram-negative bacteria.
