Description
Summary:Vibrio sp. are one of the primary disease-causing pathogenic agents in shellfish aquaculture, ubiquitous throughout the world. With the rise of the antibiotic resistance phenomena, and current antibiotics cannot assure efficient control of luminescent vibriosis, it is primordial to to look for novel sources of antimicrobials. Along with the extensive research on isolating bioactive compounds from plants, research on the biodiversity of fungal endophytes has also received much attention. This study aims to isolate endophytic fungi from stem-barks and leaves of mangrove plants as mangroves exist under stressful conditions which let them able to produce diverse group of metabolic substances with wide range of biological activities including antimicrobial agents. Mangrove samples were taken from Bengkalis district, Riau Province, and identified as Ceriops tagal (Perr.) C.B.Rob and Bruguiera sp. A total of 22 isolates of fungal endophytes have been isolated and screened for their ability to inhibit the growth of Vibrio alginolyticus and Vibrio parahaemolyticus. Antagonist test results showed that 4 isolates were able to inhibit the growth of Vibrio parahaemolyticus with 10.46 ± 0.33 to 14.29 ± 0.12 mm of inhibition zone, while the growth of Vibrio alginolyticus was inhibited by 11 isolates with inhibition diameter of 9.72 ± 0.7 to 15.45 ± 1.3 mm. One isolate is able to inhibit the growth of these two pathogenic bacteria and has been identified as Aspergillus sp. These findings indicate the potential of endophytes in producing secondary metabolites with anti-vibriosis activity.
