The Potential Use Of Mangrove-Derived Streptomyces sp. As Probiotics Against Vibrio Parahaemolyticus Infection In Aquaculture Farming

This thesis aims to explore a sustainable alternative to antibiotics in controlling bacterial infections in aquaculture. In particular, it investigates the potential of introducing mangrove-derived Streptomyces sp. as probiotics to control Vibrio sp. infections. It characterizes five Streptomyces isolates and identifies Streptomyces sp. MUM 195J as a promising probiotic strain that demonstrates a strong inhibitory effect against Vibrio parahaemolyticus. In-vitro tests show that supplementation with Streptomyces sp. MUM 195J significantly increases the survival rate of Macrobrachium rosenbergii, enhances their growth, elevates their immune function, and improves the water quality. This finding contributes to the mitigation of antimicrobial resistance and the promotion of global food security.
