Desulfovibrio spp. is the main causes of hydrogen sulfide H2S gas and organic pollution in shrimp ponds. The amount
of food deposited at the pond bottom provides favorable conditions for the growth of H
2S gas-producing bacteria.
Many studies have shown that the use of antibiotics to treat bacteria led to the emergence of multidrug resistant
strains, which has raised awareness of the critical need for alternative antimicrobials. Bacteriophages – viruses that
infect and inhibit bacterial cells – are currently of great interest as highly viable alternative to antibiotics. The purpose
of this study is to evaluate the effectiveness of bacteriophage in controlling H
2S producing bacteria in shrimp ponds.
The bacterial strains were identified based on morphological, physiological, and biochemical criteria. The bacterial
species was molecularly identified using the 16S rRNA gene sequencing, and phage strains capable of inhibiting H
2S
gas-producing bacteria were investigated by agar spot test and plating method. The result investigated six strains of
bacteria,
Desulfovibrio spp., that were isolated from the shrimp pond. This study showed that phages L12 and T0
could infect bacteria
Desulfovibrio spp. and prevent the growth of the bacteria 11D as well as prevent the generation
of H
2S gas.
