| Abstract | This research investigates the potential of Bacillus cereus ASAT-8, isolated from local Thai aquaponic systems, for enhanced organic matter decomposition. Aquaponics integrates hydroponics with aquaculture, necessitating the practical cycling of nutrients via microbial decomposition. This study isolated and characterized bacterial strains with high decomposition and nitrification capabilities. Water samples were collected, and twenty-one bacterial isolates were obtained using a modified Pep-Beef-AOB medium. Isolate ASAT-8, demonstrating high ammonia-oxidizing activity, was identified as Bacillus cereus (99% similarity) through partial 16S rRNA gene sequencing. Bacillus cereus ASAT-8 effectively reduced ammonia levels in organic waste, suggesting its potential to improve water quality. The widespread presence of Bacillus spp. Indicates a reliance on natural microbial resources in aquaponics. Incorporating Bacillus spp. can reduce water changes, minimize fish waste, and enhance food production. This study highlights the importance of Bacillus cereus for sustainable aquaponic practices, contributing to zero-waste food production. |
