Increasing the amount of feeding in shrimp culture feeding will trigger the accumulation of organic matter and toxic compounds in the form of waste in the pond. One of the effort that can be done is bioremediation or the return system of environmental conditions that are polluted through the addition of certain bacteria. This research aims to identify bioremediation degradation bacteria in shrimp pond waste. This study was held in November 2019 - March 2020. Twelve isolates of bacteria wich isolated from the shrimp pond sediment at Pasir Sakti, East Lampung and cultured on sewage media. Subsequent samples were screened to select total ammonia nitrogen (TAN) degradation bacteria candidates. Bacterial isolates with the best activity are subsequently identified morphologically including cell form, Gram test, motility, and molecular identification with 16S rRNA sequential analysis. The results showed that the best isolate were able to reducing TAN was T4.10 isolate with activity able to reduce TAN by 0,404 mg/L. Morphological, biochemical, and molecular identification confirm that the isolate was 100% Bacillus Megaterium bacteria. These bacteria can be used as bioremediation candidates. Shrimp pond waste will be degraded into compounds that can be reused for shrimp metabolic processes, so the sustainability aquaculture can happened.
