| Abstract/Description: | The rapidly growing aquaculture industry is associated with numerous environmental problems, especially nitrogen pollution. The HNAD (heterotrophic nitrifying/aerobic denitrifying) bacteria emerging as efficient nitrogen removal life forms were characterized and compared in shrimp pond and effluent discharge channel from the aspects of composition and function. Eighty three HNAD bacterial strains belonging to the Proteobacteria, Firmicutes, Actinobacteria and Deinococcus-Thermus were found. Alpha diversity index by Shannon and Chao1 showed more diverse genera in effluent channel than shrimp pond water. The mean potential nitrate-N removal activity was significantly higher in effluent channel water (15.57 ± 3.39) as compared to shrimp pond (9.06 ± 5.76). Nitrate reduction, nitrate respiration and aerobic chemoheterotophy were significantly higher in effluent channel than shrimp pond. This study will help in understanding and developing culturable HNAD bacteria for successful transformation of nitrogenous waste in coastal aquaculture and wastewater treatment systems. |
