“…Candidatus Aquiluna, a photoheterotroph ( Kang et al, 2012 ), was reportedly positively correlated with the microbial metabolic activity of organic nitrogen ( Lukwambea et al, 2020 ). Pseudomonas furukawaii ZS1, Acidovorax facilis , Citrobacter diversus , and certain Thauera species also participate in nitrogen removal in aquaculture ponds ( Mai et al, 2021 ; Niu et al, 2022 ). Our results showed that Dechloromonas , Limnohabitans , Candidatus Aquiluna, and Pseudomonas were detected in the pond water and sediment microbiota.…”
