Screening and characteristics of ammonia nitrogen removal bacteria under alkaline environments.

ABSTRACT: The toxicity of ammonia nitrogen (AN) has always caused severe harm to aquatic animals in intensive aquaculture conditions, especially in saline-alkali aquaculture waters. The application of AN removal bacteria is a safe and effective method for controlling the AN concentration in aquaculture water through direct conversion to bacterial protein. However, there is still a lack of AN removal bacteria that are appropriate for saline-alkali aquaculture conditions. In this study, three AN removal strains, namely, Bacillus idriensis CT-WN-B3, Bacillus australimaris CT-WL5-10, and Pseudomonas oleovorans CT-WL5-6, were screened out under alkaline conditions from the alkali-tolerant strains distributed in carbonate saline-alkali soil and water environments in Northeast China.
