Isolation, identification and phylogenetic analysis of a nitrite degrading bacterium
A potential nitrite degrading bacterium AQ-3 was isolated and screened from the aquaculture sediment. The nitrite removal rate of AQ-3 was detected as 99. 47%. Strain AQ-3 was identified as Acinetobacter baumannii (JF751054) through API ID32GN bacterial identification system and 16S rDNA sequence analysis. Its 16S rDNA sequence had homology of 99% with those of Acinetobacter sp. submitted to GenBank.and showed the closest relative to Acinetobacter baumannii strain 14 (FJ907197). In addition,nirS gene、nirK gene and norB gene all existed in strain AQ-3. This study proved strain AQ-3 was a potential nitrite degrading bacterium,and enriched the microbial resources of nitrite degrading bacterium.
