Isolation and Identification of a Heterotrophic Nitrifying Bacteria and Study on Removal of Nitrite Nitrogen

Abstract:

A bacteria strain for efficiently removing nitrite nitrogen was isolated and purified from sediment in shrimp pond, and the morphology of bacteria was observed using scanning electron microscopy, and the homology analysisof 16SrDNA sequence of the strain was conducted. The results showed that the strain was identified as Acinetobacter baumanii according to the morphological characteristics, physiological and biochemical characteristics and 16SrDNA sequence analysis. The isolated strain had a high heterotrophic nitrification function, the removal rate of nitrite nitrogen reached 97.17% after 12 h.
