Isolation and characterization of a heterotrophic nitrifier Proteus mirabilis strain V7 and its potential application in NH4 +-N removal

Abstract: Ammonia (referring to both NH 3 and NH 4 + ), is one of the most toxic nitrogen forms, and is toxic to many aquatic organisms. The present study identified a heterotrophic nitrifier Proteus mirabilis strain V7, isolated from the coastal seawater. Almost 100 % of 82 mg L

“…The AMO enzyme has three subunits (AmoA, AmoB, and AmoC) and was the key enzyme involved in ammonia oxidation with an active site in AmoA. 23 The amoA gene, encoding putative AmoA, was amplified from the strain JQ1004 in this study. The PCR product size of amoA (606 bp) and 16S rDNA (1450 bp) genes was detected by 1.8% agarose gel electrophoresis.…”
