The enrichment characterization of Nitrospira under high DO conditions. Nitrospira.sp

Nitrite-oxidizing bacteria are crucial to nitrification and nitrogen elimination in wastewater treatment. Mass reports exist on the links between NOB and other microorganisms, for instance, ammonia-oxidizing bacteria. However, a few studies exist on the enrichment characterization of NOB under high dissolved oxygen conditions. In this study, NOB was designed to be enriched individually under high DO conditions in a continuous aeration sequencing batch reactor, and the kinetic characterization of NOB was evaluated.
