Abstract

Marine anammox bacteria (MAB) have been regarded as playing a crucial role in regulating the global nitrogen flux. MAB maintains biological activity and stable nitrogen removal in the range of 0-50 g/L NaCl. This characteristic shows its promising application in nitrogen removal from saline or hypersaline wastewater. However, currently the enrichment, application and genomic studies on anammox bacteria focus more on the freshwater anammox bacteria. Limited work has been carried out on marine anammox bacteria. In this work, the enrichment of MAB was conducted with a non-woven fabric reactor and a membrane bioreactor (MBR). The enriched MAB will be further used for meta-omics sequencing analysis to decode its metabolic versatility. This study aims to unveil the evolution of microbial community dynamics and metabolic functions of enriched MAB, bridge the knowledge gaps in the MAB genome database, and enhance our comprehension of its pivotal role in the marine ecosystem’s global nitrogen cycle.
