heavy DNA metagenome from freshwater aquarium biofilters sample Raw sequence reads
Normal metagenome sequecing of Prokaryota in heavy DNA from recirculating aquaculture systems (RAS).As a newly discovered group of ammonia-oxidizing microorganisms, complete ammonia oxidizing (comammox) Nitrospira has been widely found in various oligotrophic ecosystems. However, their activity and ecological niche are still unclear in RAS. This study aimed to elucidate microbial community structure and metabolic versatility of active comammox Nitrospira, ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) in RAS.
