An important step in the nitrogen cycle is the process called nitrification, which is performed by ammonia-oxidizing microorganisms (AOM): ammonia-oxidizing bacteria (AOB), ammonia-oxidizing archaea (AOA), and complete ammonia oxidizers (comammox). The question being researched was “when AOA and comammox are placed in direct competition for ammonium, who outcompetes who?” Comammox were only discovered in 2015, […]
A33-P: MBI 475/575: High Salinity Condition (U6)
Antarctic ecosystems are one of the few places where mankind has yet to significantly disturb the biogeochemical cycling of microorganisms. The goal of this study was to subject samples from Lake Fryxell, an Antractic freshwater lake, to high salinity conditions in order to observe compositional changes in the microbial communities and detect resilience. We conducted […]
