Abstract Details

2014, Master of Science, Miami University, Microbiology.
Ammonia oxidation within nitrification is performed by ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA). AOB and AOA have been detected in the same freshwater environments, and lake characteristics associated with specific trophic states have been suggested as mechanisms for niche differentiation. To investigate the influence of lake trophic state on niche differentiation between AOB and AOA, culture-dependent methods and culture-independent methods were utilized. Regardless of lake trophic state, the AOB grew faster than the AOA when grown in lake water and were also more abundant than the AOA. The AOA growth rates and abundances suggest that they may be more successful in mesotrophic/meso-oligotrophic lakes. It is possible that lake parameters characteristic of certain trophic states contribute towards niche differentiation, however future work in understanding the effects of these lake parameters is necessary to determine what influence trophic state has on AOB and AOA niche differentiation.
