Award Description: RECOVERY ACT RESEARCH SUPPORT for the Implication of ANAMMOX Community Structure and Microbial Interactions in Estuarine N removal Processes
Project Description: Estuaries along the coastal United States are heavily impacted by nutrient pollution, especially anthropogenic N loading, resulting in the various symptoms of eutrophication and degraded water quality. The intensity and duration of estuarine eutrophication and the rate of estuarine recovery strongly depend on microbial N removal processes (anaerobic ammonium oxidation-ANAMMOX and denitrification). Denitrification has been intensively studied in various estuaries, while ANAMMOX as a recently discovered N removal pathway is much less studied in estuarine ecosystems. ANNAMOX bacteria community structure (abundance and composition) has not been clearly linked to the ANAMMOX rates along estuarine gradients. In addition ANAMMOX community interactions with aerobic ammonia oxidizers and denitrifiers have not been adequately studied to date in estuarine environments. The current project investigates the linkages between microbial community interactions and N removal rates along the environmental gradients of the Cape Fear Estuary, North Carolina. The laboratory work conducted at Queens College is focused upon studies of ammonia oxidizer (AO) community structure and importance of nitrification as a supplier of nitrate and nitrite to N removal processes in estuaries. This study will provide a better understanding of the significance of ANAMMOX in the estuarine N cycle and clarify the interactions between microbial functional groups involved in N-loss from the perspective of microbial diversity, physiology and ecosystem ecology. In addition, the project will provide hands-on training opportunities for students at Queens College in the areas of microbiology and aquatic ecosystem ecology.
