Objectifs
Objective 1. Functional genomics of nitrifying bacteria. Supply genomic DNA of selected nitrifying bacteria for draft-level and complete genome sequencing. Work with the Joint Genome Institute and the DOE to facilitate genome sequencing and analysis. Annotate and check functional designations for selected genes especially those encoding enzymatic functions. Perform comparative genome analysis on nitrifying bacteria sequenced. Write collaborative papers. Objective 2. Ecology of nitrification in agricultural systems in the Intermountain West. Collaborate in ongoing agricultural systems experiments comparing conventional and organic fertility management for effects on nitrification. Objective 3. Ecology of nitrification in wildland systems in the Intermountain West. Collaborate in ongoing experiments in wildland systems examining plant species diversity and function to assess nitrifier functional diversity and ecology of nitrification. This area of research will require establishment of collaborative relationships, site assessment and selection and the collection of baseline data on nitrification in a variety of ecosystems in Colorado and Utah. Objective 4. Characterization of N cycling in wastewater treatment systems. Explore wastewater N cycle in selected wastewater treatment systems in Utah. Assess the key microbial communities, specifically ammonia oxidizing bacteria and archaea by the application of molecular tools waste treatment systems. Determine rate parameters for nitrification in lagoon, artificial wetland, and storage pond environments. Identify key vulnerability points of the N cycling processes needed to maintain effluent water quality
