2010 Annual Report

1a. Objectives (from AD-416)
Objective 1: Set up an anaerobic microbiology laboratory at the University of Kentucky’s Center for Applied Energy Research (CAER). Objective 2: Hire and train personnel to perform microbiological experiments related to the project. Objective 3: Produce biomass products from electrical plant flue gas. Objective 4: Evaluate products as ruminant feed/feed additives.

1b. Approach (from AD-416)
Carbon dioxide will be captured from power plant flue gas with an ammonium stripper. The resulting ammonium carbonate solution will be used as a growth substrate for microorganisms. Photosynthetic organisms will be cultured in a photoreactor. Fermentative organisms will be cultured in anaerobic batch. Materials will be separated from the photoreactor and fermentation products, and these materials will be evaluated as feed additives for ruminants. All research will be funded and performed by CAER, and ARS will act in an advisory capacity. In years 4 and 5, we anticipate having consistent biomass products derived from flue gas carbon dioxide. These products will be evaluated as feed for ruminants.

3. Progress Report
A laboratory was set up at the Center for Applied Energy Research. A pilot-scale nitrifying bioreactor was constructed. Performance of this agreement is monitored by USDA-ARS, Forage-Animal Production Research Unit scientists being intimately involved as collaborators in the agreement project, and calling, emailing, or meeting with the collaborator on an as needed basis to alter experimental design.
