BIOMASS PRODUCTION FROM ELECTRICAL PLANT FLUE GAS
Forage-Animal Production Research
2009 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.
Performance of this agreement is monitored by USDA-ARS, Forage Animal Production Research Unit (FAPRU) scientists being closely involved as collaborators in the agreement project, and meeting with the collaborator on an as needed basis to alter experimental design. Information exchange and planning is via face to face meetings, teleconferences or email on a regular basis. The objectives of this agreement are: Set up an anaerobic microbiology laboratory at the University of Kentucky’s Center for Applied Energy Research (CAER) and to train personnel to perform microbiological experiments related to the project. Along these lines CAER personnel spent three weeks working in the USDA-ARS-FAPRU rumen microbiology lab under the unit’s research microbiologist tutelage. The personnel have returned to CAER to begin purchasing equipment and setting up space. Consultation is ongoing.
