The objective of this project is to find biological methods to remove carboxylic functionalities from low rank coals under ambient conditions and to assess the properties of these modified coals towards coal decarboxylation. The microbial consortia will be developed using a fermentor system first under batch and then in a continuous system. The main objectives for this quarter were to develop microbial consortia that would decarboxylate coal and isolate potential anaerobic microorganisms with decarboxylating, ability from these enriched microbial consortia, to continue to compare the known cultures with reward to their ability to decarboxylate coal, and to characterize the anaerobically biotreated coal using FTIR to confirm decarboxylation of coal. Significant achievements during the period include: coal decarboxylation was possible only under anaerobic conditions. microbial consortia that can anaerobically decarboxylate coal have been developed using anaerobic vials and batch fermentor system, and loss of carboxyl groups in biotreated coal has been confirmed by FT-IR.
