Development of a Temperature-Phased Anaerobic Digester for Enhanced Conversion of Solids in Animal Manure and Food Wastes to Methane

Methane production by anaerobic digestion is considered on the best methods to generate methane bioenergy, especially from livestock manures and food-processing wastes, however up to 50% of the lignocellulosic solids pass through AD undigested. The objectives of this project are: (1) Develop a temperature-phased anaerobic digester (TPAD) process with enhanced digestion of solids by increasing hydrolysis of lignocellulose in these wastes. (2) Implementation of an integrated research platform consisting of rrs gene sequencing and metagenomics to identify key microbes mediating the TPAD process. (3) Phylogenetic identification of microbes from 3 communities(thermophilic, mesophilic and control) (rrs genes - which microbes are present and which are missing). (4) Identification and characterization of genes encoding hydrolysis of cellulose and other plant polymeric materials.
