(Microbial ecology of thermophilic anaerobic digestion): (Progress report, Year 4)
The goal of this project is to gain a more complete understanding of the microorganisms converting a lignocellulose waste to methane in a thermophilic (58/degree/C) anaerobic bioreactor. We have directly examined microbial populations in the bioreactor and have examined the properties of microorganisms isolated from the bioreactor. The primary focus has been on anaerobic thermophiles involved in the formation and degradation of acetic acid, the precursor of two-thirds of the methane produced in the bioreactor. Also, novel organisms of fundamental and practical significance have been isolated and characterized.
