1. A process comprising:
anaerobically degrading a biomass selected from the group consisting of sewage, agricultural waste products, brewery grain by-products, food waste, forestry waste, crops, grass, seaweed, plankton, algae, fish, fish waste, corn, potato waste, sugar cane waste, sugar beet waste, straw, paper waste, chicken manure, cow manure, hog manure, switchgrass and combinations thereof by fermentation in an enclosed bioreactor in the presence of a marine Thermotoga species at a NaCl concentration of less than 0.2%, a redox potential of from −125 to −850 mV, and a cell density of at least 1×109 cells/ml, then
introducing a nondeoxygenated biomass into the degraded biomass in the enclosed bioreactor and fermenting the nondeoxygenated biomass to produce hydrogen and a slurry comprising biomass residue and acetate,
pumping said slurry into a methane bioreactor to produce biogas in a second fermentation process, and
removing the biogas from the methane bioreactor.
