Abstract
An improved anaerobic digestion of organic biomass by rupturing cells of microorganisms present in a digested biomass or untreated biomass fraction undergoing digestion to obtain a treated biomass fraction having liberated indigenous enzymes in place; and contacting such treated biomass fraction with an untreated biomass fraction so the combined fractions undergo improved anaerobic digestion. The cells in the untreated biomass portion are ruptured by conventional means such as sonication, and about equal volumes of the fractions are preferably combined under conditions of conventional anaerobic digestion.
