Ghosh, S

Acid-phase fermentation is a key step in biomass-to-methane conversion by anaerobic digestion, and it assumes special importance owing to its capability to produce various organic acids (industrial intermediates) that could be feeds for hydrocarbon fuel production. This research was concerned with: (1) acidogenic fermentation of a simple and a complex substrate; (2) the development of kinetic models describing product formation rate and efficiency as functions of common process control variables and kinetic constants; and (3) the determination of kinetic constants for glucose and sludge digestion. The benefits of organism and substrate concentration and recycling are emphasized.
