Roles of acid-producing bacteria in anaerobic digestion of waste activated sludge
Next Previous
Abstract
Three acid-producing strains were isolated and identified. The isolated bacteria accelerated the anaerobic digestion processes. Bacillus coagulans improved TCOD removal, VS removal and biogas production. The optimal inoculum concentration of Bacillus coagulans AFB-1 was 30%.
