Fed-batch cultivation of Cellulomonas on sugarcane bagasse pith.
A high biomass concentration (19.9 g/L) was obtained with the fed-batch cultivation of Cellulomonas on pretreated sugarcane bagasse pith. Similar results in biomass concentration, yield, and substrated consumption were obtained with the discontinuous feed of bagasses as with discontinuous feed supplemented with a partial continuous addition of salts. Two or more growth phases were detected, probably caused by the differential utilization of bagasse components. An acceptably low content of bagasse components remained in the biomass after separation.
