Abstract

Corn cobs were treated at room temperature with NaOH at a ratio of 100:3 (w/w), but with different volumes of water from 3 to 0.25 ml/g corn cob. The biomasses obtained from a mixture culture of Cellulomonas sp. and Bacillus subtilis under each condition were similar (5.5 to 6.0 g/l) and protein only varied between 30% and 40% (w/w biomass) or 1.9 and 2.2 g/l. Low volumes and low amounts of NaOH can therefore be used in a cost-effective manner.
