Notes:
Summary By enrichment technique, nine anaerobic mixed bacterial cultures were isolated, five of which showed stable cellulolysis. All cultures fermented cellulose and produced different fermentative products. Mixed culture BOC 25 yielded major levels of acetate and ethanol (39.6 and 12.0 mmol/l, respectively) and minor levels of propionate (2.5 mmol/l) and digested filter paper cellulose to the extent of 32.5% w/v. BOC 25 digested cellulosic and lignocellulosic substrates and produced filter paper cellulase, carboxymethyl cellulase, Avicelase and β-glucosidase. Strain DC 25, a cellulolyticClostridium was purified from one of the mixed cultures. The fermentation products of DC 25 from cellulose, cellobiose or glucose were ethanol, acetate, formate, H2 and CO2.
