Résumé	Maximum growth of Acetivibrio cellulolyticus in 1% cellobiose (w/v, added as filter sterilized solution) medium was observed after about 24h of incubation at 35°C. The metabolic end products of growth were H2, CO2, acetic acid, ethanol and glucose. Growth was adversely affected if cellobiose was autoclaved with the rest of the media ingredients. In the presence of an excess of cellobiose, the cells accumulated large quantities of an iodophilic polysaccharide (IPS). The maximum IPS accumulation (about 37% of the cell dry weight) was observed after about 12h growth under nitrogen-limiting conditions. Starvation of these cells anaerobically, in a pH 7.0 phosphate buffer for 10 h at 35°C, resulted in about 50% drop in the IPS. The results also indicated that A. cellulolyticus accumulated this iodophilic polysaccharide during growth on cellobiose but not during cultivation on cellulose.
