    Notes:
    Abstract The nutritional and physiological factors affecting sporulation of Clostridium cellulolyticum were studied using steady-state continuous cultures grown in both complex and synthetic media. Under cellobiose limitation, the probability that cells will sporulate appears to be directly related to the growth rate. In complex medium, the highest percentage of sporulation was 20% at a dilution rate of 0.015 h−1 whereas in synthetic medium it was 10% at 0.035 h−1. In both media, when the dilution rate was either higher or lower the percentage of sporulation decreased by between 2% and 4%. At low dilution rates, endospore formation was repressed under cellobiose-sufficient concentrations, suggesting catabolite repression by cellobiose. Furthermore, the concentration of ammonium was important in determining the percentage of sporulation, as ammonium limitation induced extensive sporulation at low growth rates even in an excess of cellobiose. The sporulation process is not triggered when cells are cellobiose-exhausted both in complex and synthetic media. These data suggest that, in C. cellulolyticum, an exogenous supply of carbon is required throughout the sporulation process. In the experimental conditions used in this work, no relationship between glycogen accumulation or glycogen mobilization and endospore formation was detected in C. cellulolyticum.
