Growth and endoglucanase activity of Acetivibrio cellulolyticus grown in three different cellulosic substrates

Abstract

The growth kinetics of Acetivibrio cellulolyticus grown in medium containing different carbon sources (cellobiose, amorphous or crystalline cellulose) was investigated. The specific growth rate was higher in cellobiose fed cultures than in the presence of the other two substrates. Endoglucanase production was greater in cultures grown on amorphous cellulose; enzyme activity increased during the stationary phase in cultures grown on crystalline cellulose.
