Table 3 - Influence of various fermentation variables on exo-glucanase production in Cellulomonas flavigena

Table 3. Effect of addition of glucose to a-cellulose medium (containing 0.4% sodium nitrate in Dubos medium) on cellobiohydrolase formation parameters. Each value is a mean of three replicates. ± stands for standard deviation among replicates. Means followed by different letters within each column differ significantly at r <= 0.05 using one factor factorial design in MStatC software.
