The changes in the growth pattern of the Saccharomyces cerevisiae strains obtained from palm wine and baker’s yeast are shown in Figure 4. The results reveal that there was a gradual increase in the cell growth of the yeast strains in both varieties of cassava used with increase in concentration of hydrolysate. However, the utilization of the different hydrolysates generally decreased after 48 h showing gradual decline at 72 h with different optical densities.
