Therefore, galactose is consumed more slowly than glucose by Saccharomyces cerevisiae (Ostergaard, Olsson, Johnston, & Nielsen, 2000), showing a
diauxic growth pattern, which results in reduced ethanol productivity.
Enzyme production varied depending on carbon source [14] and the variation in carbon sources can change the production of enzyme from extracellular to cell-associated
diauxic growth [15].
The bacterium showed
diauxic growth pattern in medium-A due to the availability of two nutrients, such as thiosulfate first and later tetrathionate, as an intermediate in the culture medium (Tuovinen and Kelly, 1974; Wood and Kelly, 1986; Shooner et al., 1996).
