The viable yeast cell count increased from3.94 to 7.09 log CFU/gwet
matter from days 0 to 2, and remained relatively stable thereafter, with
a final cell count of 7.73 log CFU/g wet matter on day 5 (Fig. 1A).
Therefore, days 0 to 2 marked the exponential phase, while days 2 to
5 marked the stationary phase. Untreated (but autoclaved) okara
supported the growth of Y. lipolytica well in SSF setup without any
carbon or nitrogen supplementation.
