On the other hand, 30 C incubation was superior to 37 C incubation
for the production of the fibrinolytic enzyme based on the
observation that the highest fibrinolytic activity was obtained for
30 C/120 h/stirred red bean fermentation (Table 2). Because
fibrinolytic activity was considered to be the most desirable
bioactivity in fermented red beans, 30 C was selected as the optimum
fermentation temperature. The 30 C-fermented red bean
culture contained a high biomass of both bacteria, even though it
had fewer viable cells of L. bulgaricus than that for red beans fermented
at 37 C.
