At 72 h, LAB represented approximately 17% of the total bacterial population
and at the completion of fermentation (144 h), they were 100%.
The growth of LAB during fermentation of these beans was inhibited
by the addition of nisin, but such nisin did not affect the total populations
of yeasts and other bacteria (Fig. 1b). Also, nisin did not affect
the growth profiles of individual species of yeasts (Fig. 1c, d) and acetic
acid bacteria (Fig. 1e, f).
