During the fermentation of cassava by L. plantarum Z and CL06,
all indicator organisms except B. cereus were inactivated after 48 h
of incubation (7e8 log reduction; Table 4). E. coli was particularly
sensitive to fermentation and was completely inactivated after 24 h
fermentation. In the absence of LAB, B. cereus showed a slight increase
over the observation period, while the other indicator bacteria,
although not showing exponential growth in non-fermenting
cassava, were able to survive and maintain initial population
density.
