β¦ Synopsis
Batch fermentations of sugar-cane blackstrap molasses to ethanol, using pressed yeast as inoculum, demonstrated an exponential relationship between the time necessary to complete the fermentation and the initial concentrations of sugar and yeast cells. The parameters of the derived exponential equations depended on the experimental conditions.

Multiparameter flow cytometric techniques developed in our laboratories have been used for the "atline" study of fed-batch bacterial fermentations. These fermentations were done at two scales, production (20 m 3 ) and bench (5 Γ 10 -3 m 3 ). In addition, at the bench scale, experiments were undertak
