## Abstract A new osmotolerant mutant strain of __Zymomonas mobilis__ was successfully used for ethanol production from beet molasses. Addition of magnesium sulfate to hydrolyzed molasses allowed repeated growth without the need of yeast extract addition. The kinetics and yields parameters of ferme
F e d -b a t c h ethanol f e r m e n t a t i o n tests of sugar cane blackstrap molasses were carried out at 32°C and p H 4.5-5.0, using pressed yeast as inoculum, and with no air supply. Two values of the fermentor filling-up time were adopted: 5 h and 7 h. The feeding rates obeyed equation F = F o
