The effects of temperature and inlet pH of the medium on the ethanol productivity and activity of the immobilized Z. mobilis cells during continuous fermentation of glucose have been studied at various temperatures and pH. On changing the temperature from one steady state level to a new one, 6-8 h w

Zymomonas mobilis, strain ATCC 10988, was used to evaluate the effects of pH (5.0 to 8.0), temperature (30ยฐC to 40ยฐC), and initial glucose concentration(75 g/C to 150 g/6) on the kinetics of ethanol production from glucose using batch fermentation. Specific ethanol production rate was maximum and ne
The inclusion of specific salts in Zymomonas mobilis batch sucrose fermentations can limit by-product formation. Sorbitol and fructo-oligosaccharide formation can be reduced and ethanol production enhanced by manipulating mineral salt concentrations. Chloride salts reduced the production of biomass
