Global steady-state optimization of Zymomonas mobilis fermentation process problems is performed to demonstrate the existence of multiple optimum solutions necessitating the use of a global optimization strategy. It is shown that the steady-state equations for the Zymomonas mobilis fermentation process can be reduced to a single equation which when used as a constraint results in yielding only one optimum solution, the global one.
SummaryPrevious studies have demonstrated that Zymomonas mobilis is a very promising organism for ethanol production. In the present study comparative kinetic data from batch and continuous cultures on glucose media are presented which show that a new strain of Z. mobilis has higher specific rates of growth and ethanol production as well as a higher tolerance to ethanol.
