Fermentation of molasses by Zymomonas mobilis: effects of temperature and sugar concentration on ethanol production.
Fermentations utilizing strains of Zymomonas mobilis, in place of the traditional yeasts, have been proposed due their ethanol yields being close to theoretical. Ethanol production from sugar cane molasses was analyzed under different culture conditions using Z. mobilis in batch fermentation. The total reducing sugars (TRS) concentrations in the molasses, temperature, agitation and culture time...
متن کاملEthanol production by Zymomonas mobilis in fed-batch fermentations.
The production of ethanol by Zymomonas mobilis NRRL B-4286 was studied in fed-batch cultures. Initial percent (w/v) glucose, rate of feed, and quantity of 50%; (w/v) glucose feed were varied. Glucose inhibition of growth rate occurred at concentrations greater than 8% (w/) Feed was begun after 4 h incubation. Feed volume was ca. 36%; of starting batch volume to get ca. 10%; (w/v) ethanol at har...
متن کاملProduction of Acetaldehyde by Zymomonas mobilis.
Mutants of Zymomonas mobilis were selected for decreased alcohol dehydrogenase activity by using consecutively higher concentrations of allyl alcohol. A mutant selected by using 100 mM allyl alcohol produced acetaldehyde at a level of 4.08 g/liter when the organism was grown in aerated batch cultures on a medium containing 4.0% (wt/wt) glucose. On the basis of the amount of glucose utilized, th...
متن کاملProduction of ethanol from starch by co-immobilized Zymomonas mobilis-glucoamylase in a fluidized-bed reactor.
The production of ethanol from starch was studied in a fluidized-bed reactor (FBR) using co-immobilized Zymomonas mobilis and glucoamylase. The FBR was a glass column of 2.54 cm in diameter and 120 cm in length. The Z. mobilis and glucoamylase were co-immobilized within small uniform beads (1.2-2.5 mm diameter) of kappa-carrageenan. The substrate for ethanol production was a soluble starch. Lig...
