Zymomonas mobilis as a model system for production of biofuels and biochemicals
Zymomonas mobilis is a natural ethanologen with many desirable industrial biocatalyst characteristics. In this review, we will discuss work to develop Z. mobilis as a model system for biofuel production from the perspectives of substrate utilization, development for industrial robustness, potential product spectrum, strain evaluation and fermentation strategies. This review also encompasses per...
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 biofuels and biochemicals: in need of an ORACLE.
The engineering of cells for the production of fuels and chemicals involves simultaneous optimization of multiple objectives, such as specific productivity, extended substrate range and improved tolerance - all under a great degree of uncertainty. The achievement of these objectives under physiological and process constraints will be impossible without the use of mathematical modeling. However,...
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...

Raps, Shirley (University of Illinois, Urbana) and R. D. DeMoss. Glycolytic enzymes in Zymomonas mobilis. J. Bacteriol. 84:115-118. 1962-An enzyme extract of Zymomonas mobilis (Pseudomonas lindneri) was capable of fermenting glucose-6-phosphate to CO(2) and ethanol. The extract was found to contain phosphohexoisomerase, aldolase, and glyceraldehyde-3-phosphate dehydrogenase, but no demonstrable...
