What is the ethanol production rate of Zymomonas?
What is the ethanol production rate of Zymomonas?
High density fermentation and cell recycling produced metabolic yield of 87.8–94.5% and ethanol productivity of 1.70–1.89 g L–1 h–1, which showed superior performance as compared to traditional fermentation with metabolic yield of 79.5% and productivity of 0.46 g L–1 h–1 (Figure 5A).
Where is Zymomonas mobilis found?
Zymomonas mobilis is a rod shaped gram-negative bacterium that can be found in sugar rich plant saps. It is usually 2-6 μm long and 1-1.4 μm wide, but this can vary significantly. In high CO2 or ethanol concentrations slime and granular layers have been seen around the cell.
What is the best feedstock to produce the most liquid ethanol?
Corn
Starch- and Sugar-Based Ethanol Feedstocks Corn is the leading U.S. crop and serves as the feedstock for most domestic ethanol production. Corn ethanol meets the renewable fuel category of the Renewable Fuel Standard (RFS), which is limited to 15 billion gallons.
What are the advantages of Zymomonas mobilis over Saccharomyces cerevisiae in ethanol production?
As a candidate bio-ethanol producer, Zymomonas mobilis showed some advantages, for example, higher specific rate of sugar uptake, high ethanol yield, lower biomass production, non-requirement of controlled addition of oxygen during fermentation, et cetera [8–13].
Is zymomonas a yeast?
It is the only species found in the genus Zymomonas. It has notable bioethanol-producing capabilities, which surpass yeast in some aspects….

What is the advantage of using yeast and Zymomonas during fermentation?
1. What is the advantage of using either yeast or Zymomonas during fermentation? a. Zymomonas and yeast generate a mixture of products, whereas other microorganisms only produce alcohol.
Is Zymomonas mobilis a yeast?
Zymomonas mobilis is a Gram negative, facultative anaerobic, non-sporulating, polarly-flagellated, rod-shaped bacterium. It is the only species found in the genus Zymomonas. It has notable bioethanol-producing capabilities, which surpass yeast in some aspects.
