Fructose metabolism in Zymomonas mobilis

Applied Microbiology and Biotechnology, 1986
In the metabolism of fructose by Zymomonas, the ethanol yield is decreased due to the formation of dihydroxyacetone, mannitol and glycerol. The reduction of fructose to mannitol by an NADPH-dependent mannitol dehydrogenase is apparently coupled to the oxidation of glucose-6-phosphate by glucose-6-phosphate dehydrogenase, which exhibits higher activity ...

Metabolism of galactose in Zymomonas mobilis

Applied Microbiology and Biotechnology, 1991
Zymomonas mobilis IFO 13 756 could take up galactose and metabolize it so that galactonic acid accumulated in the culture fluid. The oxidation of galactose was catalysed by a membrane-associated enzyme, which could be solubilized with a mixture of 1% Triton X-100 and 1 M: KC1. The strain also accumulated galactitol as a minor metabolite.

Oxidative phosphorylation in Zymomonas mobilis

Archives of Microbiology, 1993
The obligately fermentative aerotolerant bacterium Zymomonas mobilis was shown to possess oxidative phosphorylation activity. Increased intracellular ATP levels were observed in aerated starved cell suspension in the presence of ethanol or acetaldehyde. Ethanolconsuming Z. mobilis generated a transmembrane pH gradient.

Byproducts from Zymomonas mobilis

1991
Z. mobilis is a microorganism that is not only an extremely efficient producer of alcohol, but also is capable of producing other metabolites in high concentrations under the correct culture conditions. The technology exists to manufacture fructose, sorbitol and gluconic acid at high yields and rates; all three are valuable chemicals.

Sorbitol production using recombinant Zymomonas mobilis strain

Journal of Biotechnology, 2010
A recombinant Zymomonas mobilis strain harboring the plasmid pHW20a-gfo for over-expression of glucose-fructose oxidoreductase (GFOR) was constructed. The specific activity of GFOR enzyme in the new recombinant strain was at least two folds greater than that in the wild strain.

Sorbitol production by Zymomonas mobilis

Applied Microbiology and Biotechnology, 1984
High resolution 13C Nuclear Magnetic Resonance (NMR) spectroscopy has been employed to determine the chemical composition of the unknown major products in a sucrose or fructose plus glucose fermentation to ethanol by the bacterium Zymmonas mobilis. When grown on these sugars Z.mobilis was found to produce significant amounts of sorbitol, up to 43 g·l-1

Zymomonas mobilis—Towards Bacterial Biofuel

2017
Bioconversion of lignocellulosic hydrolysates to ethanol is a promising solution to energy from renewable non-food sources. While utilisation of all sugars in these hydrolysates by Zymomonas mobilis has been facilitated through genetic modification of this organism, and molecular biology and fermenting capabilities of xylose-utilising Z.

Zymomonas Mobilis—Science and Industrial Application

Critical Reviews in Biotechnology, 1993
Zymomonas mobilis is undoubtedly one of the most unique bacterium within the microbial world. Known since 1912 under the names Termobacterium mobilis, Pseudomonas linderi, and Zymomonas mobilis, reviews on its uniqueness have been published in 1977 and 1988.

Zymomonas mobilis cell viability: measurement method comparison

Antonie van Leeuwenhoek, 1993
Comparison of three different cell viability methods: slide count, plate count and methylene blue staining techniques, applied on Zymomonas mobilis cultures, was performed. The slide technique proved to be faster and more accurate than the plate count method, and both of them far more reliable than the standard methylene blue method which constantly ...
