Oxidative phosphorylation in Zymomonas mobilis
Archives of Microbiology, 1993The 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
1991Z. 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.

Capsule formation in Zymomonas mobilis grown on sucrose
World Journal of Microbiology & Biotechnology, 1994A capsule formed around Zymomonas mobilis grown on sucrose, increasing in thickness with higher initial sucrose concentrations. Cryofixation and freeze-substitution electron microscopy techniques preserved this polymer matrix, unlike other techniques.

Cosmeceutical properties of levan produced by Zymomonas mobilis
International Journal of Cosmetic Science, 2006Levan, a polysaccharide that can be produced by both plants and micro‐organisms, is a sugar polymer composed of fructose, with‐2,6 linkages. Here, we have attempted to assess the possible use of levan produced by Zymomonas mobilis as a cosmeceutical ingredient.

Behavior of the IncW plasmid Sa in Zymomonas mobilis
Plasmid, 1987The stability of the broad-host-range IncW R plasmid Sa in Zymomonas mobilis ZM6100(Sa) was monitored using three antibiotic resistance markers carried by Sa. When grown in batch culture without selection, ZM6100(Sa) rapidly lost the Sa plasmid. When grown with selection for either kanamycin or spectinomycin resistance, the three Sa markers were ...

Characterization of the two alcohol dehydrogenases of Zymomonas mobilis
Archives of Biochemistry and Biophysics, 1981Abstract The two alcohol dehydrogenases of Zymomonas mobilis , a fermentative bacterium, have been characterized kinetically and physiologically, and a preliminary biochemical characterization has been made. The two isozymes are separable electrophoretically and have been purified separately by affinity chromatography. One, a tetramer, has a subunit

Metabolic Analysis of Zymomonas mobilis
2000Zymomonas Mobilis is an anaerobic, Gram-negative bacterium producing ethanol from glucose via the Entner-Doudoroff (2-keto-3-deoxy-6-phosphogluconate, KDPG) pathway in conjunction with the enzymes pyruvate decarboxylase and alcohol dehydrogenase. The organism was originally isolated from fermenting sugar-rich plant saps, e.g., in the mexican pulque ...

Genetic Alteration of Zymomonas Mobilis for Ethanol Production
1982Recent interest in ethanol as a potential fuel or fuel supplement has stimulated research into various aspects of the fermentation process. Techniques such as continuous fermentation, vacuum distillation and methods for cell recycle have been investigated (6,10,11), but another important area being studied is that of strain selection and improvement ...

Physiology of Zymomonas mobilis: Some Unanswered Questions
2006The ethanol-producing bacterium Zymomonas mobilis can serve as a model organism for the study of rapid catabolism and inefficient energy conversion in bacteria. Some basic aspects of its physiology still remain poorly understood. Here, the energy-spilling pathways during uncoupled growth, the structure and function of electron transport chain, and the ...
