Alcohol dehydrogenase isoenzymes nomenclature.
We read with a great pleasure the article ‘Rare ADH variant constellations are specific for alcohol dependence’ by Zuo et al. (2012). We want to direct the speciality about the alcohol dehydrogenase (ADH) isoenzyme nomenclature to the readers of Alcohol and Alcoholism. Namely, the authors use an old isoenzyme nomenclature what can cause some confusion to not enough familiar readers. Electrophor...
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 کاملDifferential Expression of Zymomonas mobilis Sucrase Genes (sacB and sacC) in Escherichia coli and Sucrase Mutants of Zymomonas mobilis
The sacB and sacC genes encoding levansucrase and extracellular sucrase respectively were independently subcloned in pBluescript (high copy number) and in Z. mobilis-E. coli shuttle vector, pZA22 (low copy number). The expression of these genes were compared under identical background of E. coli and Z. mobilis host. The level of sacB gene expression in E. coli was almost ten fold less than the ...
متن کاملGlycolytic enzymes in Zymomonas mobilis.
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...
متن کاملEnhancement of furan aldehydes conversion in Zymomonas mobilis by elevating dehydrogenase activity and cofactor regeneration
BACKGROUND Furfural and 5-hydroxymethylfurfural (HMF) are the two major furan aldehyde inhibitors generated from lignocellulose dilute acid pretreatment which significantly inhibit subsequent microbial cell growth and ethanol fermentation. Zymomonas mobilis is an important strain for cellulosic ethanol fermentation but can be severely inhibited by furfural and (or) HMF. Previous study showed th...
