Three short-chain alcohol dehydrogenases from Burkholderia gladioli were discovered for their great potential in the dynamic kinetic asymmetric transformation of methyl 2-benzamido-methyl-3-oxobutanoate, and their screening against varied organic solvents and substrates. This is the first report of recombinant enzymes capable of achieving this reaction with the highest enantio- and diastereo-se...

In the hydroxylation of the methyl group of p-cresol by an enzyme from Pseudomonas putida the oxygen atom is derived from water. Although a second reaction by the same enzyme converts the product, p-hydroxybenzyl alcohol, into the aldehyde, the alcohol is an enzyme-free intermediate.

In a former communication* the use of alcohol was proposed as a basis for a very rapid means of determining the moisture content of soils and possibly of other materials. Th~ form of alcohol that was then suggested was ethyl alcohol. In order to ascertain whether there are other liquids that would be more satisfactory than ethyl alcohol, an investigation has been conducted in which a large numb...

Individual poly(methyl methacrylate)/MWCNT doped with sulfuric acid were polymerized in situ to yield individual nanotubes increased electrical conductivity. In the presence of aliphatic alcohol vapors various diameters, Nanocomposites measured as a function time. These sensor responses are particularly rapid due huge surface volume ratio, consistent diameter, and limited amount active material...

Alcohol dependence is a chronically relapsing disorder characterized by compulsive drug seeking and drug taking, loss of control in limiting intake, and the emergence of a withdrawal syndrome in the absence of the drug. Accumulating evidence suggests an important role for synaptic transmission in the central amygdala (CeA) in mediating alcohol-related behaviors and neuroadaptative mechanisms as...

Abstract Furans are an important class of compounds that can be thermochemical or enzymatically produced from biomass. Despite their importance little is known about the thermal decomposition furans with oxygenated substituents. In this work, influence -CH3, -CH2OH and -CHO functional groups on molecular radical chemistry studied a combined quantum chemical experimental approach using 2-furfury...

The yeast Yarrowia lipolytica is well known for its versatile production of metabolites from various substrates, but, although isolated from, e.g., wild-fermented Belgian Sour beers, it rarely considered a starter culture in fermented beverages. In this study, we aimed to elucidate the ability Y. ferment brewers’ wort containing iso-α-acid 7 days at low and high aeration 20 °C 30 °C, with speci...

The rheological response of blends obtained from quaternized polysulfone and polyvinyl alcohol in N-methyl-2pyrrolidone as against structural peculiarity of polymers from the blend, composition of polymer mixtures, as well as the types of interactions were investigated. Results show that the variation of polyvinyl alcohol composition in the studied system determines changes of the rheological p...

Model studies in mice indicate that the severity of alcohol withdrawal is associated with polymorphic variation and expression of the MPDZ gene. Current knowledge about variation in the human MPDZ gene is limited; however, our data indicate its potential association with alcohol dependence. The multi-PDZ protein is an important part of the N-methyl-D-aspartate (NMDA)-dependent α-amino-3-hydroxy...
