Pathways of initial oxidation of n-alkanes were examined in two strains of Cladosporium resinae. Cells grow on dodecane and hexadecane and their primary alcohol and monoic acid derivatives. The homologous aldehydes do not support growth but are oxidized by intact cells and by cell-free preparations. Hexane and its derivatives support little or no growth, but cell extracts oxidize hexane, hexano...

The reactivity of the electro-oxidation products N-hydroxyphthalimide (NHPI) with an aromatic alcohol, 4-methoxybenzyl alcohol (MBA) in a sulfuric acid-acetonitrile mixed solution was investigated. Phthalimide N-oxyl radical (PINO·), which is produced by one-electron oxidation NHPI, reacted MBA as well aprotic solvent. Further PINO· also but results showed complex-shaped voltamograms.

Photocatalytic oxidation of benzyl alcohols in aqueous suspensions of rhodium ion-modified titanium(iv) oxide (Rh(3+)/TiO2) in the presence of O2 under irradiation of visible light was examined. In the photocatalytic oxidation of benzyl alcohol, benzaldehyde was obtained in a high yield (97%) with >99% conversion of benzyl alcohol. Rh(3+)/TiO2 photocatalysts having various physical properties w...

alcohol oxidation is an important reaction in organic syntheses. some of these reactions must beunder difficult conditions in respect of high temperature and pressure. in many cases, reactions areconducted by environmentally in appropriate solutions. in this study, preparing an effectivenanocatalyst and estimating the optimum provisions of its production processes are assessed. twomajor and cru...

Previous reports on the enzymic activities of lactic acid bacteria have shown the presence of alcohol dehydrogenases in several strains of streptococci (Gunsalus and Wood, 1942). The presence of this enzyme system in orgams generally characterized by a pure lactic acid fermentation is perhaps somewhat unexpected, and may indicate a wider distribution of alcohol enzymes than is generally realize...

The effect of alcohol on overnight energy expenditure and substrate disposal was studied in eleven subjects (five men, six women) using whole-body indirect calorimetry for 15.5 h after test meals. Three test meals were studied in random order with at least 48 h between treatments: control, 50% of maintenance energy needs provided as 14, 40 and 46% energy from protein, fat and carbohydrate respe...

It is shown that the unusual NAD(P)+-independent quinoprotein alcohol dehydrogenase, said previously to be responsible for oxidation of ethanol during growth of Acinetobacter calcoaceticus LMD 79.39, was in fact isolated from an unidentified organism which contained cytochrome c and which has now been lost. Several genuine strains of A. calcoaceticus do not contain cytochrome c nor do they cont...

The vanadium-based catalyst, acts as a homogeneous catalyst for the selective oxidation of various kinds of sulfides with 30% aqueous H2O2. Vanadium-based catalyst was successfully used as the oxygen source for the oxidation of sulfides to sulfoxides for the first time. The sulfoxides were obtained in a good way to high yields without any detectable over-oxidation to sulfones under normal condi...

Palladium nanoparticles supported on multi-walled carbon nanotubes (Pd/MWCNTs) have been synthesized using a modified polyol reduction method and its performance in methanol oxidation reactions has evaluated. The morphology of palladium on MWCNTs was characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The catalytic performance of synthesized catalyst ...
