In addition the enzyme catalyzes the oxidation of NADH by 0 2 . The stoichiometry of the first reaction is proved by the formation of the amount of NADH which under anaerobic conditions exactly corresponds to the amount of formate used. In this reaction NAD is replaceable by a large number of redox dyes. For the second reaction the stoichiometry is proved a) kinetically by the relation of the v...

The ability of Shewanella decolorationis S12 to obtain energy for growth by coupling the oxidation of various electron donors to dissimilatory azoreduction was investigated. This microorganism can reduce a variety of azo dyes by use of formate, lactate, pyruvate, or H(2) as the electron donor. Furthermore, strain S12 grew to a maximal density of 3.0 x 10(7) cells per ml after compete reduction ...

This experiment was carried out to evaluate the possibility of degradation of d-lactate into formate and acetaldehyde. In order to induce hyperproduction of d-lactate in rats. Donryu male albino rats were fed diets containing 0.064% 3'-methyl-4-dimethylaminoazobenzene (3'-MDAB), 4'-methyl-4-dimethylaminoazobenzene (4'-MDAB) or 2-methyl-4-dimethylaminoazobenzene (2-MDAB) for 10 weeks. During the...

The reduction of CO2 in a biphasic liquid-condensed gas system was investigated as a function of the CO2 pressure. Using 1-benzyl-1,4-dihydronicotinamide (BNAH) as sacrificial electron donor dissolved in a dimethylformamide-water mixture and [Ru(bpy)2(CO)L](n+) as a catalyst and [Ru(bpy)3](2+) as a photosensitizer, the reaction was found to produce a mixture of CO and formate, in total about 25...

tio2 nanoparticles were synthesized by modified sol—gel method using pure room temperature ionic liquid(rtil) 2-hydroxyethylammonium formate as a reaction medium. the structure and morphology of tio2nanoparticles were characterized with x-ray powder diffraction (xrd), bet surface analysis and scanningelectron microscopy (sem). tio2 nanoparticles were synthesized in open and closed vessels. the ...

The asymmetric unit of the title compound, [Co(HCO(2))(2)(C(14)H(12)N(2))(H(2)O)]·H(2)O, contains a mononuclear complex mol-ecule hydrogen bonded to a lattice water mol-ecule. The Co(II) cation is in a distorted octa-hedral coordination environment defined by the two N atoms of the 2,9-dimethyl-1,10-phenanthroline ligand and four O atoms. Two of these are from a chelating formate anion, one fro...

In the title compound, {[Fe(CHO(2))(2)(C(10)H(8)N(2))(H(2)O)]·4H(2)O}(n), the Fe(II) ion is coordinated by two 4,4'-bipyridyl (4,4'-bpy) ligands, three formate ligands and one water molecule. The slightly distorted octahedral FeN(2)O(4) coordination results from the N atoms of two bridging 4,4'-bpy ligands, the O atoms of two bridging HCOO(-) anions of anti-anti mode, all in trans positions aro...

Role of one-carbon precursors in the biosynthesis of deoxyribonucleic acid in bacteriophage-infected and growing cells of Escherichia coli. J. Bacteriol. 82:867-874. 1961.-The ability of growing and T2 bacteriophage-infected cells of Escherichia coli to incorporate serine-3-C(14), glycine-2-C(14), formate-C(14), ...

The asymmetric unit of the title compound, [Ni(HCO(2))(2)(C(14)H(12)N(2))(H(2)O)]·H(2)O, contains a mononuclear complex mol-ecule hydrogen bonded to a lattice water mol-ecule. The Ni(II) atom exhibits a distorted octa-hedral coordination geometry formed by the N atoms from a 2,9-dimethyl-1,10-phenanthroline ligand, two O atoms of a chelating formate anion, one aqua O atom and one O atom of a co...
