On Reduction of Ammonium Molybdate in Acid
Ammonium molybdate, in acid solution, is reduced to an oxide stage, with the production of a blue color, by many substances of biological importance. Our attention was first attracted to this subject through an accidental observation. We were engaged in the attempt to work out a technique for the nephelometric estimation of phosphoric acid, using a heavy solution of cane sugar for the medium of...
متن کاملOne- and two-electron reduction of molybdate reversibly bound to the archaeal tungstate/molybdate transporter WtpA.
Reversible binding of the tetrahedral oxoanions MoO(4)(2-) and WO(4)(2-) to two carboxylato ligands of the soluble scavenger protein WtpA from the hyperthermophilic archaeon Pyrococcus furiosus enforces a quasi-octahedral MO(6) coordination in which the +VI oxidation state is destabilized.
متن کاملMolybdate Reduction to Molybdenum Blue by an Antarctic Bacterium
A molybdenum-reducing bacterium from Antarctica has been isolated. The bacterium converts sodium molybdate or Mo⁶⁺ to molybdenum blue (Mo-blue). Electron donors such as glucose, sucrose, fructose, and lactose supported molybdate reduction. Ammonium sulphate was the best nitrogen source for molybdate reduction. Optimal conditions for molybdate reduction were between 30 and 50 mM molybdate, betwe...
متن کاملShort Communications Revisiting the role of the electron transport chain in molybdate reduction by Enterobacter cloacae strain 48
Molybdenum reduction to molybdenum blue by microbes is a potential bioremediation tool for molybdenum pollution. A previous work using cyanide as a respiratory inhibitor has shown that the site of molybdenum reduction in Enterobacter cloacae strain 48 is at the electron transport pathway. In the present work, several respiratory inhibitors together with cyanide were used to reinvestigate the si...
متن کاملMolybdate reduction by Escherichia coli K-12 and its chl mutants.
During anaerobic growth, Escherichia coli can reduce phosphomolybdate. The reduction can also be carried out by washed cells suspended in buffer at pH 5.7. Phosphate, molybdate, glucose, cells, and anaerobic conditions are required. Reduction is inhibited by 200 microM chromate, 290 microM nitrite, 10 mM tungstate, or 20 mM cysteine. Wild-type (chl+) cells are inhibited by addition of 200 micro...
