Cytosinium hydrogen selenite
In the crystal structure of the title salt, C4H6N3O(+)·HSeO3 (-), systematic name 6-amino-2-methyl-idene-2,3-di-hydro-pyrim-idin-1-ium hydrogen selenite, the hydrogenselenite anions and the cytosinium cations are linked via N-H⋯O, N-H⋯Se, O-H⋯O, O-H··Se and C-H⋯O hydrogen bonds, forming a three-dimensional framework.
متن کاملEnzymatic Reduction of Selenite.
Nickerson, Walter J. (Rutgers, The State University, New Brunswick, N.J.) and Giuseppe Falcone. Enzymatic reduction of selenite. J. Bacteriol. 85:763-771.-1963. Extraction of boiled yeast extract with n-hexane removed its ability to restore selenite-reducing capacity in dialyzed enzyme preparations obtained from baker's yeast or from Candida albicans. Menadione or thiodione substituted for the ...
متن کاملExperimental Study of Hydrogasification of Lignite and Subbituminous Coal Chars
The experimental facility for pressure hydrogasification research was adapted to the pressure of 10 MPa and temperature of 1300 K, which ensured repeatability of results and hydrogen heating to the process temperature. A hydrogasification reaction of chars produced from two rank coals was investigated at temperatures up to 1173 K, pressures up to 8 MPa, and the gas flow rates of 0.5-5 dm(n)(3)/...
متن کاملSelenite and tellurite reduction by Shewanella oneidensis.
Shewanella oneidensis MR-1 reduces selenite and tellurite preferentially under anaerobic conditions. The Se(0) and Te(0) deposits are located extracellularly and intracellularly, respectively. This difference in localization and the distinct effect of some inhibitors and electron acceptors on these reduction processes are taken as evidence of two independent pathways.
متن کاملHigh-sodium Lignite Gasification with the Psdf Transport Gasifier
High-sodium lignite from the Freedom mine in North Dakota was tested in a Transport Gasifier at the Power Systems Development Facility (PSDF). The tests occurred in October 2003 and August 2004 for a total of 445 hours of operation. Due to its high sodium content, the Freedom mine lignite presented unusual challenges to gasifier operations. This paper discusses high-sodium lignite gasification ...
