Tetrachloroethene (PCE) dehalorespiration was investigated in a continuous coculture of the sulfate-reducing bacterium Desulfovibrio fructosivorans and the dehalorespiring Desulfitobacterium frappieri TCE1 at different sulfate concentrations and in the absence of sulfate. Fructose (2.5 mM) was the single electron donor, which could be used only by the sulfate reducer. With 2.5 mM sulfate, the d...

CodY is a GTP sensor that represses transcription of early stationary phase and sporulation genes in Bacillus subtilis. As nutrients become limiting, GTP levels fall and CodY-mediated repression is relieved. Crystals of CodY have been grown in the presence and absence of GTP from sodium citrate buffered solutions containing lithium sulfate and diffraction data have been collected extending to 3...

Prestin, a member of the solute carrier family 26, is expressed in the basolateral membrane of outer hair cells. This protein provides the molecular basis for outer hair cell somatic electromotility, which is crucial for the frequency selectivity and sensitivity of mammalian hearing. It has long been known that there are abundantly expressed approximately 11-nM protein particles present in the ...

In the title compound, 2C5H12N+·SO42-·2C3H8N2S, the C=S groups of the two independent 1,3-di-methyl-urea mol-ecules and the sulfur atom of the anion lie on twofold axes. The packing is centred on bis-(piperidinium) sulfate ribbons parallel to the c axis; the cations are hydrogen bonded to the sulfate by N-H⋯O and C-H⋯O inter-actions. The 1,3-di-methyl-urea mol-ecules are also hydrogen bonded to...

Lithium minerals become a sub-economic raw material for lithium production to fulfill the demand. This study is about extraction from mica schist using roasting and leaching processes. The located in Kebumen, Indonesia was used phenomena during process. Sodium sulfate as agent while 0.36 M sulfuric acid agent. Solid/liquid ratio (1:5, 1:10, 1:15 1:20 (g/mL)) time (30, 60, 90 120 minutes) were v...

Lithium has been a mainstay for the treatment of bipolar disorder, yet the molecular mechanisms underlying its action remain enigmatic. Bisphosphate 3'-nucleotidase (BPNT-1) is a lithium-sensitive phosphatase that catalyzes the breakdown of cytosolic 3'-phosphoadenosine 5'-phosphate (PAP), a byproduct of sulfation reactions utilizing the universal sulfate group donor 3'-phosphoadenosine 5'-phos...

Metalation of an ammonium tris(phenol) ligand affords new lithium/sodium derivatives having central pseudocubane motifs in which one of the metallic positions is replaced by a four-coordinate hydrogen atom.

We studied thermophilic sulfate reduction with methanol as electron donor in continuous cultures. Mixed cultures of selected microorganisms were used, representing different methanol degrading pathways followed by various trophic groups of microorganisms. Our results show that direct competition for methanol between a homoacetogen, Moorella thermoautotrophica, and a sulfate reducer, Desulfotoma...
