The effectiveness of Microbiologically Induced Carbonate Precipitation (MICP) from the formate oxidation by Methylocystis parvus OBBP as an alternative process for concrete protection was investigated. MICP was induced on Autoclaved Aerated Concrete (AAC), the model material, by immersing the material in 10(9) M. parvus cells mL(-1) containing 5 g L(-1) of calcium formate. A 2 days immersion of...

Potassium formate, the potassium salt of formic acid, is an inexpensive, non-corrosive, non-toxic, and bio-degradable desiccant that has not been considered thus far in atmospheric water harvesting applications.ster proposed utilizes aqueous solution formate as medium for moisture absorption during night when ambient relative humidity high, desorption absorbed from day using solar energy. A sim...

The ruthenium hydride [RuH(CNN)(dppb)] (1; CNN = 2-aminomethyl-6-tolylpyridine, dppb = 1,4-bis(diphenylphosphino)butane) reacts rapidly and irreversibly with CO2 under ambient conditions to yield the corresponding Ru formate complex 2. In contrast, the Ru hydride 1 reacts with acetone reversibly to generate the Ru isopropoxide, with the reaction free energy ΔG°(298 K) = -3.1 kcal/mol measured b...

5-fluoropyrimidine (2-HFP) were measured on Sarcoma 180 ascites cells. A marked extension of the life-span of tumor-bearing mice was afforded by i.p. injections of 5-FU, whereas both 4-HFP and 2-HFP were only weakly active. Sarcoma 180 ascites cells converted both 4-HFP and 5-FU into mono-, di-, and trinucleotide forms of 5-FU and incorporated the 5-fluoropyrimidines into RNA exclusively as 5-F...

This review provides an overview of advances on constructing heterogeneous nanostructured and single atom catalysts for CO2 hydrogenation to formic acid/formate. The main focus is placed structure–activity correlations mechanistic insights.

In the structure of the title compound [Fe(2)(C(5)H(5))(2)(CHO(2))(CO)(4)]BF(4), each Fe(II) atom is coordinated in a pseudo-octa-hedral three-legged piano-stool fashion. The cyclo-penta-dienyl ligand occupies three fac coordination sites while the two carbonyl ligands and formate O atom occupy the remaining three sites.

Bicarbonate (HCO3-) causes a significant and reversible stimulation of anion-inhibited electron flow in photosystem II of higher plants and cyanobacteria. To test if selected arginine (Arg) residues are involved in the binding of HCO3-, we utilized oligonucleotide-directed mutagenesis to construct Synechocystis sp. PCC 6803 mutants carrying mutations in Arg residues in the D2 protein. Measureme...

Helicobacter pylori produces one monofunctional catalase, encoded by katA (hp0875). The crystal structure of H. pylori catalase (HPC) has been determined and refined at 1.6 A with crystallographic agreement factors R and R(free) of 17.4 and 21.9%, respectively. The crystal exhibits P2(1)2(1)2 space group symmetry and contains two protein subunits in the asymmetric unit. The core structure of th...

There are many indications that vitamins containing p-aminobenzoic acid (PABA) are concerned with the synthesis of a variety of metabolites (l-16). The mode of action of the PABA-containing vitamins is suggested by the work of Shive et al. (ll), who found that the amine which accumulates in sulfanilamide-treated Escherichiu coli (12) is 5-amino-4-imidazolecarboxamide. The addition of only a sin...
