Abstract:

Electrospray tandem mass spectrometry was used to determine steady-state serum and urinary inorganic sulfate and sulfate ester kinetic profiles of nine normal men after intravenous injection of the stable isotope sodium [34S]sulfate. Sulfate ester appearance was traced by eliminating inorganic sulfate from samples, followed by hydrolysis of sulfate esters to inorganic sulfate for analysis. Whole body inorganic sulfate turnover in steady state was calculated using standard tracer techniques. Rate of appearance and disappearance of inorganic sulfate was 841 ± 49 μmol/h. Average urinary inorganic

Abstract:

Laboratory microcosms were used to investigate rates of S movement into and out of sediments and factors affecting its net retention and speciation. Rates of sulfate reduction, calculated from movement of 35S into and out of the sediments, were much higher than net rates of sulfate movement into the sediments. Results suggested that high rates of sulfide oxidation accompanied high rates of sulfate reduction; net flux across the interface depended on the balance between these two processes. Both pyrite and acid-volatile sulfides were dynamic pools undergoing rapid formation and oxidation. Measu

Abstract:

Abstract A number of flavonoid 3′,4′-disulfates were synthesized from the corresponding 4′-sulfate esters, using sulfur trioxide-trimethylamine complex. Desulfation of the sulfate esters using aryl sulfatase demonstrated that the rate of hydrolysis of the 3′-sulfate group was slower than either the 7- or 4′ groups, thus allowing the specific synthesis of flavonol 3,3′-disulfates. The effects of ortho-disulfation on the 13C NMR spectra of flavonoids, and the regative FAB-MS spectra of diand trisulfated flavonoids are discussed.

Abstract:

ABSTRACT The sulfur present in both agricultural and uncultivated soils is largely in the form of sulfonates and sulfate esters and not as free, bioavailable inorganic sulfate. Desulfurization of the former compounds in vitro has previously been studied in Pseudomonas putida, a common rhizosphere inhabitant. Survival of P. putida strains was now investigated in three sulfur-deficient Danish soils which were found to contain 60 to 70% of their sulfur in sulfonate or sulfate ester form, as determined by X-ray near-edge spectroscopy. The soil fitness of P. putida S-313 was compared with that of i

Leizhou Peninsula in South China is facing a serious water shortage problem because of the special regional and geological conditions. As a kind of low water requirement crop, pineapple has been popular in lateritic soil.

ABSTRACT A gene cluster upstream of the arylsulfatase gene (atsA) in Pseudomonas aeruginosa was characterized and found to encode a putative ABC-type transporter, AtsRBC. Mutants with insertions in the atsR oratsB gene were unable to grow with hexyl-, octyl-, or nitrocatecholsulfate, although they grew normally with other sulfur sources, such as sulfate, methionine, and aliphatic sulfonates. AtsRBC therefore constitutes a general sulfate ester transport system, and desulfurization of aromatic and medium-chain-length aliphatic sulfate esters occurs in the cytoplasm.

The aim of this work is to produce ethyl oleate ester by enzymatic esterification of oleic acid with ethanol. A lipase from Candida antarctica type B was used at a temperature of 55 °C.

Background: Cystic Fibrosis (CF) is a genetic disease which affects the patient’s lungs, pancreas, liver, kidney and intestine and lacks sulfatase enzyme, leading to mucopolysaccharidosis. Colistin sulfate acts by interacting with phospholipids of bacterial cell membranes. Sulfatase enzyme reduces the high levels of sulfated glycosaminoglycans and glycolipids by the hydrolysis of sulfate esters in lysosome.

This addition reaction follows the Markovnikov rule. This reaction provides a new simple method for preparing carboxylic esters from alkenes. It was also found that this method is useful for formylation.

Abstract:

ABSTRACT We identified trace metabolites produced during the anaerobic biodegradation of H26- and D26-n-dodecane by an enrichment culture that mineralizes these compounds in a sulfate-dependent fashion. The metabolites are dodecylsuccinic acids that, in the case of the perdeuterated substrate, retain all of the deuterium atoms. The deuterium retention and the gas chromatography-mass spectrometry fragmentation patterns of the derivatized metabolites suggest that they are formed by C—H or C—D addition across the double bond of fumarate. As trimethylsilyl esters, two nearly coeluting metabolites

Abstract:

Inorganic sulfate concentrations in the cytoplasm of human bronchial epithelial cells exceeded levels in the bathing medium under all circumstances tested. Cell sulfate concentrations were directly related to medium sulfate concentrations and inversely related to medium chloride concentrations. In physiological media there was a sulfate compartment of approximately 0.3 mM that exchanged very slowly with extracellular sulfate. In media lacking chloride, sulfate was accumulated by the cells to a level as high as 2 mM. Sulfate uptake was markedly inhibited by external chloride and by stilbene sul

Abstract:

Cellulose nanocrystals (CNCs) are a biorenewable resource, which may be chemically modified to impart specific properties. Modified CNCs have found use in imaging applications, as rheology modifiers, polymer reinforcements, barrier and/or optical films, and nanocomposites. Nanoparticle dimensions of CNCs are typically 5–10 nm in width, with lengths of <100–300 nm. However, the physical properties are dependent upon the number and nature of the surface charge groups imparted during preparation. In the case of CNCs produced from sulfuric acid hydrolysis, the sulfated surface groups may be par
