Sulfur is an essential element for life and the metabolism of organic sulfur compounds plays an important role in the global sulfur cycle. Sulfur occurs in various oxidation states ranging from +6 in sulfate to -2 in sulfide (H2S). Sulfate reduction can occur in both an energy consuming assimilatory pathway and an energy producing dissimilatory pathway. The assimilatory pathway, which is found in a wide range of organisms, produces reduced sulfur compounds for the biosynthesis of S-containing amino acids and does not lead to direct excretion of sulfide. In the dissimilatory pathway, which is restricted to obligatory anaerobic bacterial and archaeal lineages, sulfate (or sulfur) is the terminal electron acceptor of the respiratory chain producing large quantities of inorganic sulfide. Both pathways start from the activation of sulfate by reaction with ATP to form adenylyl sulfate (APS). In the assimilatory pathway [MD:M00176] APS is converted to 3-phosphoadenylyl sulfate (PAPS) and then reduced ...

Abstract: The prediction of the oxidation rate of elemental sulfur (S0) is a critical step in sulfur (S) fertilizer strategy to supply plant-available sulfur. An incubation experiment was conducted to determine the rate and amount of S0 oxidation in relation to the contribution of Thiobacillus spp. and aerobic heterotrophic S-oxidizing bacteria. After 84 days, 16.3% and 22.4% of the total S0 applied to the soil were oxidized at 20 and 30 °C, respectively. The oxidation of S0 proved to be a two-step process with a rapid oxidation during the first 28 days and a slow oxidation from then on. The highest oxidation rate of 12.8 μg S cm−2 d−1 was measured during the first two weeks at 30 °C. At 20 °C the highest oxidation rate of 10.2 μg S cm−2 d−1 was obtained from two to four weeks after start of the experiment. On an average the soil pH declined by 3.6 and 4.0 units after two weeks of experiment. At the same time the electric conductivity increased nine times. With the oxidation of S0 ...

Press Release issued Jan 7, 2016: Chloromethane, also known as methyl chloride, HCC-40 or R-40 belongs to a group of organic compounds called haloalkanes. It is an extremely flammable colorless gas which is usually detected at toxic levels. Chloromethane is synthesized by boiling a mixture of sodium chloride, sulfuric acid and methanol. Significant amount of chloromethane is produced naturally in the oceans by the action of sunlight on chlorine and biomass in sea foam. It is majorly used in manufacturing silicone polymers, butyl rubber and in petroleum refining. Chloromethane was initially used as a refrigerant, but was discontinued on account of its flammability and toxicity. Due to its substantial toxic effects, it is no longer used in consumer products. Different types of chloromethanes such as methyl chloride, methylene chloride, chloroform, and carbon tetrachloride are produced in the industry. Methyl chloride is the largest segment and is also the most important type of chloromethane, largely used

16S ribosomal RNAs (rRNA) of 12 methylotrophic bacteria have been almost completely sequenced to establish their phylogenetic relationships. Methylotrophs that are physiologically related are phylogenetically diverse and are scattered among the purple eubacteria (class Proteobacteria). Group I methylotrophs can be classified in the β-and the γ-subdivisions and group II methylotrophs in the α-subdivision of the purple eubacteria, respectively. Pink-pigmented facultative and non-pigmented obligate group II methylotrophs form two distinctly separate branches within the α-subdivision. The secondary structures of the 16S rRNA sequences of Methylocystis parvus strain OBBP, Methylosinus trichosporium strain OB3b, Methylosporovibrio methanica strain 81Z and Hyphomicrobium sp. strain DM2 are similar, and these non-pigmented obligate group II methylotrophs form one tight cluster in the α-subdivision.

Trimethylamine dehydrogenases from bacterium W3A1 and Hyphomicrobium X and the dimethylamine dehydrogenase from Hyphomicrobium X were found to contain only one kind of subunit. The millimolar absorption coefficient of a single [4Fe-4S] cluster in trimethylamine dehydrogenase from bacterium W3A1 was estimated to be 14.8 mM-1 . cm-1 at 443 nm. From this value a 1:1 stoicheiometry of the prosthetic groups, 6-S-cysteinyl-FMN and the [4Fe-4S] cluster, was established. Millimolar absorption coefficients of the three enzymes were in the range 49.4-58.7 mM-1 . cm-1 at approx. 440 nm. This range of values is consistent with the presence of two [4Fe-4S] clusters and two flavin residues, for which the millimolar absorption coefficient had earlier been found to be 12.3 mM-1 . cm-1 at 437 nm. The N-terminal amino acid was alanine in each of the three enzymes. Sequence analysis of the first 15 residues from the N-terminus of dimethylamine dehydrogenase indicated a single unique sequence.

This study demonstrated the feasibility of implementing of MBR in pharmaceutical wastewater independently, and concluded different applications of MBR in industries. Membrane bioreactor (MBR) technology was a new wastewater treatment technology with a combination of membrane separation technology and biological treatment technology, which had unique advantages on pharmaceutical wastewater treatment. The modified membrane rector design provided a significantly lower concentration of NH3-N, Phosphorous, Total Nitrogen and COD around the membranes, and subsequently a more sustainable membrane performance due to much lower overall fouling rates. In this paper, the classification and structure of biological waste water treatment by using MBR technology were summed up along with some examples of MBR in industrial wastewater treatment, which was emphatically analyzed and discussed. Finally, the prospect of MBR in industrial wastewater treatment was described. The industrial wastewater was a high-strength

Previous studies from this laboratory described the kinetic characteristics of the inhibition by tosylphenylalanine chloromethane (TosPheCH2Cl) on superoxide anion production by human neutrophils (PMN) stimulated with a phorbol ester (PMA). In this study we present further evidence concerning the potential role of the chloromethane target in the normal cellular activation of NADPH oxidase. When PMN are treated with TosPheCH2Cl and subsequently PMA, or with the two reagents in the reverse order, the inhibition of superoxide production by the intact cells is still present in a particulate NADPH oxidase fraction prepared from these cells. Nevertheless, when cells incubated only with the chloromethane and not with PMA are disrupted, both their cytosolic and membrane fractions are fully competent in the cell-free activation assay. Thus, the chloromethane target has a role in NADPH oxidase activation exclusively at the cellular level. This observation constitutes additional evidence in favour of the ...

Deputy Steve Luce has signed a Ministerial Decision that immediately revokes the sale and distribution in Jersey of all plant protection products containing the active ingredient Linuron.. Linuron is used to control weeds and grasses in a range of field crops, particularly the Jersey Royal potato crop. Linuron is highly soluble and persistent in water. It was detected in Jersey waters, including Val de la Mare reservoir, on a number of occasions last year.. The minister for the Environment, deputy Steve Luce said: The ban on pesticides containing Linuron adds to the package of measures already being delivered by the farming and related sectors. It will support the new Water Management Plan by helping to secure the clean water which our health, economic activity and biodiversity relies on. I have discussed the ban with the industry and everyone recognises the need to keep Linuron out of Jerseys water. The Department of the Environment and Jersey Water have been working with the farming ...

Currently, Cu-containing chalcopyrite-based solar cells provide the highest conversion efficiencies among all thin-film photovoltaic (PV) technologies. They have reached efficiency values above 20%, the same performance level as multi-crystalline silicon-wafer technology that dominates the commercial PV market. Chalcopyrite thin-film heterostructures consist of a layer stack with a variety of interfaces between different materials. It is the chalcopyrite/buffer region (forming the p-n junction), which is of crucial importance and therefore frequently investigated using surface and interface science tools, such as photoelectron spectroscopy and scanning probe microscopy. To ensure comparability and validity of the results, a general preparation guide for realistic surfaces of polycrystalline chalcopyrite thin films is highly desirable. We present results on wet-chemical cleaning procedures of polycrystalline Cu(In{sub 1-x}Ga{sub x})Se{sub 2} thin films with an average x = [Ga]/([In] + [Ga]) = ...

Summary: Dichloromethane (DCM) dehalogenases enable facultative methylotrophic bacteria to utilize DCM as sole carbon and energy source. DCM-degrading aerobic methylotrophic bacteria expressing a type A DCM dehalogenase were previously shown to share a conserved 4.2 kb BamHI DNA fragment containing the dehalogenase structural gene, dcmA, and dcmR, the gene encoding a putative regulatory protein. Sequence analysis of a 10 kb DNA fragment including this region led to the identification of three types of insertion sequences identified as IS 1354, IS1355 and IS1357, and also two ORFs, orf353 and orf192, of unknown function. Two identical copies of element IS 1354 flank the conserved 4.2 kb fragment as a direct repeat. The occurrence of these newly identified IS elements was shown to be limited to DCM-utilizing methylotrophs containing a type A DCM dehalogenase. The organization of the corresponding dcm regions in 12 DCM-utilizing strains was examined by hybridization analysis using IS-specific probes. Six
