Yoshida, N. published the artcileReductive dechlorination of PCBs and other chlorinated compounds by novel anaerobic bacterial species, Formula: C8H5ClO2, the main research area is anaerobic bacteria polychlorinated biphenyl chlorinated compound reductive dechlorination.

Bacteria that can reductively dechlorinate chlorinated compounds such as polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins (PCDDs) have been receiving much attention in the field of environmental science and technol. In this study, the enrichment of bacteria that dechlorinate PCBs and PCDDs was performed by the sequentially transferred culture amended with 4,5,6,7-tetrachlorophthalide (fthalide) and single fatty acids from an uncontaminated paddy field. The enrichment cultures amended with lactate (KFL) or formate (KFF) maintained the activity to dechlorinate fthalide to 4-chlorophthalide in the sequential transfer but not the culture amended with acetate and butyrate. The only KFL-culture dechlorinated diverse chlorinated compounds including 2,3,4,5-tetrachlorobiphenyl, 2,3,4-trichlorobiphenyl, 1,2,3-trichlorodibenzo-p-dioxin. A further enrichment of KLF-culture provided an enrichment culture, KFC4A-culture, containing uniformly small short rods. Microbial community anal. based on 16S rRNA genes revealed the involvement of two phylogenetically distinct operational taxonomic units (OTUs) of Dehalobacter sp. (FTH1 and FTH2) with the dechlorination of chlorinated compounds Dehalobacter restrictus TEA was their closest relative, and had 97.5% and 97.3% of 16SrRNA gene similarities for FTH1 and FTH2, resp. These results demonstrate the capacity of uncontaminated paddy soil to dechlorinate PCBs and PCDDs, and the involvement of Dehalobacter sp.

Yoshida, Naoko published the artcileA novel Dehalobacter species is involved in extensive 4,5,6,7-tetrachlorophthalide dechlorination, Category: benzofurans, the main research area is novel Dehalobacter tetrachlorophthalide dechlorination waste fungicide rice blast Dehalobacter.

The purpose of this study was the enrichment and phylogenetic identification of bacteria that dechlorinate 4,5,6,7-tetrachlorophthalide (com. designated “”fthalide””), an effective fungicide for rice blast disease. Sequential transfer culture of a paddy soil with lactate and fthalide produced a soil-free enrichment culture (designated the “”KFL culture””) that dechlorinated fthalide by using hydrogen, which is produced from lactate. Phylogenetic anal. based on 16S rRNA genes revealed the dominance of two novel phylotypes of the genus Dehalobacter (FTH1 and FTH2) in the KFL culture. FTH1 and FTH2 disappeared during culture transfer in medium without fthalide and increased in abundance with the dechlorination of fthalide, indicating their growth dependence on the dechlorination of fthalide. Dehalobacter restrictus TEA is their closest relative, with 97.5% and 97.3% 16S rRNA gene similarities to FTH1 and FTH2, resp.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. SDS of cas: 52010-22-7. Introducing a new discovery about 52010-22-7, Name is 4-Chlorophthalide

Biodegradable plastics (BPs) were evaluated for their applicability as sustainable and solid H2 donors for microbial reductive dechlorination of 4,5,6,7-tetrachlorophthalide (fthalide). After a screening test of several BPs, the starch-based plastic (SP) that produced the highest levels of H2 was selected for its use as the sole H2 donor in this reaction. Fthalide dechlorination was successfully accomplished by combining an H2-producing SP culture and a KFL culture containing Dehalobacter species, supplemented with 0.13% and 0.5% SP, respectively. The efficiency of H2 use in dechlorination was evaluated in a combined culture containing the KFL culture and strain Clostridium sp. Ma13, a new isolate that produces H2 from SP. Results obtained with this culture indicated increased H2-fraction for fthalide dechlorination much more in this culture than in compared with a KFL culture supplemented with 20mM lactate, which are 0.75 H2·glucose-1 and 0.015 H2·lactate-1 in mol ratio, respectively.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 52010-22-7, you can also check out more blogs about52010-22-7

An efficient method for preparation of substituted 1,2-phenylenedimethanols and aliphatic 1,4-diols that are valuable intermediates in organic synthesis, has been developed by the base-promoted reduction of isobenzofuran-1(3H)-ones and gamma-lactones with silane under mild conditions. Compared with traditional procedures using stoichiometric amounts of metal hydrides and alkyl reductants, the present method avoids the use of sensitive reagents and is operationally simple and a broad variety of functional groups are tolerated.
