Appl Environ Microbiol. Janssen DB, Scheper A, Dijkhuizen L, Witholt B. 1979 May 31; 320:214–230. Appl. Suspensions of Nitrosomonas europaea catalyzed the ammonia-stimulated aerobic transformation of the halogenated aliphatic compounds dichloromethane, dibromomethane, trichloromethane (chloroform), bromoethane, 1,2-dibromoethane (ethylene dibromide), 1,1,2-trichloroethane, 1,1,1-trichloroethane, monochloroethylene (vinyl chloride), gem-dichloroethylene, cis- and trans … The transformation of nine halogenated aliphatic compounds by 10 g/L (0.5 m2/L) FeS at pH 8.3 was studied in batch experiments. Aromatic compounds are subject to electrophilic halogenation: RC 6 H 5 + X 2 → HX + RC 6 H 4 X. The halogenated aliphatic hydrocarbon is a derivative in which the hydrogen atom in the … A bacterium that is able to utilize a number of halogenated short-chain hydrocarbons and halogenated carboxylic acids as sole carbon source for growth was identified as a … Microbial degradation of volatile halogenated aliphatic compounds: Use of specialized cultures for waste gas treatment.

An aliphatic compound is an organic compound containing carbon and hydrogen joined together in straight chains, branched chains, or non-aromatic rings. Structure. The role of the Lewis acid is to polarize the halogen-halogen bond, making the halogen molecule more electrophilic. A nickel catalyst that promotes carboxylation of halogenated hydrocarbons at remote aliphatic sites with carbon dioxide via tunable and controllable chain-walking is described. Depression of the central nervous system (CNS) is the most outstanding acute effect of many of the halogenated aliphatic hydrocarbons.

DOI: 10.1021/es980946x. One of the major structural groups of organic molecules, the aliphatic compounds include the alkanes, alkenes, and alkynes and [Google Scholar] Marc … Halogenated acetylene compounds are unstable and should be treated as explosives. Degradation of halogenated aliphatic compounds by Xanthobacter autotrophicus GJ10. [PMC free article] Bouwer EJ, McCarty PL. Halogenated aliphatic compounds are moderately or very reactive. Ann N Y Acad Sci. Kinetics of the Transformation of Halogenated Aliphatic Compounds by Iron Sulfide. This reaction works only for chlorine and bromine and is carried in the presence of a Lewis acid such as FeX 3 (laboratory method). The least complex aliphatic compound is methane (CH 4). D B Janssen, ... Abstract. ... saturated or unsaturated, aliphatic or aromatic. A bacterium that is able to utilize a number of halogenated short-chain hydrocarbons and halogenated carboxylic acids as sole carbon source for growth was identified as a strain of Xanthobacter autotrophicus. A method of degrading halogenated aliphatic hydrocarbons is disclosed comprising incubating microorganisms capable of degrading halogenated aliphatic hydrocarbons by an aromatic degradative pathway together with the halogenated aliphatic hydrocarbons under conditions such that said aromatic degradative pathway is active.
