Fatal case of dichloromethane poisoning.
A 47-year-old man was found dead in a factory where dichloromethane (DCM) tanks were stocked. He was making an inventory of the annual stock of DCM contained in several tanks (5- to 8000-L capacity) by transferring the solvent into an additional tank with the help of compressed air. During this operation, one of the tanks overflowed and the man, who was not wearing any protection, was intoxicat...
متن کاملGrowth inhibition of Escherichia coli by dichloromethane in cells expressing dichloromethane dehalogenase/glutathione S-transferase.
Dichloromethane (DCM) dehalogenase converts DCM to formaldehyde via the formation of glutathione metabolites and generates 2 mol HCl per mol DCM metabolized. Growth of Escherichia coli expressing DCM dehalogenase was immediately and severely inhibited during conversion of 0.3 mM DCM. Intracellular pH (pH(i)) rapidly decreased and chloride ions were steadily released into the medium. Bacterial g...
متن کاملDichloromethane Injection: Case Report
Background: Dichloromethane (a chlorinated hydrocarbon) is normally used as a solvent. Dichloromethane poisoning has been reported from occupational exposure and the common routes of dichloromethane poisoning are ingestion and inhalation. Case presentation: We described a case of 51-year-old man who received subcutaneous injection of dichloromethane and presented with local wound necrosis at hi...
متن کاملEffects of bacterial host and dichloromethane dehalogenase on the competitiveness of methylotrophic bacteria growing with dichloromethane.
Methylobacterium sp. strain DM4 and Methylophilus sp. strain DM11 can grow with dichloromethane (DCM) as the sole source of carbon and energy by virtue of homologous glutathione-dependent DCM dehalogenases with markedly different kinetic properties (the kcat values of the enzymes of these strains are 0.6 and 3.3 S-1, respectively, and the Km values are 9 and 59 microM, respectively). These stra...
متن کاملDichloromethane dehalogenase with improved catalytic activity isolated from a fast-growing dichloromethane-utilizing bacterium.
A methylotrophic bacterium, denoted strain DM11, was isolated from groundwater and shown to utilize dichloromethane or dibromomethane as the sole carbon and energy source. The new isolate grew at the high rate of 0.22 h-1 compared with 11 previously characterized dichloromethane-utilizing bacteria (micromax, 0.08 h-1). The dichloromethane dehalogenase from strain DM11 (group B enzyme) was purif...
