ENZYMATIC DEHALOGENATION OF CERTAIN BROMINATED AND CHLORINATED COMPOUNDS

Enzymatic dehalogenation of certain brominated and chlorinated compounds.

The dehalogenation in vivo of brominated aliphatic hydrocarbons such as methyl bromide (1) and bromochloromethane (2) has been demonstrated by recovery of inorganic bromide from blood and urine. The intracellular formation of bromide and methyl alcohol from methyl bromide has been advanced as an explanation for its prolonged toxic effect (3). Evidence for the splitting of chlorinated aliphatic ...

Reductive dehalogenation of brominated phenolic compounds by microorganisms associated with the marine sponge Aplysina aerophoba.

Marine sponges are natural sources of brominated organic compounds, including bromoindoles, bromophenols, and bromopyrroles, that may comprise up to 12% of the sponge dry weight. Aplysina aerophoba sponges harbor large numbers of bacteria that can amount to 40% of the biomass of the animal. We postulated that there might be mechanisms for microbially mediated degradation of these halogenated ch...
