Plants and algae were found useful in the decontamination of water polluted with chlorinated phenolic compounds. An artificial wastewater contaminated with up to 350 ppm herbicide 2,4-dichlorophenol (2,4-DCP), was successfully treated using horseradish, potato and Ulva sp. (sea lettuce), amended with H2O2. Horseradish -mediated provided up to 99% removal of 2,4-DCP from model solution, while, p...

Granular activated carbon (GAC), in the presence of dilute aqueous hypochlorite solutions typical of those used in water treatment, was converted to a reagent capable of carrying out free-radical coupling reactions and other oxidations of dilute aqueous solutions of phenols. The products included biphenyls with chlorine and hydroxyl substitution (hydroxylated polychlorinated biphenyls). For exa...

2. o-Dichlorobenzene also gives rise to 3:4dichlorophenylmercapturic acid as a minor metabolite (5% of the dose). 3. p-Dichlorobenzene (0.5 g./kg.) is mainly oxidized to 2:5-dichlorophenol which is excreted conjugated. 2:5-Dichloroquinol is also formed (about 6% of the dose) but in contrast with o-dichlorobenzene no mercapturic acid or dichlorocatechol is formed. 4. The excretion ofthe metaboli...

A multicomponent protein complex containing manganese (II)-dependent peroxidase, laccase and beta-glucosidase was isolated from culture extracts of the white rot basidiomycete Lentinula edodes. This protein complex showed a single protein band on native polyacrylamide gel electrophoresis (PAGE). On sodium dodecyl sulfate (SDS)-PAGE, however, it displayed three major bands and several additional...
