(iii) Microbial transformation of biarylethers, cyclic biarylethers, bialylketones, halogenated bibenzodioxins and dibenzofurans are used to avoid the problem of release of effluents with pollutants.
For instance, Pseudomonas strains have been isolated, which selectively deoxygcnate the 1,2 positions of substituted biaryethers and biarylketones (e.g. biphenylether, xanthcne, dibeozofuran, dibenzo-p dioxin).
(iv) Microbial degradation of chloro-, dichloro- and trichloromethanes and carbontftra chloride is also used to dea1 with the problem.
