Sphingomonas paucimobilis

The a-isomer of hexachlorocyclohexane exists in two enantiomeric forms, and both are degraded by Sphingomonas paucimobilis strain B90A by dehydrochlorination to 1,3,4, 6-tetrachlorocyclohexa-l,4-diene that is spontaneously degraded to 1,2,4-trichlorophenol. 

The degradation of 4-chlorobiphenyl by Sphingomonas paucimobilis strain BPSl-3 formed the intermediates 4-chlorobenzoate and 4-chlorocatechol. Fission products from the catechol reacted with NH4+ to produce chloropyridine carboxylates (Davison et al. 1996) (Figure 2.2c).

The degradation of 2,2 -dihydroxy- 3,3 -dimethoxybiphenyl-5,5 -dicarboxylate (5,5 -dehydro-divanillate) by Sphingomonas paucimobilis SYK-6 proceeds by partial de-O-methylation followed by extradiol hssion of the catechol to 2-hydroxy-3-methoxy-5-carboxybenzoate. Diversion of this into central metabolic pathways involves decarboxylation to vanillate by two separate decarboxylases LigWl and LigW2 (Peng et al. 2005).
