| Abstract: | Summary The ability of the nocardioform actinomycete Rhodococcus rhodochrous to metabolize selected lignin model compounds was studied. The compounds studied included cinnamic and ferulic acids and dimers possessing intermonomeric linkages that are characteristic of the lignin molecule. R. rhodochrous reduced the carbonyl group of anisoin, a 1,2-diarylethane ( -1) structure to (1R,2R)-1,2-bis(4-methoxyphenyl)ethane-1,2-diol with an enantiomeric excess of .98%. Cleavage of 1,2-diarylethane and -O-4 structures by this strain could not be detected under our metabolic conditions.
