1.14.12.22 degradation expression of genes CarAacd in dibenzothiophene degrader Rhodococcus erythropolis results in a strain capable of efficiently degrading dibenzothiophene and carbazole simultaneously. About 37% of the carbazole present, 0.8% by weight, is removed after treatment for 24 h.The recombinant strain can also degrade various alkylated derivatives of carbazole and dibenzothiophene in FS4800 crude oil by just a one-step bioprocess -, 707220
