Biodegradation of carbazole and related compounds
- Univ. of Tokyo (Japan). Biotechnology Research Center
To cope with the acid rain caused by the release of sulfur dioxide from organic sulfur of fossil fuels during combustion, it is very important to obtain bacteria that are capable of efficiently removing the sulfur from organic sulfur compounds. Pseudomonas sp. CA10, which can grow on carbazole (CAR) as the sole source of carbon and nitrogen; Staphylococcus auricularis DBF63, which can grow on dibenzofuran (DBF) or fluorene (FN) as the sole source of carbon and energy; and Rhodococcus sp. Sy1, which can grow on dibenzo-thiophene (DBT) as a sole source of sulfur, were isolated. DBF-grown cells of S. auricularis DBF63 formed oxidation products of dibenzo-p-dioxin (DD). The possibility of degradation of tetrachlorodibenzo-p-dioxin is discussed. Based on the detection of the metabolic intermediates of CAR, DBF, FN and DD, the degradation pathways of these compounds are proposed.
