The potential application of carbazole-degrading bacteria for dioxin bioremediation.

Extensive research has been conducted over the years on the bacterial degradation of dioxins and their related compounds including carbazole, because these chemicals are highly toxic and has been widely distributed in the environment. There is a pressing need to explore and develop more bacterial strains with unique catabolic features to effectively remediate dioxin-polluted sites. Carbazole has a chemical structure similar to dioxins, and the degradation pathways of these two chemicals are highly homologous.

sp. nov., isolated from the rhizosphere soil of .

A novel bacterial strain, N4, was isolated from the soil of a groundnut field in Nghean province, Vietnam. The phylogenetic, chemotaxonomic and phenotypic characteristics of this strain were determined. Cells of strain N4 were Gram-negative, aerobic, endospore-forming and rod-shaped.
