Cometabolic degradation of dibenzofuran by biphenyl-cultivated Ralstonia sp. strain SBUG 290

Article Abstract:

Results show that in the presence of biphenyl, the dibenzofuran is cometabolized in Ralstonia sp. SBUG 290 to give rise to hydroxylated dibenzofuran compound. Data indicate that the compound is degraded via salicyclic acid using a lateral dioxygenation pathway.

Biotransformation of biphenyl by Paecilomyces lilacinus and characterization of ring cleavage products

Article Abstract:

The fungus Paecilomyces lilacinus can degrade the fungicide biphenyl. The result is five di- and trihydroxylated metabolites. The fungus also cleaved the rings, forming six-ring fission products.

Isolation and characterization of a dibenzofuran-degrading yeast: identification of oxidation and ring cleavage products

Article Abstract:

A strain of the yeast Trichosporon mucoides is capable of degrading dibenzofuran, a dioxin-like compound. High-performance liquid chromatography identified six primary metabolites. Four of these metabolites are monohydroxylated dibenzofurans, one is a dihydroxybenzofuran and the last is a glycolic acid derivative. Dihydroxybenzofuran and the glycolic acid derivative were the products of the oxidation of dibenzofuran hydroxylated at either the 2- or the 3-position.
