xenobiotic degradation aromatic compound degradation dibenzofuran degradation KEGG:map01100 KEGG:map01120 KEGG:map00621 GO:0019340 PMID:8981980 pathway PMID:8226678 MetaCyc:P662-PWY UPa:UPA00808 Degradation of dibenzofuran. Dibenzofuran is created as by-products during industrial processes such as incineration, paper bleaching, and chemical synthesis. It has also been used as an insecticide, and is formed from the photolysis of chlorinated biphenyl ethers. Several species of bacteria capable degrading dibenzofuran have been identified, including Pseudomonas, Xanthomonas, Terrabacter, Microbacterium, and Rhodococcus.
