PROBLEM TO BE SOLVED: To provide a method for decomposing dibenzothiophenes, capable of reducing sulfur content in a hydrocarbon fuel, by using microorganisms which decompose the dibenzothiophenes. SOLUTION: This method for decomposing the dibenzothiophenes comprises using the microorganisms which decompose the benzothiophenes, wherein a vector coexpressing a gene which codes a dibenzothiophene-decomposing enzyme and another gene which codes an oxidation-reduction enzyme is introduced into the microorganisms. The gene which codes the dibenzothiophene- decomposing enzyme is derived from microorganisms belonging to Rhodococcus, Sphingomonas, Penibacillus, Agrobacterium, Mycobacterium, Gordona, Bacillus or Arthrobacter genus, or its mutant. The gene which codes the oxidation- reduction enzyme is derived from Paenibacillus polymyxa A-1 strain. |
