Notes:
Burkholderia sp. AA1 isolated from a diesel fuel-contaminated site degraded toluene, as well as a wide range of alkanes from decane (C8) to pentacosane (C25) as sole carbon and energy sources. This strain also utilized m-toluate, p-toluate, o-toluate, and m-cresol as sole carbon and energy sources. Toluene- and toluate-grown cells showed catechol 2,3-dioxygenase activity and indole oxidation activity that is exhibited by some toluene oxygenation enzymes. The catechol 2,3-dioxygenase gene (catB) was cloned and sequenced. Its deduced amino acid sequence is analogous to the extradiol dioxygenases cloned from a variety of microorganisms. A DNA fragment containing the genes for the indole oxidation activity was cloned and sequenced. A seven-gene cluster designated as tbhABCDEFG was identified. Significant similarities were found with multicomponent monooxygenase systems for toluene, benzene and phenol from different bacterial strains.
