Degradation of polycyclic aromatic hydrocarbons by a newly isolated dibenzofuran-utilizing Janibacter sp. strain YY-1

The dibenzofuran (DF)-utilizing bacterium strain YY-1 was newly isolated from soil. The isolate was identified as Janibacter sp. with respect to its 16S rDNA sequence and fatty acid profiles, as well as various physiological characteristics. In addition to DF, strain YY-1 could grow on fluorene and...

Description
Summary:The dibenzofuran (DF)-utilizing bacterium strain YY-1 was newly isolated from soil. The isolate was identified as Janibacter sp. with respect to its 16S rDNA sequence and fatty acid profiles, as well as various physiological characteristics. In addition to DF, strain YY-1 could grow on fluorene and dibenzothiophene as sole sources of carbon and energy. It was also able to cometabolize a variety of polycyclic aromatic hydrocarbons including dibenzo-p-dioxin, phenanthrene, and anthracene. The major metabolites formed from DF, biphenyl, dibenzothiophene, and naphthalene were identified by using gas chromatography-mass spectrometry as 2,3,2'-trihydroxybiphenyl, biphenyl-dihydrodiol, dibenzothiophene 5-oxide, and coumarin, respectively. These results indicate that strain YY-1 can catalyze angular dioxygenation, lateral dioxygenation, and sulfoxidation.
