A convenient spectrophotometric assay (Gibbs’ assay) was used to determine the quantity of desulfurized product(Hydroxybiphenyl). This isolate did not grow on DBT, dibenzothiophene sulfone (DBTO2), or 2-Hydroxybiphenyl (HBP) as sole carbon sources. Biodesulfurization activity was observed only in growingcultures and depressed by free sulfate. The desulfurization trait was expressed at increasing levels during the exponential phase of growth and then declined in stationary-phase cells. This gram-positive, non-spore-forming, partially acid fast, polymorphic bacterium with the ability to desulfurize DBT or DBTO2 was identified as Rhodococcus sp. and designated strain FMF.}, keywords = {isolation,Biodesulfurization,Dibenzothiophene,Rhodococcus sp}, url = {https://www.ijbiotech.com/article_6893.html}, eprint = {https://www.ijbiotech.com/article_6893_22c99ee528362347341421a5f2e18688.pdf} }
