Molecular biological enhancement of coal biodesulfurization [PDF]
, 1989 The overall objectives of this project is to use Molecular Genetics to develop strains of bacteria (esp. Rhodococcus) with enhanced ability to remove sulfur from coal, and to obtain data that will allow the performance and economics of a coal biodesulfurization process to be predicted. 5 figs.

Isolation and identification of a TetR family protein that regulates the biodesulfurization operon
AMB Express, 2019 Biodesulfurization helps in removal of sulfur from organosulfur present in petroleum fractions. All microorganisms isolated to date harbor a desulfurization operon consisting of three genes dszA, -B and -C which encode for monooxygenases (DszA & C) and ...

Isolation and Identification of Dibenzothiophene Biodesulfurizing Bacteria [PDF]
American Journal of Bioscience and Bioengineering, 2015 This study aimed to obtain efficient bacteria capable of desulfurizing dibenzothiophene (DBT). For this purpose forty oil contaminated soil samples were collected from different sites in Iraq. It was found that three isolates (M9, M19 and S25) had the ability to desulfurize DBT (cleave C-S bond) and converted it to 2-hydroxybiphenel (2-HBP) or other ...
