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 ...
