ABSTRACT Role of microbes in bioremediation of oil spills has become inevitable owing to their eco friendly nature. This study focused on the isolation and characterization of bacterial strains with superior oil degrading potential from crude-oil contaminated soil. Three such bacterial strains were selec...

Over-expression of Mycobacterium neoaurum 3-ketosteroid-∆ 1-dehydrogenase in Corynebacterium crenatum for efficient bioconversion of 4-androstene-3, 17-dione to androst-1, 4-diene-3, 17-dione

Background: 3-Ketosteroid-∆¹-dehydrogenase (KSDD), a flavoprotein enzyme, catalyzes the bioconversion of 4-androstene-3,17-dione (AD) to androst-1,4-diene-3,17-dione (ADD). To date, there has been no report about characterization of KSDD from Mycobacterium neoaurum strains, which were usually empl...
