Project description:The sulfate-reducing bacterium Desulfovibrio vulgaris Hildenborough possesses four periplasmic hydrogenases to facilitate the oxidation of molecular hydrogen. These include an [Fe], a [NiFeSe] and two [NiFe] hydrogenases encoded by the hyd, hys, hyn1 and hyn2 genes, respectively. In order to understand their cellular functions the expression levels of these hydrogenases, along with the growth rate analysis of mutant strains, was determined during growth on defined media under 3 different conditions. These conditions incuded lactate or hydrogen at either 5% or 50% (vol/vol) used as the sole electron donor for sulfate reduction. Keywords: Electron donor change
