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

Keywords: Electron donor change For each condition 2 unique biological samples were hybridized to 4 arrays that each contained duplicate spots. Genomic DNA was used as universal reference. After total intensity normalization the SAM (significance analysis of microarrays) was used to find differentially expressed genes.

Project description:In this study, the effect of nitroprusside on protein expression of the model sulfate reducing bacterial isolate (Desulfovibrio vulgaris Hildenborough) was investigated. Three different experiments were done with different exposure time to nitroprusside (30 min, 1 hour, and 3 hours). In each experiment, the culture was grown in quadruplet of serum bottles containing 40 ml complex medium (Postgate medium B) under anaerobic condition at 30oC. At mid-log growth phase, each of the quadruplet culture was divided into two (20 ml each) and nitroprusside (0.25 mM) was added to one of each bottle while the other bottles were used as controls. After 30 min, 1 hour, and 3 hours of exposure to nitroprusside, the culture (1 ml) was pelleted and used for proteomic analysis.
