(Submitter supplied) The syntrophic growth of strain 195 with Desulfovibrio vulgaris Hildenborough (DVH) and/or Methanobacterium congolense (MC) enhanced TCE dechlorination process by faster dechlorination rate and more robust growth. Transcriptomes of strain 195 grown in isolation, co- and tri-cultures were obtained by microarray experiments to find out the differential expressed genes corresponding to the syntrophic growth. more...

(Submitter supplied) Dehalococcoides bacteria can reductively dehalogenate a wide range of halogenated organic pollutants. In this study, DNA microarrays were applied to monitor dynamic changes in the transcriptome as Dehalococcoides ethenogenes strain 195 transitioned from exponential growth into the stationary phase. In total, 415 non-redundant genes were identified as differentially expressed. As expected, genes involved with translation and energy metabolism were down-regulated while genes involved with general stress response, transcription, and signal transduction were up-regulated. more...

(Submitter supplied) The gene expression profile of wild-type Desulfovibrio vulgaris grown on cathodic hydrogen, generated at an iron electrode surface with an imposed negative potential of -1.1 V (cathodic protection conditions). The gene expression profile of cells grown on cathodic hydrogen was compared to that of cells grown with gaseous hydrogen bubbling through the culture. Relative to the latter, the electrode-grown cells over-expressed two hydrogenases, the hyn1 genes for [NiFe] hydrogenase-1, and the hyd genes, encoding [Fe] hydrogenase. more...

(Submitter supplied) 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. more...

(Submitter supplied) The effect of sulfide stress on Desulfovibrio vulgaris Hildenborough (DvH) gene expression was determined by comparing the gene expression profiles of DvH under conditions in which sulfide was allowed to accumulate (high sulfide, average concentration 10 mM) against DvH cells grown under conditions in which sulfide was removed by continuous gassing (low sulfide, average concentration 1 mM). High sulfide significantly decreased the instantaneous growth rate constant and final cell density of the culture indicating a decreased bioenergetic fitness. more...
