Effect of sulfide on growth physiology and gene expression of Desulfovibrio vulgaris Hildenborough

ABSTRACT: 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. Changes in gene expression caused by exposure to high sulfide were determined using full-genome DvH microarrays. The transcription of ribosomal protein-encoding genes was decreased, in agreement with the lower growth rate of DvH under high sulfid
