Acetone stress response in Desulfovibrio vulgaris

ABSTRACT: Desulfovibrio vulgaris has been studied extensively for its potential in the bioremediation of heavy metals and radionuclides. Hydrocarbons and solvents, as frequent environmental co-contaminants, have been reported to inhibit microbial activities and thereby pose a limitation on bioremediation efficiency. As a part of the Genomes: GTL project to deduce the stress response pathways in metal/radionuclide reducing bacteria, we studied the responses of D. vulgaris to acetone, which is a ketone solvent frequently observed at contaminated DOE sites. Growth experiments in closed vessels at 37 °C indicated that D. vulgaris could maintain normal growth with 3%(v/v) acetone following a 1-h lag phase. When the acetone concentration was raised to 5%(v/v), we observed a 2-h lag phase followed by a gr
