Metabolic Flexibility of Sulfate-Reducing Bacteria
Dissimilatory sulfate-reducing prokaryotes (SRB) are a very diverse group of anaerobic bacteria that are omnipresent in nature and play an imperative role in the global cycling of carbon and sulfur. In anoxic marine sediments sulfate reduction accounts for up to 50% of the entire organic mineralization in coastal and shelf ecosystems where sulfate diffuses several meters deep into the sediment....
متن کاملSulfurous Analysis of Bioelectricity Generation from Sulfate-reducing Bacteria (SRB) in a Microbial Fuel Cell
The current importance of energy emphasizes the use of renewable resources (such as wastewater) for electricity generation by microbial fuel cell (MFC). In the present study, the native sulfate-reducing bacterial strain (R.gh 3) was employed simultaneously for sulfurous component removal and bioelectricity generation. In order to enhance the electrical conductivity and provision of a compatible...
متن کاملEtiological Role of Sulfate-Reducing Bacteria in the Development of Inflammatory Bowel Diseases and Ulcerative Colitis
Inflammatory bowel disease and ulcerative colitis are complex multifactorial diseases of unknown etiology. The etiological role of the sulfate-reducing bacteria Desulfovibrio piger Vib-7 and Desulfomicrobium sp. Rod-9 in the development of these inflammatory diseases in rats was studied. Applying sulfate-reducing bacteria, ulcerative colitis in the animals was experimentally induced at the fist...
متن کاملActivity and kinetic properties of phosphotransacetylase from intestinal sulfate-reducing bacteria.
Phosphotransacetylase activity and the kinetic properties of the enzyme from intestinal sulfate-reducing bacteria Desulfovibrio piger and Desulfomicrobium sp. has never been well-characterized and has not been studied yet. In this paper, the specific activity of phosphotransacetylase and the kinetic properties of the enzyme in cell-free extracts of both D. piger Vib-7 and Desulfomicrobium sp. R...
متن کاملSulfate-reducing bacteria in temporarily oxic sediments with bivalves
Under seasonally fluctuating redox conditions in sediment of Kiel Bay (eastern Baltic Sea), viable counts (MPN) of sulfate-reducing bacteria (SRB) ranged between 4 X 102 and 7 X 104 cm-3 These MPN appeared fairly independent of ambient redox potentials and followed peaks of phytoplankton productivity in the water column with a time lag of 2 to 3 wk. The relative proportions of SRB using acetate...
