Query: NC_014387:79808 Butyrivibrio proteoclasticus B316 chromosome 1, complete genome
Lineage: Butyrivibrio proteoclasticus; Butyrivibrio; Lachnospiraceae; Clostridiales; Firmicutes; Bacteria
General Information: Butyrivibrio proteoclasticus, formerly Clostridium proteoclasticum, was isolated from rumen contents of a cow. This organism is highly proteolytic and therefore probably involved in the degradation of proteins in the rumen.
Subject: NC_011883:2826000 Desulfovibrio desulfuricans subsp. desulfuricans str. ATCC 27774,
Lineage: Desulfovibrio desulfuricans; Desulfovibrio; Desulfovibrionaceae; Desulfovibrionales; Proteobacteria; Bacteria
General Information: Desulfovibrio desulfuricans subsp. desulfuricans str. ATCC 27774 was isolated from the rumen of a sheep. D. desulfuricans reduces sulfate to sulfide found in soil, freshwater, saltwater and the intestinal tract of animals. This organism grows anaerobically and utilizes a wide variety of electron acceptors, including sulfate, sulfur, nitrate, and nitrite, as well as others. The nitrate reduction pathway is not expressed while sulfate is available. Alternatively, the sulfate reduction pathway is constitutively expressed when the cells are growing with nitrate reduction. A number of toxic metals are reduced, including uranium (VI), chromium (VI) and iron (III), making this organism of interest as bioremediator. Metal corrosion, a problem that is partly the result of the collective activity of this bacterium, results in billions of dollars in losses each year to the petroleum industry. This organism is responsible for the production of poisonous hydrogen sulfide gas in marine sediments and in terrestrial environments such as drilling sites for petroleum products.
