| thermodesulforhabdus norvegicus gen. nov., sp. nov., a novel thermophilic sulfate-reducing bacterium from oil field water. | a novel gram-negative, thermophilic, acetate-oxidizing, sulfate-reducing bacterium, strain a8444, isolated from hot north sea oil field water, is described. the rod-shaped cells averaged 1 micron in width and 2.5 microns in length. they were motile by means of a single polar flagellum. growth was observed between 44 and 74 degrees c, with an optimum at 60 degrees c. spores were not produced. sulfate and sulfite were used as electron acceptors. sulfur, thiosulfate, nitrate, fumarate, and pyruvate ... | 1995 | 8572886 |
| desulfobacca acetoxidans gen. nov., sp. nov., a novel acetate-degrading sulfate reducer isolated from sulfidogenic granular sludge. | a mesophilic sulfate reducer, strain asrb2t, was isolated with acetate as sole carbon and energy source from granular sludge of a laboratory-scale upflow anaerobic sludge bed reactor fed with acetate and sulfate. the bacterium was oval-shaped, 1.3 x 1.9-2.2 microns, non-motile and gram-negative. optimum growth with acetate occurred around 37 degrees c in freshwater medium (doubling time: 1.7-2.2 d). enzyme studies indicated that acetate was oxidized via the carbon monoxide dehydrogenase pathway. ... | 1999 | 10319454 |
| desulfacinum hydrothermale sp. nov., a thermophilic, sulfate-reducing bacterium from geothermally heated sediments near milos island (greece). | a thermophilic, sulfate-reducing bacterium, strain mt-96t, was isolated from an active, marine, shallow-water hydrothermal vent system. it used a large variety of substrates, ranging from simple organic compounds to long-chain fatty acids, as electron donors. autotrophic growth was possible with h2 and co2 in the presence of sulfate. sulfate, thiosulfate and sulfite were used as electron acceptors. sulfur and nitrate were not reduced. fermentative growth was obtained with pyruvate, but not with ... | 2000 | 10843068 |
| [desulfacinum subterraneum sp.nov.--a new thermophilic sulfate-reducing bacterium isolated from a high temperature oil field ]. | a new thermophilic sulfate-reducing bacterium isolated from the high-temperature white tiger oil field (vietnam) is described. cells of the bacterium are oval (0.4-0.6 by 0.6-1.8 microns), nonmotile, non-spore-forming, and gram-negative. growth occurs at 45 to 65 degrees c (with an optimum at 60 degrees c) at nacl concentrations of 0 to 50 g/l. in the course of sulfate reduction, the organism can utilize lactate, pyruvate, malate, fumarate, ethanol, salts of fatty acids (formate, acetate, propio ... | 2001 | 11558281 |
| prokaryotic community structure and sulfate reducer activity in water from high-temperature oil reservoirs with and without nitrate treatment. | sulfate-reducing prokaryotes (srp) cause severe problems like microbial corrosion and reservoir souring in seawater-injected oil production systems. one strategy to control srp activity is the addition of nitrate to the injection water. production waters from two adjacent, hot (80 degrees c) oil reservoirs, one with and one without nitrate treatment, were compared for prokaryotic community structure and activity of srp. bacterial and archaeal 16s rrna gene analyses revealed higher prokaryotic ab ... | 2009 | 19801479 |
| desulfosoma caldarium gen. nov., sp. nov., a thermophilic sulfate-reducing bacterium from a terrestrial hot spring. | a thermophilic, sulfate-reducing bacterium, designated strain usba-053(t), was isolated from a terrestrial hot spring located at a height of 2500 m in the colombian andes (5° 45' 33.29″ n 73° 6' 49.89″ w), colombia. cells of strain usba-053(t) were oval- to rod-shaped, gram-negative and motile by means of a single polar flagellum. the strain grew autotrophically with h(2) as the electron donor and heterotrophically on formate, propionate, butyrate, valerate, isovalerate, lactate, pyruvate, ethan ... | 2011 | 20418410 |
