| thermodesulfatator indicus gen. nov., sp. nov., a novel thermophilic chemolithoautotrophic sulfate-reducing bacterium isolated from the central indian ridge. | a thermophilic, marine, anaerobic, chemolithoautotrophic, sulfate-reducing bacterium, strain cir29812t, was isolated from a deep-sea hydrothermal vent site at the kairei vent field on the central indian ridge. cells were gram-negative motile rods that did not form spores. the temperature range for growth was 55-80 degrees c, with an optimum at 70 degrees c. the nacl concentration range for growth was 10-35 g l(-1), with an optimum at 25 g l(-1). the ph range for growth was 6-6.7, with an optimum ... | 2004 | 14742485 |
| polyamine analysis for chemotaxonomy of thermophilic eubacteria: polyamine distribution profiles within the orders aquificales, thermotogales, thermodesulfobacteriales, thermales, thermoanaerobacteriales, clostridiales and bacillales. | cellular polyamines of 45 thermophilic and 8 related mesophilic eubacteria were investigated by hplc and gc analyses for the thermophilic and chemotaxonomic significance of polyamine distribution profiles. spermidine and a quaternary branched penta-amine, n4-bis(aminopropyl)norspermidine, were the major polyamine in thermocrinis, hydrogenobacter, hydrogenobaculum, aquifex, persephonella, sulfurihydrogenibium, hydrogenothermus, balnearium and thermovibrio, located in the order aquificales. thermo ... | 2004 | 15747232 |

| continuous enrichment cultures: insights into prokaryotic diversity and metabolic interactions in deep-sea vent chimneys. | the prokaryotic diversity of culturable thermophilic communities of deep-sea hydrothermal chimneys was analysed using a continuous enrichment culture performed in a gas-lift bioreactor, and compared to classical batch enrichment cultures in vials. cultures were conducted at 60 degrees c and ph 6.5 using a complex medium containing carbohydrates, peptides and sulphur, and inoculated with a sample of a hydrothermal black chimney collected at the rainbow field, mid-atlantic ridge, at 2,275 m depth. ... | 2007 | 17576518 |
| thermodesulfatator atlanticus sp. nov., a thermophilic, chemolithoautotrophic, sulfate-reducing bacterium isolated from a mid-atlantic ridge hydrothermal vent. | a novel, strictly anaerobic, thermophilic, sulfate-reducing bacterium, designated strain at1325(t), was isolated from a deep-sea hydrothermal vent at the rainbow site on the mid-atlantic ridge. this strain was subjected to a polyphasic taxonomic analysis. cells were gram-negative motile rods (approximately 2.4 x 0.6 microm) with a single polar flagellum. strain at1325(t) grew at 55-75 degrees c (optimum, 65-70 degrees c), at ph 5.5-8.0 (optimum, 6.5-7.5) and in the presence of 1.5-4.5 % (w/v) na ... | 2010 | 19648352 |
| sulfur-metabolizing bacterial populations in microbial mats of the nakabusa hot spring, japan. | at the nakabusa hot spring, japan, dense olive-green microbial mats develop in regions where the slightly alkaline, sulfidic effluent has cooled to 65°c. the microbial community of such mats was analyzed by focusing on the diversity, as well as the in situ distribution and function of bacteria involved in sulfur cycling. analyses of 16s rrna and functional genes (apra, pufm) suggested the importance of three thermophilic bacterial groups: aerobic chemolithotrophic sulfide-oxidizing species of th ... | 2011 | 21353426 |
