deferribacter thermophilus gen. nov., sp. nov., a novel thermophilic manganese- and iron-reducing bacterium isolated from a petroleum reservoir.	a thermophilic anaerobic bacterium, designated strain bmat (t = type strain), was isolated from the production water of beatrice oil field in the north sea (united kingdom). the cells were straight to bent rods (1 to 5 by 0.3 to 0.5 microns) which stained gram negative. strain bmat obtained energy from the reduction of manganese (iv), iron(iii), and nitrate in the presence of yeast extract, peptone, casamino acids, tryptone, hydrogen, malate, acetate, citrate, pyruvate, lactate, succinate, and v ...	1997	9103640
deferribacter desulfuricans sp. nov., a novel sulfur-, nitrate- and arsenate-reducing thermophile isolated from a deep-sea hydrothermal vent.	a novel anaerobic, heterotrophic thermophile was isolated from a deep-sea hydrothermal vent chimney at the suiyo seamount in the izu-bonin arc, japan. the cells were bent, flexible rods, with a single polar flagellum. growth was observed between 40 and 70 degrees c (optimum temperature: 60-65 degrees c; doubling time, 40 min) and between ph 5.0 and 7.5(optimum ph 6.5). the isolate was a strictly anaerobic heterotroph capable of using complex organic compounds (yeast extract, tryptone, peptone, c ...	2003	12807210
deferribacter abyssi sp. nov., an anaerobic thermophile from deep-sea hydrothermal vents of the mid-atlantic ridge.	two strains of thermophilic, anaerobic, chemolithoautotrophic bacteria, designated jr(t) and dr, were isolated from hydrothermal samples collected on the mid-atlantic ridge from the rainbow (36 degrees 16' n, 33 degrees 54' w) and menez gwen (37 degrees 50' n, 31 degrees 50' w) vent fields, respectively. cells of both isolates were short, straight- to vibrio-shaped, motile rods with one polar flagellum, and were gram-negative and non-sporulating. strain jr(t) was characterized in detail. it was ...	2003	13130062
microbial diversity and methanogenic potential in a high temperature natural gas field in japan.	microbial diversity and methanogenic potential in formation water samples from a dissolved-in-water type gas field were investigated by using 16s rrna gene libraries and culture-based methods. two formation water samples (of 46 and 53 degrees c in temperature) were obtained from a depth of 700 to 800 m. coenzyme f(420)-autofluorescence indicated that 10(3)-10(4) cells per ml of active methanogens were present, accounting for at least 10% of the total cell count. the 16s rrna gene sequence analys ...	2007	17265161
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
culture-dependent and -independent characterization of microbial communities associated with a shallow submarine hydrothermal system occurring within a coral reef off taketomi island, japan.	microbial communities in a shallow submarine hydrothermal system near taketomi island, japan, were investigated using cultivation-based and molecular techniques. the main hydrothermal activity occurred in a craterlike basin (depth, approximately 23 m) on the coral reef seafloor. the vent fluid (maximum temperature, >52 degrees c) contained 175 microm h2s and gas bubbles mainly composed of ch4 (69%) and n2 (29%). a liquid serial dilution cultivation technique targeting a variety of metabolism typ ...	2007	17921273
calditerrivibrio nitroreducens gen. nov., sp. nov., a thermophilic, nitrate-reducing bacterium isolated from a terrestrial hot spring in japan.	a moderately thermophilic, nitrate-reducing bacterium, strain yu37-1(t), was isolated from hot spring water from yumata, nagano, japan. cells of strain yu37-1(t) were strictly anaerobic, gram-negative, non-sporulating, motile by means of a single polar flagellum, vibrio-shaped and 1.4-2.0 microm long. the temperature and ph for optimum growth were 55 degrees c and ph 7.0-7.5, respectively. strain yu37-1(t) grew best in basal medium without the addition of nacl. acetate, pyruvate, lactate, fumara ...	2008	18599715
deferribacter autotrophicus sp. nov., an iron(iii)-reducing bacterium from a deep-sea hydrothermal vent.	a thermophilic, anaerobic, chemolithoautotrophic bacterium (designated strain sl50(t)) was isolated from a hydrothermal sample collected at the mid-atlantic ridge from the deepest of the known world ocean hydrothermal fields, ashadze field (1 degrees 58' 21'' n 4 degrees 51' 47'' w) at a depth of 4100 m. cells of strain sl50(t) were motile, straight to bent rods with one polar flagellum, 0.5-0.6 mum in width and 3.0-3.5 mum in length. the temperature range for growth was 25-75 degrees c, with an ...	2009	19502344
bacterial lifestyle in a deep-sea hydrothermal vent chimney revealed by the genome sequence of the thermophilic bacterium deferribacter desulfuricans ssm1.	the complete genome sequence of the thermophilic sulphur-reducing bacterium, deferribacter desulfuricans smm1, isolated from a hydrothermal vent chimney has been determined. the genome comprises a single circular chromosome of 2,234,389 bp and a megaplasmid of 308,544 bp. many genes encoded in the genome are most similar to the genes of sulphur- or sulphate-reducing bacterial species within deltaproteobacteria. the reconstructed central metabolisms showed a heterotrophic lifestyle primarily driv ...	2010	20189949
Mimivirus reveals Mre11/Rad50 fusion proteins with a sporadic distribution in eukaryotes, bacteria, viruses and plasmids.	The Mre11/Rad50 complex and the homologous SbcD/SbcC complex in bacteria play crucial roles in the metabolism of DNA double-strand breaks, including DNA repair, genome replication, homologous recombination and non-homologous end-joining in cellular life forms and viruses. Here we investigated the amino acid sequence of the Mimivirus R555 gene product, originally annotated as a Rad50 homolog, and later shown to have close homologs in marine microbial metagenomes.	2011	21899737
