| phylogenetic positions of desulfofustis glycolicus gen. nov., sp. nov., and syntrophobotulus glycolicus gen. nov., sp. nov., two new strict anaerobes growing with glycolic acid. | the glycolate-oxidizing, sulfate-reducing bacterium strain perglys and the syntrophically glycolate-oxidizing bacterium strain flglyr were studied with respect to their phylogenetic relationships on the basis of in vitro amplification and direct sequencing of 16s rrna-encoding dna. strain perglys clustered with representatives of the delta subclass of the class proteobacteria, close to "desulforhopalus vacuolatus" but sufficiently distinct to preclude its assignment to this genus. these organism ... | 1996 | 8863436 |
| elemental sulfur and thiosulfate disproportionation by desulfocapsa sulfoexigens sp. nov., a new anaerobic bacterium isolated from marine surface sediment. | a mesophilic, anaerobic, gram-negative bacterium, strain sb164p1, was enriched and isolated from oxidized marine surface sediment with elemental sulfur as the sole energy substrate in the presence of ferrihydrite. elemental sulfur was disproportionated to hydrogen sulfide and sulfate. growth was observed exclusively in the presence of a hydrogen sulfide scavenger, e.g., ferrihydrite. in the absence of a scavenger, sulfide and sulfate production were observed but no growth occurred. strain sb164p ... | 1998 | 9435068 |
| sulfidogenesis from 2-aminoethanesulfonate (taurine) fermentation by a morphologically unusual sulfate-reducing bacterium, desulforhopalus singaporensis sp. nov. | a pure culture of an obligately anaerobic marine bacterium was obtained from an anaerobic enrichment culture in which taurine (2-aminoethanesulfonate) was the sole source of carbon, energy, and nitrogen. taurine fermentation resulted in acetate, ammonia, and sulfide as end products. other sulfonates, including 2-hydroxyethanesulfonate (isethionate) and cysteate (alanine-3-sulfonate), were not fermented. when malate was the sole source of carbon and energy, the bacterium reduced sulfate, sulfite, ... | 1999 | 10427015 |
| desulfomusa hansenii gen. nov., sp. nov., a novel marine propionate-degrading, sulfate-reducing bacterium isolated from zostera marina roots. | the physiology and phylogeny of a novel sulfate-reducing bacterium, isolated from surface-sterilized roots of the marine macrophyte zostera marina, are presented. the strain, designated p1t, was enriched and isolated in defined oxygen-free, bicarbonate-buffered, iron-reduced seawater medium with propionate as sole carbon source and electron donor and sulfate as electron acceptor. strain p1t had a rod-shaped, slightly curved cell morphology and was motile by means of a single polar flagellum. cel ... | 2001 | 11760947 |
| analysis of the sulfate-reducing bacterial and methanogenic archaeal populations in contrasting antarctic sediments. | the distribution and activity of communities of sulfate-reducing bacteria (srb) and methanogenic archaea in two contrasting antarctic sediments were investigated. methanogenesis dominated in freshwater lake heywood, while sulfate reduction dominated in marine shallow bay. slurry experiments indicated that 90% of the methanogenesis in lake heywood was acetoclastic. this finding was supported by the limited diversity of clones detected in a lake heywood archaeal clone library, in which most clones ... | 2003 | 12788715 |
| composition and dynamics of sulfate-reducing bacteria during the waterflooding process in the oil field application. | the composition and dynamics of sulfate-reducing bacteria (srb) during the waterflooding process of daqing oilfield were investigated in this study. pcr-dgge analysis indicated that the microbial communities were significantly different in each treatment unit, and the dominant members were mainly close to clostridium sp., thauera sp., hydrogenophaga sp., pseudomonas sp., eubacterium sp. and arcobacter sp. however, the members belonging to srb were relatively few and mainly consisted of desulfovi ... | 2010 | 20005702 |
| abundance and diversity of biofilms in natural and artificial aquifers of the äspö hard rock laboratory, sweden. | six cores were drilled and retrieved from 186-m depth in the äspö hard rock laboratory (hrl) tunnel to investigate whether indigenous biofilms develop on fracture surfaces in groundwater-conducting aquifers in granitic rock. a clone library was constructed from fracture surface material (fsm), for community composition analysis. quantitative polymerase chain reaction (qpcr) was applied to quantify gene copies using the 16s rrna gene for domain bacteria and the adenosine-phosphosulfate reductase ... | 2010 | 21132427 |
| microbial community of sulfate-reducing up-flow sludge bed in the sani(®) process for saline sewage treatment. | this study investigated the microbial community of the sulfate-reducing up-flow sludge bed (srusb) of a novel sulfate reduction, autotrophic denitrification, and nitrification integrated (sani®) process for saline sewage treatment. the investigation involved a lab-scale sani® system treating synthetic saline sewage and a pilot-scale sani® plant treating 10 m(3)/day of screened saline sewage. sulfate-reducing bacteria (srb) were the dominant population, responsible for more than 80% of the chemic ... | 2011 | 21494868 |
