removal of arsenic from contaminated soils by microbial reduction of arsenate and quinone. | we investigated bioremediation of as-contaminated soils by reductive dissolution of as using a dissimilatory as(v)-reducing bacterium (darb), bacillus selenatarsenatis sf-1. we also examined the effect of anthraquinone-2,6-disulfonate (aqds), an extracellular electron-shuttling quinone, on the as extraction. when b. selenatarsenatis was incubated with as(v)-laden al precipitates, no acceleration of as dissolution was observed in the presence of aqds, even though the microbial reduction of aqds o ... | 2008 | 18767680 |
taxonomic description and genome sequence of bacillus campisalis sp. nov., a member of the genus bacillus isolated from a solar saltern. | the taxonomic position of a gram-stain positive bacterium isolated from a solar saltern sample collected from kanyakumari, coastal region of the bay of bengal, india, was analysed by using a polyphasic approach. the isolated strain, designated sa2-6t, had phenotypic characteristics that matched those of the genus bacillus. the 16s rrna gene sequence (1493 bases) of the novel strain was compared with those of previously studied bacillus type strains and confirmed that the strain belongs to the ge ... | 2015 | 26296567 |
bacillus canaveralius sp. nov., an alkali-tolerant bacterium isolated from a spacecraft assembly facility. | two gram-positive, rod-shaped, alkali-tolerant (ph 10.5), endospore-forming bacteria (strains ksc sf8bt and ksc sf10a) were isolated from surfaces within the payload hazardous servicing facility, where robotic spacecraft are assembled and tested before launch, at the kennedy space center at cape canaveral. based on 16s rrna gene sequence similarities, these strains were shown to belong to the family bacillaceae and the genus bacillus. the highest 16s rrna gene sequence similarity was approximate ... | 2009 | 19567559 |
bacillus selenatarsenatis sp. nov., a selenate- and arsenate-reducing bacterium isolated from the effluent drain of a glass-manufacturing plant. | a facultatively anaerobic, selenate- and arsenate-reducing bacterium, designated strain sf-1(t), was isolated from a selenium-contaminated sediment obtained from an effluent drain of a glass-manufacturing plant in japan. the bacterium stained gram-positive and was a motile, spore-forming rod capable of respiring with selenate, arsenate and nitrate as terminal electron acceptors. the major cellular fatty acids of the strain were iso-c(15 : 0), iso-c(17 : 1)omega10c and c(16 : 1)omega7c alcohol. t ... | 2007 | 17473259 |
molecular cloning and characterization of the srdbca operon, encoding the respiratory selenate reductase complex, from the selenate-reducing bacterium bacillus selenatarsenatis sf-1. | previously, we isolated a selenate- and arsenate-reducing bacterium, designated strain sf-1, from selenium-contaminated sediment and identified it as a novel species, bacillus selenatarsenatis. b. selenatarsenatis strain sf-1 independently reduces selenate to selenite, arsenate to arsenite, and nitrate to nitrite by anaerobic respiration. to identify the genes involved in selenate reduction, 17 selenate reduction-defective mutant strains were isolated from a mutant library generated by random in ... | 2011 | 21357486 |
draft genome sequence of bacillus selenatarsenatis sf-1t, a promising agent for bioremediation of environments contaminated with selenium and arsenic. | bacillus selenatarsenatis sp. nov. strain sf-1(t) is a promising agent for bioremediation of environments contaminated with selenium and arsenic. here, we report the draft genome sequence of this strain. | 2015 | 25614571 |
