| shewanella marisflavi sp. nov. and shewanella aquimarina sp. nov., slightly halophilic organisms isolated from sea water of the yellow sea in korea. | two gram-negative, motile, non-spore-forming, rod-shaped organisms, strains sw-117(t) and sw-120(t), were isolated from sea water of the yellow sea in korea and subjected to a polyphasic taxonomic study. strains sw-117(t) and sw-120(t) simultaneously contained both menaquinones (mk) and ubiquinones (q) as isoprenoid quinones; the predominant menaquinone was mk-7 and the predominant ubiquinones were q-7 and q-8. the major fatty acid detected in the two strains was iso-c(15 : 0). the dna g+c conte ... | 2004 | 15545482 |
| shewanella loihica sp. nov., isolated from iron-rich microbial mats in the pacific ocean. | a novel marine bacterial strain, pv-4(t), isolated from a microbial mat located at a hydrothermal vent of loihi seamount in the pacific ocean, has been characterized. this micro-organism is orangey in colour, gram-negative, polarly flagellated, facultatively anaerobic and psychrotolerant (temperature range, 0-42 degrees c). no growth was observed with nitrate, nitrite, dmso or thiosulfate as the electron acceptor and lactate as the electron donor. the major fatty acid detected in strain pv-4(t) ... | 2006 | 16902030 |
| electricity generation at high ionic strength in microbial fuel cell by a newly isolated shewanella marisflavi ep1. | increasing the ionic strength of the electrolyte in a microbial fuel cell (mfc) can remarkably increase power output due to the reduction of internal resistance. however, only a few bacterial strains are capable of producing electricity at a very high ionic strength. in this report, we demonstrate a newly isolated strain ep1, belonging to shewanella marisflavi based on polyphasic analysis, which could reduce fe(iii) and generate power at a high ionic strength of up to 1,488 mm (8% nacl) using la ... | 2010 | 19789866 |
| shewanella corallii sp. nov., a marine bacterium isolated from a red sea coral. | a marine bacterial strain, designated fav-2-10-05(t), was isolated from the mucus layer of a coral of the genus favia, collected from the coral reef in the gulf of eilat, israel (29.5 ° n 34.9 ° e). on the basis of 16s rrna gene sequence comparisons, strain fav-2-10-05(t) was affiliated with the family shewanellaceae. the closest relatives of strain fav-2-10-05(t) were shewanella marisflavi sw-117(t) (96.0 % 16s rrna gene sequence similarity) and shewanella haliotis dw-1(t) (95.9 %). strain fav- ... | 2010 | 19915103 |
| biological characteristics and pathogenicity of a highly pathogenic shewanella marisflavi infecting sea cucumber, apostichopus japonicus. | shewanella marisflavi isolate ap629 is described as a novel pathogen of sea cucumber. the ld(50) values (14 days) in sea cucumber, mice and swordtail fish were 3.89 × 10(6) , 6.80 × 10(4) and 4.85 × 10(4) cfu g(-1) body weight, respectively. studies on s. marisflavi were conducted, including morphology, physiological and biochemical characteristics, haemolysis, whole-cell protein and 16s rdna gene sequence. colonies of s. marisflavi appeared faint red on marine agar and green on thiosulphate-cit ... | 2010 | 21039606 |
| decolorization of azo dyes by marine shewanella strains under saline conditions. | azo dye decolorization was studied with shewanella strains under saline conditions. growing cells of shewanella algae and shewanella marisflavi isolated from marine environments demonstrated better azo dye decolorization capacities than the other three strains from non-saline sources. cell suspensions of s. algae and s. marisflavi could decolorize single or mixed azo dyes with different structures. decolorization kinetics were described with michaelis-menton equation, which indicated better deco ... | 2013 | 22707057 |
| azo dye decolorization by a halotolerant exoelectrogenic decolorizer isolated from marine sediment. | based on both capabilities of extracellular electron transfer and high salt tolerance, marine exoelectrogenic bacteria have the potential to serve as halotolerant/halophilic exoelectrogenic decolorizers (heds) for textile wastewater treatment. however, research in this area is still rare. in this study, we employed shewanella marisflavi ep1 for this purpose. the results showed that ep1 could decolorize xylidine ponceau 2r (xp2r) under high nacl concentrations up to 20%. two different mechanisms ... | 2016 | 27239968 |
| biotransformation of 2,4-dinitrotoluene by obligate marine shewanella marisflavi ep1 under anaerobic conditions. | anaerobic transformation of 2,4-dnt by obligate marine shewanella marisflavi ep1 was investigated. the cell growth of ep1 was proportional to the total amount of 2,4-dnt reduced. the eventual transformation product was 2,4-diaminotoluene, via 2-amino-4-nitrotoluene and 4-amino-2-nitrotoluene as intermediates. the presence of cu(2+), dicumarol, metyrapone and flavins intensively influenced the reduction activity of 2,4-dnt, suggesting that dehydrogenease, menaquinone, cytochromes and flavins are ... | 2015 | 25603529 |
