Halomonadaceae fam. nov., a New Family of the Class Proteobacteria to Accommodate the Genera Halomonas and Deleya
The branching point of the Halomonas-Deleya line of descent from other sublines in terms of similarity coefficients is as low as 0.45, which justifies the description of a new family, for which the name Halomonadaceae is proposed. Expand
A Methanogenic Archaeon from Ace Lake, Antarctica: Methanococcoides burtonii sp. nov.
A methylotrophic, methanogenic bacterium was isolated from the anoxic hypolimnion of Ace Lake, Antarctica, a lake with ionic composition similar to that of seawater, where a new species Methanococcoides burtonii is described and the type strain is DSM 6242. Expand
Effects of hydraulic retention time and sulfide toxicity on ethanol and acetate oxidation in sulfate‐reducing metal‐precipitating fluidized‐bed reactor
Ethan oxidation was more inhibited by sulfide toxicity than the acetate oxidation, and the noncompetitive inhibition model described well the sulfide inhibition of the sulfate‐reducing culture. Expand
Performance and Ethanol Oxidation Kinetics of a Sulfate-Reducing Fluidized-Bed Reactor Treating Acidic Metal-Containing Wastewater
The FBR process produced a good quality effluent as indicated by its low organic content and Zn and Fe concentrations below0.1 mg l -1, and the alkalinity produced from ethanol oxidation increased the wastewater pH from 2.5 to 7.5. Expand
Halobacterium lacusprofundi sp. nov., a Halophilic Bacterium Isolated from Deep Lake, Antarctica
The strains were not proteolytic, did not produce acids from sugars, but utilized a wide range of carbon sources including sugars, alcohols, and organic acids for growth, and grew at 4°C, albeit very slowly. Expand
Methanogenium frigidum sp. nov., a psychrophilic, H2-using methanogen from Ace Lake, Antarctica.
This is the first report of a psychrophilic methanogen growing by CO2 reduction, isolated from the perennially cold, anoxic hypolimnion of Ace Lake in the Vesfold Hills of Antarctica. Expand
Desulfosporosinus meridiei sp. nov., a spore-forming sulfate-reducing bacterium isolated from gasolene-contaminated groundwater.
Eight strains of spore-forming, sulfate-reducing bacteria isolated from groundwater contaminated with motor fuel in sandy soil near Perth, Australia, were closely related to Desulfosporosinus (previously Desulfotomaculum) orientis DSM 765T (95.3-97.3% 16S rDNA sequence similarity). Expand
Carbon isotopic fractionation associated with methylotrophic methanogenesis
Methanogenesis from “noncompetitive” substrates such as trimethylamine (TMA) and dimethylsulfide (DMS) may be quantitatively important in global methane budgets. This is because choline, glycineExpand
Direct sequencing of the polymerase chain reaction-amplified 16S rRNA gene of Flavobacterium gondwanense sp. nov. and Flavobacterium salegens sp. nov., two new species from a hypersaline Antarctic
Phenotypic data and phospholipid ester-linked fatty acid profiles indicate that pigmented bacterial strains isolated from a hypersaline Antarctic lake are members of the "flavobacterium-bacteroides" phylum and may represent new taxa and phylogenetic analysis showed that the Antarctic strains were phylogenetically distinct. Expand
Flavobacterium hibernum sp. nov., a lactose-utilizing bacterium from a freshwater Antarctic lake.
Four freshwater Antarctic lakes were examined for the presence of beta-galactosidase-producing bacteria using mineral medium enrichments and lactose and two strains were isolated that were very similar in phenotype and fatty acid profile, and shared considerable homology in their DNA. Expand
