Gliding motility, ultrastructure and nutrition of two newly isolated filamentous sulfate-reducing bacteria, strains 5ac10 and 4be13, were investigated. [...] Key Result The filaments were always attached to surfaces. Growth was supported by addition of insoluble aluminium phosphate or agar as substrata for gliding movement.Expand
Isolation and characterization of a nicotinic acid-degrading sulfate-reducing bacterium, Desulfococcus niacini sp. nov.
The strains NAV-1, NAV-2, NAV-3 of new nonsporing sulfate-reducing bacteria with spherical to oval motile cells were isolated with nicotinic acid as electron donor and carbon source. All strains wereExpand
Characterization of a new thermophilic sulfate-reducing bacterium
TLDR
The divergence in the 16S ribosomal RNA sequences between the new isolate and Thermodesulfobacterium commune suggests that these two thermophilic sulfate-reducing bacteria represent different genera, and these two bacteria depict a lineage that branches deeply within the Bacteria domain and which is clearly distinct from previously defined phylogenetic lines.

Fermentative degradation of glutarate via decarboxylation by newly isolated strictly anaerobic bacteria
TLDR
Two strains of new strictly anaerobic, gramnegative bacteria were enriched and isolated from a freshwater and a saltwater anoxic sediment with glutarate as sole energy source and a pathway of glutarate fermentation via decarboxylation of glutaconyl- CoA to crotonyl-CoA is suggested which forms butyrate and partly isobutyrate by subsequent isomerization. Expand
Desulfotomaculum geothermicum sp. nov., a thermophilic, fatty acid-degrading, sulfate-reducing bacterium isolated with H2 from geothermal ground water
TLDR
Strain BSD is proposed as a new species of the spore-forming sulfate-reducing genus Desulfotomaculum, D. geothermicum, which grew chemolithoautotrophically with hydrogen plus sulfate as energy source and carbon dioxide as carbon source without requirement of additional organic carbon like acetate. Expand
Desulfotoinaculum geothermicum sp . nov . , a thermophilic , fatty acid-degrading , sulfate-reducing bacterium { solated with H 2 from geothermal ground water t '
A strictly anaerobic, thermophilic, fatty acids-degrading, sporulating sulfate-reducing bacterium was isolated from geothermal ground water. The organism stained Gram-negative and formed gas vacuolesExpand
New motile anaerobic bacteria growing by succinate decarboxylation to propionate
TLDR
Three strains of new anaerobic, gram-negative bacteria which grew with succinate as sole source of carbon and energy were isolated from anoxic marine and freshwater mud samples, and moderate activities of avidin-sensitive methylmalonyl-CoA decarboxylase were found in cell-free extracts of all strains. Expand
Cytophaga xylanolytica sp. nov., a xylan-degrading, anaerobic gliding bacterium
TLDR
Results, which are discussed in terms of the current concept of the genus Cytophaga, suggest that the importance of C. xylanolytica in anaerobic biopolymer decomposition has not been fully appreciated. Expand
Desulfosporomusa polytropa gen. nov., sp. nov., a novel sulfate-reducing bacterium from sediments of an oligotrophic lake
TLDR
Five strains of sulfate-reducing bacteria were isolated from the highest positive dilutions of a most probable number (MPN) series supplemented with lactate and inoculated with sediments from the oligotrophic Lake Stechlin, revealing a new phylogenetic lineage of sulfating bacteria. Expand
A strictly anaerobic nitrate-reducing bacterium growing with resorcinol and other aromatic compounds
TLDR
With resorcinol as sole source of energy and organic carbon, two stains of gram-negative, nitrate-reducing bacteria were isolated under strictly anaerobic conditions and produced a compound identified as 5-oxo-2-hexenoic acid by mass spectrometric analysis, which would indicate a direct, hydrolytic cleavage of the res orcinol nucleus without initial reduction.

Methods for enrichment and pure culture isolation of filamentous gliding sulfate-reducing bacteria
TLDR
Multicellular gliding filaments were observed among high numbers of other bacteria on the bottom of anaerobic marine enrichment culture flasks with sulfate and acetate or benzoate as substrates and isolated as two new species of the new genus Desulfonema. Expand

Studies on Cytophaga fermentans, n.sp., a facultatively anaerobic lower myxobacterium.

  • 1955
TLDR
This organism is a typical non-fruiting, amicro-cystogenous lower myxobacterium and has been classified in the genus Cytophaga under the name C. fermentans to indicate its ability, unique among the cytophagas so far studied, to grow anaerobically at the expense of organic compounds. Expand
A new anaerobic, sporing, acetate-oxidizing, sulfate-reducing bacterium, Desulfotomaculum (emend.) acetoxidans
TLDR
A new strictly anaerobic, polarly flagellated, sporing, acetate-oxidizing, sulfate-reducing bacterium was isolated from anaerobe fresh or sea water mud samples and an emended description of the genus Desulfotomaculum is proposed which includes the new bacterium as the species Desulfotomyaculum acetoxidans. Expand
Capnocytophaga: New genus of gram-negative gliding bacteria I. General characteristics, taxonomic considerations and significance
TLDR
Given the guanine and cytosine content of DNA, their gliding motility, and the ability of many strains to attack polysaccharide a relationship to the cytophagas is suggested, and this relationship, along with the CO2-dependent growth is recognized by the generic name Capnocytophaga given them.

Oxidation of short-chain fatty acids by sulfate-reducing bacteria in freshwater and in marine sediments
TLDR
Anaerobic mineralization of acetate, propionate- and l-lactate-oxidizing sulfate-reducing bacteria in marine sediments was studied in the presence and in the absence of sulfate. Expand

TLDR
It is concluded that acetate oxidation with sulphate in D. postgatei proceeds via the citric acid cycle with the synthesis of pyruvate from acetyl CoA and CO2 as an anaplerotic reaction. Expand
