A novel anaerobic, mesophilic, slightly halophilic sulfate-reducing bacterium, designated strain Khaled BD4(T), was isolated from waters of a Tunisian thermal spring. Cells were vibrio-shaped or sigmoids (5-7×1-1.5 µm) and occurred singly or in pairs. Strain Khaled BD4(T) was Gram-stain-negative, motile and non-sporulated. It grew at 25-45 °C (optimum 37 °C), at pH 5.5-8.3 (optimum pH 7.0) and with 0.5-8% NaCl (optimum 3%). It required vitamins or yeast extract for growth. Sulfate, thiosulfate… 

Figures and Tables from this paper

Halodesulfovibrio spirochaetisodalis gen. nov. sp. nov. and reclassification of four Desulfovibrio spp.

Integrated genomic and phenotypic data supported the classification of strain JC271T as a representative of a novel genus, for which the name Halodesulfovibrio spirochaetisodalis gen. nov. is proposed.

Establishment of Genome Based Criteria for Classification of the Family Desulfovibrionaceae and Proposal of Two Novel Genera, Alkalidesulfovibrio gen. nov. and Salidesulfovibrio gen. nov.

The genome-based criteria for classification of Desulfovibrionaceae were established and validated and it was confirmed that most strains display metal tolerance and five strains have the potential to be newly classified.

Relationship between true digestibility of dietary phosphorus and gastrointestinal bacteria of goats

It is recommended that the community of gastrointestinal microbiota is a factor affecting TDP in goats.

The Role of Thermal Water in Chronic Skin Diseases Management: A Review of the Literature

The current knowledge of the chemical, immunological, and microbiological basis for therapeutic effects of thermal water with a specific focus on chronic inflammatory skin diseases is reviewed and the potential role of balneotherapy either alone or as a complement to conventional medical treatments is discussed.



Desulfotomaculum hydrothermale sp. nov., a thermophilic sulfate-reducing bacterium isolated from a terrestrial Tunisian hot spring.

On the basis of genotypic, phenotypic and phylogenetic data, strain Lam5(T) represents a novel species of the genus Desulfotomaculum, for which the name Desulfotomyaculum hydrothermale sp.

Thermoanaerobacter subterraneus sp. nov., a novel thermophile isolated from oilfield water.

A new thermophilic, anaerobic glucose-fermenting, Gram-positive, rod-shaped bacterium, designated strain SEBR 7858T, was isolated from an oilfield water sample and designated as a new species, Thermoanaerobacter subterraneus sp.

Characterization of Microaerobacter geothermalis gen. nov., sp. nov., a novel microaerophilic, nitrate- and nitrite-reducing thermophilic bacterium isolated from a terrestrial hot spring in Tunisia

This isolate from the terrestrial hot spring of Hammam Sidi Jdidi, Nabeul, Tunisia is proposed to be assigned as a novel genus and a novel species within the domain Bacteria, Microaerobacter geothermalis gen. nov.

Thermotoga hypogea sp. nov., a xylanolytic, thermophilic bacterium from an oil-producing well.

It is proposed that strain SEBR 7054T is a member of a new species of the genusThermotoga, Thermotoga hypogea sp.

Studies on dissimilatory sulfate-reducing bacteria that decompose fatty acids

Gliding motility, ultrastructure and nutrition of two newly isolated filamentous sulfate-reducing bacteria, strains 5ac10 and 4be13, were investigated; the capacity of complete oxidation was shown by stoichiometric measurements with acetate plus sulfate.

Microbial diversity in Tunisian geothermal springs as detected by molecular and culture-based approaches

The diverse prokaryotic communities arising from the 12 geothermal hot springs studied are discussed and the findings are related to the physico-chemical features of the hot springs.

Hydrogen sulfide: a toxic gas produced by dissimilatory sulfate and sulfur reduction and consumed by microbial oxidation.

This review provides an examination of cytochromes, iron-sulfur proteins, and sirohemes participating in electron movement in diverse groups of sulfate-reducing, sulfur-red reducing, and sulfide-oxidizing Bacteria and Archaea.

The Roll-Tube Method for Cultivation of Strict Anaerobes

Habitats devoid of oxygen include the interior of the alimentary tracts of most mammals, the lower portions of many oligotrophic lakes, the sediment underlying bodies of water, and water logged soils, which are chiefly responsible for the lack of O2.
