Review of Desulfotomaculum species and proposal of the genera Desulfallas gen. nov., Desulfofundulus gen. nov., Desulfofarcimen gen. nov. and Desulfohalotomaculum gen. nov.
TLDR
The results of phylogenetic analysis demonstrated that the genus Desulfotomaculum already has lost the clustering monophyly and was segregated into some distinct groups with low sequence similarity.Abstract:
The genus
Desulfotomaculum
is a heterogeneous group of spore-forming sulfate-reducing bacteria. The type species of the genus is
Desulfotomaculum
nigrificans (Approved Lists 1980) emend. Visser et al. 2014. The results of phylogenetic analysis demonstrated that the genus
Desulfotomaculum
already has lost the clustering monophyly and was segregated into some distinct groups with low sequence similarity. Major features of the type strains in these groups were compared, and four novel genera, Desulfallas gen. nov., Desulfofundulus gen. nov., Desulfofarcimen gen. nov. and Desulfohalotomaculum gen. nov. were proposed to accommodate species transferred from the genus

TL;DR: The ability of microorganisms to colonize and concurrently reduce magnetite likely stimulated by the observed methanogenic benzoate degradation is shown, explaining the possible contribution of organoclastic reduction of iron oxides to the elevated dissolved Fe2+ pool typically observed in methanic zones of rapidly accumulating coastal and continental margin sediments.

Effect of sulfate addition on carbon flow and microbial community composition during thermophilic digestion of cellulose
TL;DR: Despite the strong impact of sulfate addition on the carbon flow and the microbial community structure during thermophilic biogas production, short-term process disturbances caused by unexpected introduction of sulfates may be overcome due to the high resilience of the engaged microorganisms.

Sediment cooling triggers germination and sulfate reduction by heat‐resistant thermophilic spore‐forming bacteria

TL;DR: Thermophilic endospores are widespread in cold marine sediments where the temperature is too low to support growth and activity of thermophiles in situ, and heat-resistant endospore-forming sulfate-reducing bacteria have a survival advantage if they are introduced to, or are resident in, an oil reservoir normally too hot for germination and growth.

TL;DR: In this article , a 2 2 central composite rotational design (CCRD) and response surface methodology (RSM) was used to assess the impacts of bicarbonate and sulfate availability on the establishment of sulfidogenesis in the thermophilic fermentation of vinasse in batch reactors.

TL;DR: This article proposes rational taxonomic boundaries for high taxa of bacteria and archaea on the basis of 16S rRNA gene sequence identities and suggests a rationale for the circumscription of uncultured taxa that is compatible with the taxonomy of cultured bacteria and Archaea.

TL;DR: 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.
