Article Synopsis
- Thermodesulfovibrio is a genus of thermophilic sulfate-reducing bacteria, currently recognized to have five species.
- Two new strains, 3907-1M and 3462-1, were isolated from hot springs, demonstrating the ability to use hydrogen and acetate for growth, with strain 3907-1M also showing autotrophic growth potential, a first for this genus.
- Genomic and phylogenomic analyses led to the classification of these strains as new species, indicating that the Thermodesulfovibrio genus has previously underestimated ecological flexibility and metabolic capabilities.
One of the important current issues of bioenergetics is the establishment of the thermodynamic limits of life. There is still no final understanding of what is the minimum value of the energy yield of a reaction that is sufficient to be used by an organism (the so-called "biological quantum of energy"). A reasonable model for determination of the minimal energy yield would be microorganisms capable of living on low-energy substrates, such as acetogenic prokaryotes.

Aims: To assess the changes in glomerular filtration rate (GFR) after living donation, and assess the parameters associated with it.
The genome of sp. strain 4228-Ro, an aerobic thermophilic bacterium isolated from a Kamchatka hot spring, was sequenced and analyzed. The genome assembly comprises 13 contigs with a total length of 3,068,448 bp.

At the same time, the very first 16S rRNA gene sequence-based phylogenetic studies of representatives of the genus pointed out great differences between Thermodesulfobium and other members of the phylum Bacillota. Subsequent studies of new Thermodesulfobium representatives supported deep phylogenetic branching of this lineage within bacterial tree, implying that it represents a novel phylum.
