and : New Molecular Markers for Phylogenetic and Biodiversity Studies of the Genus .

Currently, the phylogeny of the genus is based on comparative whole genome analysis because of the high homology of the 16S ribosomal RNA gene sequences within the genus. We analyzed the possibility of using various conservative genes as phylogenetic markers for the genus . We found that the levels of similarity of the nucleotide sequences of the tRNA(Ile)-lysidine synthase () and the β subunit of RNA polymerase () genes are in good agreement with the average nucleotide identity (ANI) values between the genomes of various representatives of the genus .

Comparative Genome Analysis of the Genus Involving Three Novel Species, sp. nov. Ku-5, sp. nov. AS and " Thiothrix anitrata" sp. nov. A52, Revealed the Conservation of the Pathways of Dissimilatory Sulfur Metabolism and Variations in the Genetic Inventory for Nitrogen Metabolism and Autotrophic Carbon Fixation.

Two strains of filamentous, colorless sulfur bacteria were isolated from bacterial fouling in the outflow of hydrogen sulfide-containing waters from a coal mine ( sp. Ku-5) and on the seashore of the White Sea ( sp. AS).

Reclassification of Sphaerotilus natans subsp. sulfidivorans Gridneva et al. 2011 as Sphaerotilus sulfidivorans sp. nov. and comparative genome analysis of the genus Sphaerotilus.

Filamentous iron oxides accumulating bacteria Sphaerotilus natans subsp. natans and S. natans subsp.

Genomic and Metabolic Insights into Two Novel Species from Enhanced Biological Phosphorus Removal Systems.

Two metagenome-assembled genomes (MAGs), obtained from laboratory-scale enhanced biological phosphorus removal bioreactors, were analyzed. The values of 16S rRNA gene sequence identity, average nucleotide identity, and average amino acid identity indicated that these genomes, designated as RT and SSD2, represented two novel species within the genus , ' Thiothrix moscowensis' and ' Thiothrix singaporensis'. A complete set of genes for the tricarboxylic acid cycle and electron transport chain indicates a respiratory type of metabolism.
