Two bacterial isolates from water of the alkaline brackish Lake Solenoe (Buryatia, Russia), 2C and 5C T , were characterized by using a polyphasic taxonomic approach. The strains were small, non-motile, Gram-stain-negative rods that formed small orange-red colonies on the surface of marine agar. Studies based on 16S rRNA gene sequences showed that the strains were related closely to Belliella pelovolcani CC-SAL-25 T (98.7 % sequence similarity). The G+C content of the DNA was 38-40 mol%.

... hybridization values between strains 2C and 5C T and B. pelovolcani CC-SAL-25 T were 56-58 mol%. A menaquinone with seven isoprene units (MK-7) was the major respiratory quinone. The fatty acid profiles were slightly different from that of B. pelovolcani CC-SAL-25 T . The novel strains could be distinguished from the phylogenetically closest species B. pelovolcani CC-SAL-25 T based on matrix-assisted laser desorption ionization time-of-flight mass spectra of whole cells and a range of physiological and biochemical characteristics. The data obtained suggest that strains 2C and 5C T represent a novel species of the genus Belliella, for which the name Belliella buryatensis sp. nov. is proposed. The type strain is 5C T (5VKM B-2724 T 5KCTC 32194 T ). Abbreviation: MALDI-TOF, matrix-assisted laser desorption ionization time-of-flight. The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain 5C T is LK021687. Three supplementary tables are available with the online Supplementary Material.
