Article Synopsis
- Anaerobic, fermentative, and halotolerant bacteria strains 4-11 and 585 were isolated from production water in Russian low-temperature petroleum reservoirs using a detailed characterization method.
- These strains are spherical, non-motile, optimal at 35 °C, and can grow in saline conditions, primarily feeding on sugars with distinct cellular fatty acids and lipid profiles.
- Genetic analysis showed 99.9% similarity in their 16S rRNA sequences, leading to the proposal of a new species and the reclassification of related genera within a newly established family based on phylogenomic metrics.
An anaerobic alkaliphilic, proteolytic bacterium, strain Su22, was isolated from the bottom sediment of the alkaline low mineralization lake Sulphatnoe (Selenginsky district, Buryatia, Russia). A comparative analysis of the 16S rRNA gene sequence revealed that this bacterium was closely related to Anoxynatronum sibiricum Z-7981 with a similarity of 98.1 %.

Cells of the strain, designated Х-07-2T, were straight to slightly curved rods, Gram-stain-positive and motile. Strain Х-07-2T grew in the pH range from 7.

Bacterial cells were non-motile, spherical, ovoid and annular with diameter 0.2-4 μm.

The article presents data describing morphology, physiology, and biochemical characteristics of the isolated strains. These strains Ki4, Ki5, and Su2 were mesophilic and alkaliphilic with optimal growth at pH 8.
