Article Synopsis
- Phylogenetic analysis of bacteria from the Dead Sea and West Antarctic utilized 16S rRNA gene sequences, identifying key species like Bacillus licheniformis and psychrotolerant bacteria from Galindez Island.
- Two strains, a thermotolerant Staphylococcus sp. and various species of Frondihabitans, were discovered in unique habitats, emphasizing their ecological isolation and diversity in extreme environments.
- The study highlighted that Frondihabitans strains were the most common among the aerobic chemoorganotrophic bacteria in Antarctic ecosystems, showcasing their adaptability.
The aerobic chemoorganotrophic bacteria, dominating in soils and phytocenosis of the Antarctic Region, on combination of morphological and biochemical properties belong to several taxons of Bacteria domain. Gram-negative strains 3189, 3415 (fam. Halomonadaceae, Halomonas sp.

Resistance to these factors of the microorganisms isolated from ecosystems of this region (vertical steep gorge around the Dead Sea, clay-salt plain and black highly mineralized muds) is studied. Aerobic, chemoorganotrophic, thermotolerant, moderately halophilic bacteria which, according to their morphological and physiological properties, are similar to species Gracilibacillus halotolerans, Salimicrobium album and genus Caryophanon have been isolated from these ecosystems.

At cultivation in a periodic operation the maximum level of absolutely dry biomass in five tested strains constituted 3.2-7.

Article Synopsis
- The study aimed to investigate how cytokine gene expression changes during the cultivation of leukocytes from healthy donors.
- RNA from leukocytes was analyzed at different time points (0, 3, and 24 hours), focusing on 8 cytokine genes using PCR techniques.
- Results showed that after 3 hours, gene expression for pro-inflammatory cytokines peaked, while expression levels of anti-inflammatory cytokines remained stable over 24 hours.
