Mining thermophiles for biotechnologically relevant enzymes: evaluating the potential of European and Caucasian hot springs.

The development of sustainable and environmentally friendly industrial processes is becoming very crucial and demanding for the rapid implementation of innovative bio-based technologies. Natural extreme environments harbor the potential for discovering and utilizing highly specific and efficient biocatalysts that are adapted to harsh conditions. This review focuses on extremophilic microorganisms and their enzymes (extremozymes) from various hot springs, shallow marine vents, and other geothermal habitats in Europe and the Caucasus region.

Characterization of a Theme C Glycoside Hydrolase Family 9 Endo-Beta-Glucanase from a Biogas Reactor Metagenome.

From a biogas reactor metagenome an ORF (bp_cel9A) encoding a bacterial theme C glycoside hydrolase family 9 (GH9) enzyme was recombinantly produced in E. coli BL21 pQE-80L. BP_Cel9A exhibited ≤ 55% identity to annotated sequences.

Increased pain sensitivity in alcohol withdrawal syndrome.

Withdrawal from analgesic and addictive substances such as opioids or ethanol is associated with increased sensitivity to sensory stimulation in animal models. Here, we investigated perception of innocuous and noxious thermal or electric stimuli applied to the left hand or sternum in 30 male patients undergoing withdrawal from alcohol, 30 male abstained alcoholics and matched controls. The alcohol withdrawal scale and the Banger score were obtained to estimate the severity of withdrawal.
