Laterally transferred elements and high pressure adaptation in Photobacterium profundum strains

BMC Genomics, 2005
Background Oceans cover approximately 70% of the Earth's surface with an average depth of 3800 m and a pressure of 38 MPa, thus a large part of the biosphere is occupied by high pressure environments.

A Programmable Eukaryotic Argonaute Nuclease with Dual DNA and RNA Cleavage Activity from Thermophilic Fungus Thermochaetoides thermophila

Small Science, Volume 6, Issue 3, March 2026.
This work demonstrates a unique eukaryotic Argonaute nuclease, TtpAgo, from Thermochaetoides thermophila DSM 1495 that can be programmed with either DNA or RNA guides and can cleave both DNA and RNA targets at mesophilic temperatures in vitro. TtpAgo binds 12–30 nt long 5′P or 5′OH guide molecules without strict sequence specificity, thus provides a ...

Exploring the Piezophilic Behavior of Natural Cosolvent Mixtures

Angewandte Chemie, 2011
Proteins are only marginally stable and are hence very sensitive to environmental conditions, such as high and low temperatures or high hydrostatic pressures. In nature, living organisms are able to compensate for extreme environmental conditions and hence rescue proteins from denaturation by using osmolytes.

Genetic Manipulations of the Hyperthermophilic Piezophilic Archaeon Thermococcus barophilus [PDF]

Applied and Environmental Microbiology, 2014
ABSTRACT In this study, we developed a gene disruption system for Thermococcus barophilus using simvastatin for positive selection and 5-fluoroorotic acid (5-FOA) for negative selection or counterselection to obtain markerless deletion mutants using single- and double-crossover events.

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

FEBS Letters, Volume 599, Issue 23, Page 3417-3443, December 2025.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

The Reduction of Skin Photodamage by the Ectoine–Thermus thermophilus Cofermentation Products

Journal of Cosmetic Dermatology, Volume 24, Issue 7, July 2025.
ABSTRACT Background Prolonged exposure to UVB (280–320 nm) can lead to skin oxidative damage, inflammatory response, and skin cancer. Many active ingredients in the fermentation products of Thermus thermophilus have been shown to play important roles in antioxidant and anti‐UVB photodamage, such as superoxide dismutase (SOD) and photolyase. Ectoine, as

Extremophilic Microorganisms as a Source of Emerging Enzymes for the Food Industry: A Review

Food Science &Nutrition, Volume 13, Issue 1, January 2025.
Enzymes such as amylases, lipases, proteases, xylanases, laccases, pullulanase, chitinases, pectinases, esterases, isomerases, and dehydrogenases could be derived from extremophilic organisms like thermophiles, psychrophiles, acidophiles, alkaliphiles, and halophiles. These enzymes or extremozymes are applicable in the production of safe foods (such as
