Photodermatology, Photoimmunology &Photomedicine, Volume 42, Issue 5, September 2026.ABSTRACT Background/Purpose Visible light (VL), and particularly high‐energy visible light (HEVL), reaching Earth's surface has emerged as a relevant contributor to skin damage. VL has been implicated in oxidative stress, inflammation, pigmentation disorders, and photoaging, especially in individuals with darker skin phototypes.

Ectoine degradation pathway in halotolerant methylotrophs
PLOS ONE, 2020 Microorganisms living in saline environments are forced to regulate turgor via the synthesis of organic osmoprotective compounds. Microbial adaptation to fluctuations in external salinity includes degradation of compatible solutes. Here we have examined the biochemical pathway of degradation of the cyclic imino acid ectoine, the major osmoprotector in ...

Effects of ectoine on animals and humans [PDF]
Medycyna Weterynaryjna, 2019 Some species of soil bacteria and most organisms living in extreme environments such as salt lakes or coal or salt mines have effective protective mechanisms that enable them to function under adverse conditions. A common way to protect against harmful environmental factors is the production and accumulation of substances with an osmoprotective ...

Temperature and Ultraviolet Radiation Influence the Skin Microbiome of Humpback Whales
Molecular Ecology, Volume 35, Issue 15, August 2026.ABSTRACT The skin microbiome of humpback whales harbours diverse microbial communities that play a crucial role in host skin protection and environmental interaction. However, studies on cetacean skin microbiomes in the Southern Hemisphere focus on feeding grounds, with limited information on microbiome dynamics at breeding grounds and during migration

Global Change Biology, Volume 32, Issue 7, July 2026.A factorial rainfall × warming field experiment showed that drought and warming suppressed overall soil respiration but amplified rewetting‐induced CO2 pulses via contrasting effects of moisture, temperature, and substrate availability. Their interaction shifted seasonally, from additive (spring) to antagonistic (summer‐autumn) and synergistic (winter),

Kineochelins—A New Group of Siderophores From an Antarctic Bacterium
Microbial Biotechnology, Volume 19, Issue 6, June 2026.Genome‐guided analysis of an Antarctic Actinokineospora strain led to the discovery of kineochelins, a new group of siderophores involved in iron sequestration and microbial competition. Kineochelin production inhibits co‐occurring bacteria and clinically relevant yeasts, highlighting Antarctic microorganisms as promising sources of bioactive natural ...

Osmoadaptation in rhizobia: ectoine-induced salt tolerance [PDF]
Journal of Bacteriology, 1994 After having shown that ectoine (a tetrahydropyrimidine) displays osmoprotective properties towards Escherichia coli (M. Jebbar, R. Talibart, K. Gloux, T. Bernard, and Blanco, J. Bacteriol. 174:5027-5035, 1992), we have investigated the involvement of this molecule in the osmotic adaptation of Rhizobium meliloti. Ectoine appeared almost as effective as

Biotechnology and Bioengineering, Volume 123, Issue 3, Page 776-784, March 2026.The probiotic E. coli Nissle 1917 was engineered to enable stable and antibiotic free protein expression platforms using native plasmids. Further modification aids in the production of high‐level protein expression for antimicrobial secretion whose activity is comparable to industry standard E. coli BL21.
