Characterization of a New Bifunctional and Cold-Adapted Polysaccharide Lyase (PL) Family 7 Alginate Lyase from Flavobacterium sp.

Marine Drugs, 2020
Alginate oligosaccharides produced by enzymatic degradation show versatile physiological functions and biological activities. In this study, a new alginate lyase encoding gene alyS02 from Flavobacterium sp. S02 was recombinantly expressed at a high level

Low-Temperature Biodegradation of Lignin-Derived Aromatic Model Monomers by the Cold-Adapted Yeast Rhodosporidiobolus colostri Isolated from Alpine Forest Soil

Microorganisms, 2022
The contribution of cold-adapted yeasts to the emerging field of lignin biovalorization has not yet been studied. The red-pigmented basidiomycetous yeast strain Rhodosporidiobolus colostri DBVPG 10655 was examined for its potential to degrade five ...

Response to Cold: A Comparative Transcriptomic Analysis in Eight Cold-Adapted Yeasts

Frontiers in Microbiology, 2022
Microorganisms have evolved to colonize all biospheres, including extremely cold environments, facing several stressor conditions, mainly low/freezing temperatures.

The Protective Efficacy of Single-Dose Nasal Immunization with Cold-Adapted Live-Attenuated MERS-CoV Vaccine against Lethal MERS-CoV Infections in Mice

Vaccines, 2023
Middle East respiratory syndrome coronavirus (MERS-CoV) causes severe diseases in humans. Camels act as intermediate hosts for MERS-CoV. Currently, no licensed vaccine is available for this virus.

Molecular basis of cold adaptation [PDF]

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2002
Cold–adapted, or psychrophilic, organisms are able to thrive at low temperatures in permanently cold environments, which in fact characterize the greatest proportion of our planet. Psychrophiles include both prokaryotic and eukaryotic organisms and thus represent a significant proportion of the living world. These organisms produce cold–evolved enzymes

Psychrophily and Catalysis

Biology, 2013
Polar and other low temperature environments are characterized by a low content in energy and this factor has a strong incidence on living organisms which populate these rather common habitats.

Biochemical Properties of a Cold-Active Chitinase from Marine Trichoderma gamsii R1 and Its Application to Preparation of Chitin Oligosaccharides

Marine Drugs, 2023
The enzymatic degradation of different chitin polymers into chitin oligosaccharides (COSs) is of great significance given their better solubility and various biological applications.

Complete Lipooligosaccharide Structure from Pseudoalteromonas nigrifaciens Sq02-Rif^r and Study of Its Immunomodulatory Activity

Marine Drugs, 2021
Lipopolysaccharides (LPS) are surface glycoconjugates embedded in the external leaflet of the outer membrane (OM) of the Gram-negative bacteria. They consist of three regions: lipid A, core oligosaccharide (OS), and O-specific polysaccharide or O-antigen.

Characteristics of glucose and lipid metabolism and the interaction between gut microbiota and colonic mucosal immunity in pigs during cold exposure

Journal of Animal Science and Biotechnology, 2023
Background Cold regions have long autumn and winter seasons and low ambient temperatures. When pigs are unable to adjust to the cold, oxidative damage and inflammation may develop.

Histamine and Cold Adaptation

Experimental Biology and Medicine, 1963
SummaryRats exposed to cold (6°C) for one month show a very rapid and sustained increase in urinary histamine. At the end of this period animals develop a certain tolerance to histamine aerosols. This modification in histamine excretion in the cold possibly reflects mast cell changes and the decreased sensitivity to this amine in cold adapted animals ...
