A psychrophilic yeast, isolated from decomposing Laminaria found on the beach at Hebron Fjord in Labrador, was shown to be a species of Cryptococcus, closely resembling but not identical with C. mucorugosus and C. terricolus. In a glucose–salts–vitamins medium, the yeast grew most rapidly at 25 °C, although the final cell crop was greatest in cultures ...

Psychrophiles can be defined as the members of the kingdom Monera thriving permanently at the lowest temperature range. Since the majority of our planet is generally cold, psychrophiles are common within a wide range of habitats. Extensive research in the field of genomics, transcriptomics, and proteomics revealed that psychrophiles are endowed with ...

Biomethanation under psychrophilic conditions
Waste Management, 2010The biomethanation of organic matter represents a long-standing, well-established technology. Although at mesophilic and thermophilic temperatures the process is well understood, current knowledge on psychrophilic biomethanation is somewhat scarce.

Psychrophilic enzymes: a thermodynamic challenge
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1997Psychrophilic microorganisms, hosts of permanently cold habitats, produce enzymes which are adapted to work at low temperatures. When compared to their mesophilic counterparts, these enzymes display a higher catalytic efficiency over a temperature range of roughly 0-30 degrees C and a high thermosensitivity.

Enzyme Catalysis in Psychrophiles
2017Cold-active enzymes are produced by organisms, known as psychrophiles, adapted to permanently cold habitats. Low temperatures have an exponential deleterious effct on reaction rates, and thus psychrophilic enzymes have to be adapted to secure appropriate reaction rates in their environment.

Catalytic Adaptation of Psychrophilic Elastase
Biochemistry, 2018The class I pancreatic elastase from Atlantic salmon is considered to be a cold-adapted enzyme in view of the cold habitat, the reduced thermostability of the enzyme, and the fact that it is faster than its mesophilic porcine counterpart at room temperature. However, no experimental characterization of its catalytic properties at lower temperatures has

Psychrophilic and psychrotrophic microorganisms
Experientia, 1986Psychrophilic and psychrotrophic microorganisms have the ability to grow at 0 degree C. Psychrotrophic microorganisms have a maximum temperature for growth above 20 degrees C and are widespread in natural environments and in foods. Psychrophilic microorganisms have a maximum temperature for growth at 20 degrees C or below and are restricted to ...

Psychrophilic Spoilage Bacteria of Fish
Journal of Applied Bacteriology, 1968SUMMARY Sterile press juice from raw muscle of cod and ethylene oxide — sterilized cod muscle blocks were used to determine the spoilage potential of representative bacterial species present on cod, and to ascertain the incidence of spoilers on whole gutted fish during storage in ice.
