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 ...

Psychrophiles and polar regions
Current Opinion in Microbiology, 2002Most reviews of microbial life in cold environments begin with a lament of how little is known about the psychrophilic (cold-loving) inhabitants or their specific adaptations to the cold. This situation is changing, as research becomes better focused by new molecular genetic (and other) approaches, by awareness of accelerated environmental change in ...

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.

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 Spoilage Bacteria of Poultry
Journal of Applied Bacteriology, 1968SUMMARY The organisms most commonly found growing on poultry carcases stored at 1° are pigmented and nonpigmented strains of Pseudomonas, Pseudomonas putrefaciens and strains of Acinetobacter.

Conversion of Mesophilic to Psychrophilic Bacteria
Science, 1968The minimum temperature of growth of the mesophilic bacterium Pseudomonas aeruginosa has been significantly lowered from approximately 11° to 0°C. This shift in the minimum temperature of growth was accompanied by a corresponding decrease in the maximum temperature of growth.
