  • Title: Conversion of mesophilic to psychrophilic bacteria.
    Author: Olsen RH, Metcalf ES.
    Journal: Science; 1968 Dec 13; 162(3859):1288-9. PubMed ID: 4972441.
    Abstract:
    The minimum temperature of growth of the mesophilic bacterium Pseudomonas aeruginosa has been significantly lowered from approximately 11 degrees to 0 degrees C. This shift in the minimum temperature of growth was accompanied by a corresponding decrease in the maximum temperature of growth. Transfer of this genetic characteristic by a transducing phage grown on a psychrophile or by ultraviolet mutagenesis was used to accomplish these shifts in range of growth temperature.
