Catalase Activity of Psychrophilic Bacteria Grown at 2 and 30 C¹

Department of Food Science and Technology, Hawaii Agricultural Experiment Station, University of Hawaii, Honolulu, Hawaii

ABSTRACT

Catalase activity was measured in resting-cell suspensions of psychrophilic bacteria grown at 2 and at 30 C. Enzyme activity decreased in both cell-suspension types as harvest age increased. At comparable physiological age, cells grown at 2 C had more catalase than cells grown at 30 C.
