Catalase Activity of Psychrophilic Bacteria Grown at 2 and 30 C1

Abstract

Catalase activity of psychrophilic bacteria grown at 2 and tat 30 C. Appl. MIicrobiol. 11:151-153. 1963.-Catalase atctivity 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 plhysiological age, cells grown at 2 C had more catalase than cells grown at 30 C.

Similarity in Several Properties of Psychrophilic Bacteria Grown at Low and Moderate Temperatures1

“…Lipase activity of Pseudomonas fragi (13) and the lipase (1) and protease (14) activities of Pseudomonas fluorescens increased when cells were grown at low temperatures. Also we reported previously that the catalase activity of two psychrophilic pseudomonads was higher in cells grown at 2 C than in cells grown at 30 C (7).…”

“…MATERIALS AND METHODS Organisms. Pseudomonas strains 92 and 95, the psychrophilic cultures used in this study, were maintained as described previously (7).…”
