Abstract

SUMMARY : A psychrophilic species of the genus was found to be capable of growth in a simple defined medium with any one of a number of carbon sources. The growth requirements were the same at 0° and 20°. The organism vigorously oxidized glucose to gluconic and 2-ketogluconic acids. Rates of O uptake were measured over the range 0–40° and compared with similar measurements on Under the experimental conditions values of for the psychrophile were higher than those for P. at all temperatures, including those above 30° at which temperatures the psychrophilic organism does not grow. The values of and their temperature coefficients were dependent on conditions of cultivation. It is concluded that the systems involved in the oxidation of glucose and gluconic acid by the two organisms may not be greatly different in those physical properties which determine their temperature relations.
