Title: Growth and respiration of an obligate psychrophile, <i>Micrococcus cryophilus</i>, and its mesophilic mutants
Abstract: The temperature characteristic for growth (μ) has been determined for an obligate psychrophile, Micrococcus cryophilus ATCC 15174, and its mesophilic mutants. The use of μ. for characterizing psychrophiles and mesophiles is discussed.Solute-transporting and energy-yielding systems were shown to be unrelated to maximum growth temperature.Endogenous respiration and the temperature characteristic of substrate oxidation were both found to be unsuitable as a means of characterizing mesophiles and psychrophiles. The temperature coefficient of substrate oxidation (Q 10 ), with reference temperatures set at 10 and 30 °C is suggested for this purpose, mesophiles having a higher value than psychrophiles.
