Abstract
The effect of storage temperature on growth rates of 8 psychrophilic organisms isolated from commercial pasteurized milk was studied. Optimum growth temperatures were 21-32[degree]C for 7 cultures, all members of the genus Pseudomonas. The 8th culture, identified as Flavobacterium arvilla, grew best at 10[degree]C and failed to grow at 32[degree]C. When the cultures were held at 5 or 10[degree]C a lag phase, generally of 24 hours, was found; at a higher storage temperature little or no lag phase was noticed.
