Abstract
The growth at 4 degrees, 10 degrees and 15 degrees C of six psychrotrophic yeasts isolated from foods was compared using total viable counts and ATP measurement. A linear relationship (r greater than or equal to 0.97) was obtained between log10 (number of viable yeasts) and log10 (ATP content) of cultures grown at these temperatures. This relationship was not temperature-dependent. The results are discussed and their significance for the rapid estimation of yeasts in foods is considered.
