摘要：

The aim of this study was to model the growth, in a model system, of toxigenic strains of Bacillus cereus as a function of temperature, pH and water activity. Optical density (OD) values were transformed into numbers of colony-forming units (CFU) by the use of a 'calibrating' relation. The growth curves were then fitted to the Gompertz function which allowed the estimation of the lag-time (lambda) and the growth rate (mu). These two parameters were then modelled according to the controlling factors which were pH and water activity at 20 and 30 degrees C. (C) 1997 Elsevier Science B.V.
