Predicting growth of Brochothrix thermosphacta at changing temperature.
A dynamic growth model was tested using Brochothrix thermosphacta incubated in broth at changing temperatures. The model successfully predicted growth in the temperature range 5-25 degrees C when temperature increased or decreased gradually and also when temperature underwent frequent sudden changes. When the temperature profile contained step changes from 20-25 degrees C to 3 degrees C the observed growth curve deviated from that predicted by the model.
