摘要：The influence of initial population size on destruction kinetics during milk pasteurization (63 °C/30 min) was studied relative to three Pseudomonas fluorescens isolates from pasteurized milk. The greatest reduction of viable cells was observed during first stage of milk pasteurization to reaching final temperature (63 °C/4 min) for all isolates and every starting population size. When inital population size attained <10^4 CFU/ml lethality determined immediately after pasteurization was 100%. Despite this fact viable cells were observed in all samples of pasteurized milk stored 48 hours at 7 °C.
