《Predictive Modeling for Growth and Enterotoxin Production of Staphylococcus aureus in Milk》
1 MSE,Mean square error.Lower MSE,the more suitable,the model for describing growth data of Staphylococcus aureus.2 Bf,Bias factor.Bf>1 indicates a'fail-safe'model,while Bf<1 indicates a'fail-dangerous'model.3 Af,Accuracy factor.The larger the value
When compared the observed growth rate values with the values estimated by the three models(Fig.2),it showed that most parts of observed rate constant values were lower than predicted values generated from modified logistic model and modified Gompertz model,while observed values and predicted values from Baranyi model were fit well.The values of MSE,Bf and Af for growth rate listed in Table 1 also indicated that Baranyi model gave the best estimate for the rate constant of growth.Statistical analysis showed that MSE from Baranyi(0.0129±0.0015)was lower than that from modified Gompertz model(0.0294±0.0089)and modified logistic model(0.0298±0.0084)(p<0.05) .In addition,there was no statistical difference between MSE values of modified Gompertz model and modified logistic model(p>0.05).These comparisons showed that Baranyi model provided predictions were the most closely matched observed growth rate data than other two models.What was more,Bf of Baranyi model was close to one,which indicated good agreement between observed and predicted values;whereas,the values of Bf produced by modified logistic model and modified Gompertz model was more than 1,suggesting that the two models tended to give the&apos;fail-safe&apos;predictions(Ross et al.,2000).Values of Af for three models were also indicated that Baranyi model estimated more accurately than other two models.These results showed that Baranyi model described the growth curves of S.aureus in milk more accurately than those of modified logistic model and modified Gompertz model.Therefore,Baranyi model was employed in follow-up experiment.
