Staphylococcus aureus 2064 growth as affected by temperature and reduced water activity

Based on 247 growth data, the growth of 2064 in dependence on temperatures (8-50°C) and values (0.999-0.83) was described. Optimal values of at all studied temperatures were determined by using Gibson model. Its compatibility was confirmed by several statistical indices, . root mean square errors ( 0.003-0.138), standard errors of prediction ( 0.6-17.5). Cardinal values for growth ( =7.7°C, =40.6°C, =46.7°C, =0.808, =0.994, =1.97 1/h) were determined by using CM model with indices =0.071, =17.5%. Our findings can provide relevant growth information that can be used in exposure assessment or in validation of other data regarding the growth of this opportunistic pathogen in foods.
