原始语种摘要: Aims: Cronobacter sakazakii has been associated most frequently with illness in neonates. This study aims to model effect of temperature on growth of a C. sakazakii isolate (IFST082014). Methodology: Reconstituted powdered infant milk formulas (RIMFs) inoculated with C. sakazakii were incubated at 10, 20, 30 and 40°C. Results: The primary model showed a good fit (r2 = 0.9714–0.9821) to a Gompertz equation to obtain growth rates and lag times (LTs) at each temperature. The specific growth rate (SGR) of C. sakazakii in the RIMF increased, and the LT decreased with increasing temperature. The secondary model was “ln SGR = -0.05879+(0.00588 x temperature)+(0.00045 x temperature2).” The SGR predicted using this model increased with an increasing temperature. This secondary polynomial model was...
