";y";represents the concentration of enterotoxin(ng·mL-1),";x";represents the time of S.aureus growth(h).

SEA amount increased linearly with time even after S.aureus growing to the stationary phase and the linear,besides,correlation coefficients were all about 0.99 for all the experimental temperatures according to Table 2.By the linear regression analysis of SEA production curve,the time when the toxin began to be detected was at the cell concentration of 106 cfu·m L-1 at each temperature.S.aureus growth at constant temperature of 23℃was as an example shown in Fig.1.This result was consistent with previous studies(Fujikawa and Morozumi,2006).
