Seven emetic toxin-producing strains of Bacillus cereus were examined for toxin production in Skim Milk Medium at incubation temperatures ranging from 10 to 50 degrees C. Minimum and maximum growth temperatures were found to be 12 and 46 degrees C, respectively. At 12 and 15 degrees C, levels of toxin production were significantly higher (P < 0.01) than that observed at 30 degrees C, while no toxin was produced above 37 degrees C. Increased levels of sporulation were observed at increased temperatures, and no correlation was found between levels of sporulation and toxin production (R(2) = 0.086).
对七株产呕吐毒素的蜡样芽孢杆菌菌株在脱脂乳培养基中进行检测，培养温度范围为10至50摄氏度。发现其最低和最高生长温度分别为12摄氏度和46摄氏度。在12摄氏度和15摄氏度时，毒素产生水平显著高于在30摄氏度时观察到的水平（P < 0.01），而在37摄氏度以上不产生毒素。随着温度升高，芽孢形成水平增加，且未发现芽孢形成水平与毒素产生之间存在相关性（R² = 0.086）。
