Abstract
The upper temperature limit for growth of an enterotoxin A producing strain (MF31) and of an enterotoxin B producing strain (S6) was about 44-45 degrees C in either a peptone-based medium or heart infusion broth. In the presence of NaCl, growth and production of enterotoxin, coagulase, and thermostable nuclease occurred up to 2 degrees C higher. The optimal concentration of NaCl for the temperature elevation effect was 1 M.
摘要
在基于蛋白胨的培养基或心浸液肉汤中，产肠毒素A菌株（MF31）和产肠毒素B菌株（S6）生长的温度上限约为44 - 45摄氏度。在有氯化钠存在的情况下，肠毒素、凝固酶和耐热核酸酶的生长及产生可在高2摄氏度的温度下发生。产生温度升高效应的氯化钠最佳浓度为1M。
