The rates of dipicolinic acid (Dpa) release and the rates of death were studied for spores of five strains of Bacillus stearothermophilus. It was observed that a highly significant relationship exists between the rate of Dpa release and rate of spore death for the four out of five strains tested and for all test temperatures. At 115 degrees C the rate of Dpa release was found to be faster than the rate of death, equal at 120 degrees C and slower at 125 degrees C. The role of Dpa in heat resistance was considered and a theory is proposed to explain the mechanism by which the heat resistance of bacterial spores is overcome.
对嗜热脂肪芽孢杆菌五株菌株的孢子进行了吡啶二羧酸（Dpa）释放速率和死亡速率的研究。观察到，在测试的五株菌株中的四株以及所有测试温度下，Dpa释放速率与孢子死亡速率之间存在高度显著的关系。在115摄氏度时，发现Dpa释放速率比死亡速率快，在120摄氏度时相等，在125摄氏度时较慢。考虑了Dpa在耐热性中的作用，并提出了一种理论来解释克服细菌孢子耐热性的机制。
