Abstract
A simple and accurate technique for the determination of the heat resistance of spores is described. The technique combines a modified capillary tube method with a solid heating block. The come-up time of spore suspensions was found to be short and simple and accurate technique is suggested for the correction of the come-up times. Experimental results are presented for the destruction of spores of Bacillus stearothermophilus at 120 degrees which indicates the accuracy and reproducibility of the new method.
摘要
本文描述了一种用于测定孢子耐热性的简单且准确的技术。该技术将改进的毛细管法与固体加热块相结合。发现孢子悬浮液的升温时间短，并且提出了一种简单准确的技术来校正升温时间。给出了嗜热脂肪芽孢杆菌孢子在120摄氏度下被破坏的实验结果，这表明了新方法的准确性和可重复性。
