摘要：

A novel apparatus has been designed for the investigation of the thermal inactivation of micro‐organisms over the temperature range 20–90d̀C. It comprises a stainless steel coil fully submerged in a thermostatically‐controlled water bath which allows very rapid temperature equilibration of microbial suspensions. Automated repeat sampling is possible at short time intervals (variable between 6 and 999 s) by means of an electronically controlled displacement mechanism. Validation of the apparatus performance and typical death curves are described. Copyright © 1990, Wiley Blackwell. All rights reserved
