摘要：
Apparatus was constructed to subject colonies of bacteria, formed from single cells immobilized in solidified culture media contained between sheets of polymer, film to time-varying temperatures in the range 2-80 degrees C with rates of change of 1 degrees C s(-1). Results for the growth of Salmonella typhimurium LT2 in medium solidified with gelatin under sinusoidally-varying temperatures between 12 and 22 degrees C and of period 12 or 22 min are presented and were predictable by time-temperature integration using isothermal growth rates.
