Figure 7.1
A suspension of 10 6 Bacillus cereus endospores was put in a hot- air oven at 170°C. Plate counts were used to determine the number of endospores surviving at the time intervals shown.

-In Figure 7.1, what is the thermal death time?

Quizplus · Accepted Answer

The thermal death time is the time needed to kill all microorganisms at a certain temperature. In Figure 7.1, it can be observed that all endospores were killed after 60 minutes at 170°C. Therefore, the thermal death time for this suspension of endospores is 60 minutes at 170°C.
