Review various thermal death measurements by completing each sentence.
1. Adequate sterilization requires that both (Click to select) __________ and length of (Click to select) __________ be properly controlled.
2. In general, higher temperatures allow (Click to select) __________ exposure times, while lower temperatures require (Click to select) __________ exposure times.
3. In terms of these strategies, the (Click to select) __________ is defined as the shortest length of time required to kill all test microbes at a specified temperature.
4. Another optional measurement used to compare the susceptibility of microbes to heat is the (Click to selec__________) which is defined as the lowest temperature required to kill all microbes in a sample in 10 min (Click to select) __________
Possible answers:
dessication
exposure
longer
minimum inhibitory concentration
pH
shorter
temperature
thermal death point
thermal death time
Answer (2)
Adequate sterilization requires proper control of both temperature and exposure time. Higher temperatures enable shorter exposure times, while lower temperatures require longer exposure. Key measurements include thermal death time and thermal death point, which help in comparing microbial heat susceptibility. ;
The completion of the sentences about thermal death measurements requires controlling both temperature and exposure time for adequate sterilization. Higher temperatures allow for shorter exposure times, while thermal death time and thermal death point are key measurements in understanding microbial susceptibility to heat. These principles are fundamental for effective sterilization processes.
