Quizplus · Accepted Answer

Pasteurization by heating to 62.9 C for 30 minutes is not used for ensuring autoclaving has achieved sterility. Autoclaving typically involves heating to higher temperatures (usually around 121 C) for shorter periods of time (e.g. 15-20 minutes). Internal devices, such as thermometers and pressure gauges, may be used to monitor and maintain proper temperature and pressure during autoclaving. Tapes impregnated with the word "sterile" may be used to indicate when proper temperature has been reached. Autoclaving may also involve testing for sterility by autoclaving heat-resistant endospores such as Bacillus stearothermophilus, which are often used as a biological indicator.
