The thermal death time is
WebA similar parameter, the thermal death time (TDT), is the length of time needed to kill all microorganisms in a sample at a given temperature. These parameters are often used to describe sterilization procedures that use high heat, such as autoclaving. WebThermal death time (TDT) adalah waktu yang dibutuhkan untuk membunuh suspensi sel atau spora pada suhu tertentu. Karena faktor yang bermacam-macam seperti pH, kelembapan, medium, dan umur sel sangat menentukan hasil, variabel ini harus dijabarkan dengan jelas.
