Thermal Death Time TDT of Bacteria - Microbes can be partially or completely eliminated by heat treatment. However, the time and temperature used are dependent on the type and number of microorganisms.
Vegetative cells of yeast and fungi are not very heat resistant and are generally killed at temperatures of 50-70°C. Vegetative cells of thermophiles and thermo resistant organisms are resistant to these temperatures. Yeast ascospores and most mold spores are also inactivated at 60°C in 10-15 minutes.
