How are thermal death point and thermal death time different? - Thermal death point is the lowest temperature that kills all cells in a broth in 10 minutes. Thermal death time is the time required to completely sterilize a particular volume of liquid at a given temperature. Is moist heat more effective than dry heat? - Because of its ability to penetrate microbial cells, moist heat kills microogranisms by denaturing their proteins. Sterilization can be achieved at lower temperatures in a sh...
