*Data from this study.
The cell viability, expressed as a percentage, was calculated by direct counting the colony forming units present on the plates. The data are mean values, with errors being the standard deviation (SD). Results are representative of 3 independent experiments. N/A: not available. The control samples were subjected to conventional heating using a Peltier plate method; this heating method resulted in approximately 95% viability.
