[Dependence of microwave produced heating of cell suspensions on their concentration].
The kinetics of microwave (7 GHz) heating of yeast and bacterial cell suspensions of different concentrations was investigated in the conditions of various thermoisolation of irradiated samples. It was established that independently of type of microorganisms, microwaves produced a more intensive heating of cell suspension in comparison with suspension fluid. The degree of heating was shown to increase with cell concentration. This effect was more expressed under conditions of thermoisolation. At the same irradiation doses and cell concentrations the yeast suspension was heated more vigorously than bacterial one. These differences disappeared when the rise in sample temperature was related to the total cell volume.
