Dielectric Spectroscopy of Pressurized Saccharomyces cerevisiae [PDF]
Food Biophysics, 2014 Results of broadband dielectric spectroscopy (BDS) in Saccharomyces cerevisiae (baker's yeast), in situ as the function of pressure are presented. They show a clear evidence of a threshold to the new pattern of the pressure evolution of the static dielectric permittivity and DC electric conductivity already for Pt ≈ 200MPa at T = 5 oC and Pt ≈ 300MPa
