Electromagnetic field stimulation at low frequency (80 Hz, induced electric field: 0.11 mV/cm) has been studied in baker's yeast (Saccharomyces cerevisiae). 100 mg of yeast suspended in sucrose (5.8 x 10(-2) mol/L) and phosphate buffer (0.05 mol/L) were incubated at +36-degrees-C.

Abstract
Electromagnetic field stimulation at low frequency (80 Hz, induced electric field: 0.11 mV/cm) has been studied in baker's yeast (Saccharomyces cerevisiae). 100 mg of yeast suspended in sucrose (5.8 x 10(-2) mol/L) and phosphate buffer (0.05 mol/L) were incubated at +36-degrees-C. CO2 production was measured in normal and cold-stressed-yeast (-23-degrees-C for 12 h). Electromagnetic pulsed field was effective in stimulating CO2 production in treated (150.8 +/- 35.6-mu-l CO2/h/100 mg of yeast) compared to normal control (109.2 +/- 21.3-mu-l CO2/h/100 mg of yeast) cultures and in stressed and treated (145.0 +/- 33.5-mu-l CO2/h/100 mg of yeast) vs. stressed untreated samples (83.3 +/- 18.7-mu-l CO2/h/100 mg of yeast).
