ABSTRACTWe investigated effects of atmospheric pressure dielectric barrier discharge (DBD) plasma irradiation on growth characteristics of bread yeast (Saccharomyces cerevisie). Nitric oxide of 400 ppm and O3above 200 ppm are produce by the DBD plasmas. DBD plasma irradiation of 50 and 100 s enhances the growth of yeast in the lag phase, whereas 150 s irradiation suppresses the growth. There is an optimum duration of plasma irradiation for the growth promotion.

Dielectric barrier discharge (DBD) plasma has been found to uniquely polymerize ribose that is not usually subject to polymerization since molecules that tend to polymerize almost always possess at least a π-bond. The polymer was analyzed via nuclear magnetic resonance (NMR) spectra, matrix-assisted laser desorption ionization time-of-flight (MALDI TOF) mass spectroscopy and Fourier-Transform inferred spectroscopy (FTIR), and it was found that dehydration occurs during polymerization.
