Four different strains of Saccharomyces cerevisiae yeast samples were β-and γ irradiated using a 90 Sr nuclear source. The samples were irradiated for five hours acquiring a 12 Gray irradiation doses. The irradiated and non-irradiated samples were subject to a fermentation process conducted at 28°C and pH=5.8 for 96h. The fermentation parameters (c...

... results of the fermentation activity, measured as CO 2 emission and the maltase activity measured at 24 hours interval are presented in table 3. The CO 2 emission at 24 hours interval is presented in figure 2 and the maltase activity in figure 3. Examining Table 1, figures 2 and 3 we notice that the fermentation process produced by the irradiated samples (batch having the suffix 2) is more intense, which is proved by the increased CO 2 emission and by the increased maltase activity. We can also conclude that for the all four Saccharomyces cerevisiae yeast strings the relatively low 12 Gray β -irradiation doses had a stimulating effect in respect of the fermentation process. ...
