The Effect Of Glucose Concentration On The Activity Of Various Yeasts Aim / Prediction - I intend to investigate what effect, if any, varying concentrations of a glucose solution has on the activity of two different types of yeasts. I predict that yeast activity will continue to rise as the concentration of the glucose solution increases, but will maybe have an optimum point at which the yeast can no longer withstand the high concentration in glucose. This applies to both of the yeasts, although I think that bread-making yeast will be more tolerant of glucose than brewers yeast. There will be a positive correlation between glucose concentration and yeast activity. Null Hypothesis (HO) - Varying glucose concentrations will have no effect on yeast activity. Alternative Hypothesis (H1) - Varying glucose concentrations will have no effect on yeast activity. Background - Yeast is any of a number of microscopic, unicellular fungi important for their ability to ferment...
