The Effect of Convallaria Root Concentration on the Rate of Fermentation

Total CO2 Evolved by Different Concentrations of Convollaria roots. Actual values are the graduated pipette readings. For CO2 evolved values, subtract the initial reading from the actual reading. This is the amount of CO2 accumulated over time. | Time (min) | Tube 1 | Tube 2 | Tube 3 | Tube 4 | | Actual | CO2 Evolved | Actual | CO2 Evolved | Actual | CO2 Evolved | Actual | CO2 Evolved | | (A) | (A-I) | (A) | (A-I) | (A) | (A-I) | (A) | (A-I) | Initial reading (I) | 0.05 | | 0.01 | | 0.02 | | 0.05 | | 2 | 0.16 | -0.84 | 0.12 | -0.88 | 0.19 | -0.81 | 0.23 | -0.77 | 4 | 0.24 | -0.76 | 0.5 | -0.5 | 0.37 | -0.63 | 0.36 | -0.64 | 6 | 0.3 | -0.7 | 0.54 | -0.45 | 0.49 | -0.51 | 0.5 | -0.5 | 8 | 0.45 | 0.55 | | | 0.61 | -0.39 | 0.62 | -0.38 | 10 | n/a | n/a | | | 0.73 | -0.27 | 0.75 | | 12 | | | | | | | | | 14 | | | | | | | | | | | | | | | | | |

Discussion

In this experiment, the amount of CO2 evolved for different concentrations of Convollaria roots was studied. The question being answered was what kind of effect the increase in concentration of Convollaria roots had on the rate of fermentation. The hypothesis was that the antimicrobial activities in Convallaria majalis’s roots would hinder the process of yeast fermentation because it will cause self- destruction or death in the microorganism of the yeast. If the antimicrobial activities in Convallaria majalis’s inhibit yeast fermentation, then the amount of CO2 evolved in the fermentation process will slowly decease or no CO2 will be formed. However, the results did not confirm our prediction because the Convallaria produced an increasing amount of CO2. Thus, the plants extract increased the rate of yeast fermentation.
There may be several reasons why the Convallaria roots yielded a fast rate of fermentation, instead of inhibiting the amount of CO2 evolved. One reason is that the Convallaria Majalis roots contain
