Presentation Transcript

  1. Fermentation Lab

  2. Fermentation Equation • C6H12O6 2C2H5OH + 2CO2 + 2 ATP • Glucose ethanol + carbon dioxide + 2 ATP

  3. Anaerobic vs. Aerobic • Anaerobic = without oxygen • C6H12O6 2C2H5OH +2CO2 +2 ATP Glucose ethanol + carbon dioxide +2 ATP • Aerobic = with oxygen

  4. Alcohol Fermentation • Must be airtight (or it will go into an aerobic respiration) • By yeast and some kinds of bacteria

  5. We’re Using Yeast • Saccharomyces Cerevisae. • Note Budding

  6. CO2 Produces Holes in Bread • Yeast product of carbon dioxide makes holes as it expands in the bread

  7. Water Bath: A beaker inside of a beaker • This keeps the water temperature even

  8. Ideal Growing Conditions 1. moisture 2. a temperature between 10 and 50ºC but ideally 30-37ºC 3. a food source such as sugar or flour • WATCH THE THERMOMETER!!!!! • Keep it in the beaker.

  9. Gas Collection Tubes • Take readings from tube • Holes already in lid • Invert in warm water to act as waste container for ethanol

  10. Running a little slow… • Sheldon will give your solution a boost… • (yeast loading) Dry Dormant Stage
