What Temperature Kills Yeast - Bob

WebHome - Biofuels & Distilled Spirits WebIn yeast, there is more than one type of enzyme involved in anaerobic respiration. This means that the yeast enzymes do not denature at the same time, so although yeast does have an overall optimum temperature, the decrease in the rate of respiration that occurs after this point is gradual, as the number of actives sites decreases. WebThe experiments tested yeast respiration in both, warm water at 42 degrees Celsius and at room temperature. The outcome of the experiment indicates the warm water is optimal for yeast respiration in comparison to cold water. Introduction culture of african americans family
