In the production of ethanol by fermentation, why is the process done at an optimal temperature of 30⁰C?So that the yeast is warm enough to catalyse the reaction between oxygen and sugar to produce ethanolTo prevent the reaction happening too quickly, leading to a dangerous build up of ethanolSo the yeast is warm enough to perform anaerobic respiration, but below the temperature at which the zymase enzyme would denatureTo increase the life span of the yeast, so the production doesn\'t have to be stopped often to replace themQuestion 7 of 14 Loading... 8.

What are the advantages/disadvantages of using the fermentation of glucose to manufacture ethanol.Advantages: Uses renewable resources, e.g sugar cane. Uses low temp and pressure therefore low energy input. Disadvantages: Uses batch process which is inefficient. Slow rate of reaction. Impure product.Advantages: Uses continuous process which is efficient. Uses renewable resources, e.g sugar cane. Pure product. Disadvantages: Slow rate of reaction. High temperature and pressure require high energy input .Advantages: Uses renewable resources, e.g sugar cane. Pure product. Disadvantages: Uses batch process which is inefficient.
