- Batch anaerobic fermentation experiments were performed to investigate the hydrolysis of cellulose into reducing sugars by bacteria and fungi found in the stomach of goats. The graph shows the results obtained at a range of pH values from 5.3 to 7.3.
(a) Suggest conclusions that the investigators drew from this data about the effect of pH on the cellulose hydrolysis rate. [2]
(b) Suggest one advantage of using microorganisms in this type of fermentation. [1]
(c) Distinguish between batch and continuous fermentation. [1]
