In fermentation process, if glucose is converted into ethanol then it is called ethanolic fermentation. Yeast Glucose Ethanol Bacillus acidilacti When glucose is converted into organic acids such as lactic acid, then this type of fermentation is known as lactic acid fermentation. It is carried out by the bacterium Bacillus acidilacti. Kuhne’s fermentation tube experiment Lactic acid Kuhne’s fermentation tube consists of an upright glass tube and a side tube with a bulb. 10 per cent glucose solution mixed with baker’s yeast is taken in the Kuhne’s tube and the tube is completely filled. After some time, the glucose solution is fermented and gives out an alcoholic smell. The level in the upright tube will fall due to the accumulation of CO 2 gas. It is because yeast contains the enzyme zymase which converts glucose solution into alcohol and CO 2. When a crystal of KOH is introduced into the tube, the KOH will absorb CO 2 and the level of the solution will rise in the upright tube. Self evaluation I . Choose and write the correct options. 1.
