Abstract This experiment analyzes the effects of how temperature affects bacterial and fungus amylase and also discovers the optimum temperature for these enzymes. The amylase was mixed with starch at temperatures of 0℃‚ 37℃‚ 57℃‚ and 90℃. Iodine was added to each mixture and colour changes in each case. Bacteria amylase was found to be effective at 55 0C as the temperature dropped drastically from 4.58℃ to 2.33℃. This shows that the amylase catabolized a lot of starch hence little is left which
