| Abstract: | Effects of temperature and pH on the activities of protease,amylase,cellulase and lipase in testine of phascolosoma esculenta were studied by means of enzyme analyses.The results showed that temperature affected significantly the activities of protease,amylase,cellulase and lipase in testine of phascolosoma esculenta in 5～65 ℃ ranges.The optimum temperatures of protease,amylase,cellulase and lipase were 50 ℃,35 ℃,35 ℃ and 45 ℃,respectively.In our experiment,we designed the pH ranges for protease,lipase amylase,and cellulose were 5.6～10.4,4.4～9.2,2.4～9.2 and 2.4～9.2,respectively.The pH value affected significantly the activities of four digestive enzymes in testine of Phascolosoma esculenta in the designed pH ranges.The optimum pH of protease,amylase and lipase were 9.6,7.6 and 7.2,respectively.The optimum pH of cellulase were 4.4 and 8.4. |
