N2 - 1. 1. The optimal pHs of the following enzymes were determined: sucrase, 6.4; maltase, 5.4-7.6; trehalase, 6.0; salicin hydrolase, 6.4. 2. 2. The optimal temperatures of sucrase, maltase and cellobiase were found to be 40°C and those of trehalase and salicin hydrolase were above 45°C. 3. 3. The highest activation energy was obtained with sucrase, followed by cellobiase, trehalase, salicin hydrolase and maltase. 4. 4. In all glycosidases studied, there were many more enzymes in the lumen than in the tissues of the gut.
