Tadokoro : On the Antagonism between two different Salts in the Enzymatic Actions. 



227 



40 ccm of 1,0% solution of soluble starch were mixed with 1,0 com of 0,05 "/(, 

 Takadiastase solution and with the following quantities of different salts and 

 placed in a thermostat at 40° C under the presence of 2 ccm toluol. After 6 hours 

 20 ccm of these mixed solution were treated in the same way as above mentioned 

 and the results are as follows : 



Table 2. 



From the above results of my experiment we know that the enzymatic action 

 is evidently injured in the i/io normal concentration of Mg- or Ca- salts and in 

 the normal solution of alkalisalts. 



2 The antagonistic action between KCl 

 and CaCl2 for two amylases 



50 ccm of 1,0% soluble starch solution were mixed with 5 ccm of fresh juice 

 of wheet-seedling or with 5 ccm of o, 05 % Takadiastase solution, and the concen- 

 tration of salts in the solution was kept as follows.
