SECRETION OF DIASTASE BY PENICILLIUM CAMEMBERTII 239 
the complete transformation of the maltose to glucose. With malt 
diastase,^ however, it was found that o.i g. of diastase produced no 
evident hydrolysis of 0.3 g. of maltose in 7 hours at 24° C. With malt 
diastase as the hydrolyzing agent, therefore, a direct comparison could 
be made between diastatic action as measured by the maltose pro- 
duced and diastatic action as measured by the material precipitated 
in 73 percent acid alcohol.

About 0.175 g. of malt diastase (Merck's medicinal) was dissolved 
in 20 CC. of water, and after being filtered to remove all undissolved 
particles this solution was added to 1,750 cc. of a 2 percent (approxi- 
mate) starch solution. The mixture was kept in a constant tempera- 
ture oven at 24° C, but was removed from the oven and replaced 
each time a determination was made. The data obtained are sum- 
marized in Table II : 
It is evident that the digestion measured by alcoholic precipitation 
is greater than that measured by the maltose produced. In other 
words, a certain fraction of the digestion products is not maltose and 
^ Merck's medicinal.
