EXPERIMENTAL DATA 



The results obtained in the different experiments both as regards the 

 maceration in the solutions and in a water suspension of the mycelium 

 are represented graphically in figures i and 2. Each of the vertical lines 

 of a single group represents the results obtained for a particular organism 

 in a single experiment. The length of the vertical lines indicates the

Fig. 2.— Graph showing the time required by the differeut Rhizopus species to completely macerate 

 sweet-potato disks by the enzym contained in Yi gr. of the mycelium; also the comparative rate of macera- 

 tion iu the three experiments, 



length of time in hours required to complete maceration of the disks, 

 I cm. being equivalent to one hour. From these figures a direct com- 

 parison can be made of the results obtained from the different species as 

 well as the variation in the results of the same species in different experi- 

 ments.
