Micro-organisms of Maple Sap 303 



31. Number 31 was inoculated with gray yeast CXXI. 

 The organism was not recovered, hut the plates showed a count 

 of 5,667,000 colonics per cc. in which those of the fluorescent 

 group greatly predominated. The sirup contained 96.62% suc- 

 rose and 0.30' < invert sugar. The color was 6, flavor 2 and 

 score 825 ; depreciation from control, color 2, flavor o, and 

 score 50. 



32. Number 32 was inoculated with gray yeast CLXXX. 

 The organism was not recovered. The plates showed a count 

 of 5,600,000 colonies per cc, most of which were of the green 

 fluorescent type. The sirup contained 95.91% sucrose and 

 0.46% invert sugar. The color was 6, flavor 2, and score 825 ; 

 depreciation from control, color 2, flavor 0, and score 50. 



33. Number 33 was inoculated with gray yeast CLXVIII. 

 The organism was not recovered. The plates showed 1,950,000 

 colonies per cc. most of them characteristic of the fluorescent 

 organisms. The sirup contained 95.61% sucrose and 0.23% 

 invert sugar. The color was 7, flavor 2, and score 800, depre- 

 ciation from control, color 3, flavor o, and score 75. 



34. Number 34 was the control previously mentioned as 

 having been heated to 40 C, and placed in the incubator. As 

 would be expected the sap promptly clouded, developing a green 

 type of souring. The plates showed a count of 7,312,000 or- 

 ganisms per cc. Fluorescence was pronounced. The sirup con- 

 tained 95.86% sucrose and 0.42% invert sugar. The color was 6, 

 flavor 2 1 , and score 800; depreciation from cold control, color 2, 

 flavor o 1 , and score 75. 



35. Number 35 was inoculated with red yeast CXI. Deep 

 clouding developed and the organism was recovered in associa- 

 tion with large numbers of fluorescent bacteria. The plates 

 showed a count of 2,255,000 organisms per cc. The sirup con- 

 tained 95.13% sucrose and 1.15% invert sugar. The color was 

 12, flavor 2 1 , and score 650; depreciation from control, color 8, 

 flavor o 1 , and score 225.
