Fig. 30.—Showing the action of different types of bacteria upon milk, a, the aerobic type {BacL aerogenes); 6, the anaerobic type {Bad. lacHs acidi); c and d, the peptonizing type, with the curd in different stages of digestion. and is consistent with the production of the best grades of butter and cheese. This organism grows readily at temperatures from 60° to ioo°F., growing more rapidly at higher temperatures. At a temperature of about 70° it grows with great rapidity, and at this temperature it seems to be more vigorous than any other bacterium ordinarily found in milk. For this reason, as we shall.
