| A variety of other organic acids are produced by other bacteria, including butyric acid, responsible for the taste of rancid butter. |
| Most of the butyric class of bacteria are spore-bearing, and hence they are frequently present in boiled or sterilized milk. |
| During these changes a small quantity of gas is disengaged, no butyric acid is formed, and but little acetic or lactic acids. |
| The name comes from butyric acid, an acid that has the smell of rancid butter. |
| The flavor of the fat is due to the presence of a small amount of butyrin, which is an ethereal salt of butyric acid. |
| Undigested lactose fermented by bacteria creates lactic acid in the stool and other short chain fatty acids such as butyric acid. |
