Thermo Fisher, CM0061B, Peptone Water (Andrade) (Dehydrated)

Quantity: 500 g
Unit Size: Each
Peptone Water Andrade's is a nutrient base containing Andrade's indicator to which carbohydrates and other diagnostic reagents may be added for use in fermentation studies. The biochemical identification of organisms capable of growing in this medium is made by observing the catabolism of the various carbohydrates added to separate tubes of peptone water. To detect fermentation, which is the production of acid and gas, a small, inverted tube (Durham fermentation tube) is inserted into the peptone water to trap any gas produced by the organism. A single bubble in the tube is sufficient to label the organism positive. Some organisms will utilize the sugar to produce acid only, without gas formation.
