What is the durham fermentation tube? |
[Edit] |
A Durham fermentation tube is a test tube that has a second inverted tube inside used to capture fermented gas byproducts of bacteria. Typically the tube has a pH indicator in it, like phenol red, that will change color when acid is present (in this case to yellow). Gases are trapped inside the Durham tube, while the indicator shows the production of acid.
