Today, we inoculated a LOT of test tubes to test for a variety of things. We are testing for gelatin hydrolysis, fermentation of the carbohydrates glucose, sucrose and lactose with a Durham tube, a Methyl Red/Voges-Proskauer test for fermentation of mixed acids, a Triple Sugar Iron (TSI) Agar test to see if the bacteria produced hydrogen peroxide, and a Litmus milk test to determine if the bacteria will utilize lactose, protein or litmus.
