A phenol red glucose broth with a Durham tube has been inoculated and incubated. After 48 hours, the broth is turbid and bright yellow and approximately half of the contents of the Durham tube contains bubbles. Interpret these results. The organism will ferment lactose as well. The organism is fermenting glucose. The organism is an obligate anaerobe. The organism is fermenting lactose and producing ethanol and CO2. What can be detected using SIM medium? Check all...

Questions
Experiment 2: TSI The triple sugar iron agar (TSI) can identify gram negative bacteria based on how they metabolize carbohydrates. It contains three carbohydrates-glucose, lactose and sucrose, in addition to sodium thiosulfate which some bacteria use in the production of hydrogen sulfide (H2S). It also contains iron in the ferrous form and phenol red as a pH indicator. TSI is poured into a tube when heated to a liquid form, and the tube is slanted as...

1. Someone new is preparing media for lab and adds buffers to the EMB agar that raise the pH to 7.8. The starting pH of EMB plates should be 6.9 – 7.3. No one is aware of the change. The EMB plates are inoculated for identification of unknown bacteria. After the appropriate incubation time, the results are interpreted. A. Discuss the consequences of the change in starting pH to the interpretation of the results. (The answer is not that no...
