You record the following results of a nitrate reductase broth that was inoculated with an unknown bacteria species and incubated for 48 hours. Step 1: Look for a gas bubble. There is a gas bubble. (You know that your unknown bacteria can ferment glucose. You are not sure if the gas is nitrogen gas or carbon dioxide gas, so you go onto step 2). Step 2: Add reagent A and B. There is no color change. Step 3: Add zinc. The broth turns red. What is your interpretation of this unknown bacteria? What type of gas is probably the product of this reaction and is in the Durham tube?
