Final answer:
When an organism is incubated in nitrate broth, the results can vary depending on the enzyme the bacteria produces. Nitrate can be reduced by bacteria to nitrite and other forms through the process of denitrification.
Step-by-step explanation:
When an organism is incubated in nitrate broth, the results can vary depending on the enzyme the bacteria produces. Nitrate can be reduced by bacteria to nitrite and other forms through the process of denitrification.
This can be tested using a nitrate reduction test, where a positive result indicates that the bacteria have reduced nitrate to nitrite, while a negative result indicates that the bacteria have further reduced nitrate to forms other than nitrite.
