Question

Understand the purpose and function of the fluid thioglycollate tubes (including the indicator dye), brewer plates, and the anaerobic jar.

A) To identify the color of the organisms.
B) To support the growth of microorganisms.
C) To detect the presence of viruses.
D) To measure pH levels.

Answer 1

Fluid thioglycollate tubes are used to test oxygen sensitivity of bacteria, brewer plates support the growth of microorganisms, and anaerobic jars create an oxygen-free environment for anaerobic bacteria.

Step-by-step explanation:

The purpose and function of fluid thioglycollate tubes, brewer plates, and anaerobic jars in microbiology are:

1. Fluid thioglycollate tubes are used to observe the requirements for molecular oxygen and test the oxygen sensitivity of bacteria. The oxygen concentration varies throughout the tube, allowing bacteria to grow at different levels depending on their oxygen requirements.
2. Brewer plates provide a solid medium for bacterial growth and are used to support the growth of microorganisms. They contain nutrients like agar and are suitable for cultivating various bacteria and fungi.
3. Anaerobic jars create an oxygen-free environment to cultivate anaerobic bacteria. These jars typically contain a chemical mixture that reacts with the air to remove oxygen, creating conditions suitable for the growth of anaerobes.
