• Biochemical tests are the kinds of tests that are done on different bacteria to figure out what kind of bacteria they are based on how they react to different biochemical compounds.
• Biochemical tests, which are usually done with phenotypic identification, are one of the traditional ways to figure out what kind of microorganism it is.
• These methods were widely used for a long time, and they are still used today, especially in some lab procedures where a certain type of microorganism needs to be identified quickly.
• Several biochemical tests are based on the ability of microorganisms to use certain biomolecules to make organic compounds that they can use.
• There are different kinds of biochemical tests, and different ways to tell the difference between different microorganisms.
• One of the older methods is to look for an increase in turbidity in the liquid medium. This shows that the organism is growing and getting the nutrients it needs.
• In other tests, on the other hand, the results are based on how the colour of the medium changes as its pH changes.
• Microorganisms can be put into different groups based on how they respond to these kinds of tests. Some tests can even tell the difference between different species of microorganisms.
• Because of this, biochemical tests are important because they are cheap and easy to do.
• The way bacteria and other microorganisms work is different from one another, which makes it possible to tell them apart.
• Biochemical tests, on the other hand, have some flaws. Even though these methods are cheap and can give both quantitative and qualitative information about the variety of microorganisms in a sample, they are difficult to use and take a long time to see results.
• Sometimes, false positives are found, especially when similar microbial species are being tested.

What is the purpose of biochemical test?

Biochemical tests are used to tell the difference between different types of bacteria based on how they behave in the biochemical world.

What are examples of biochemical tests?

• Catalase Test.
• Mannitol Salt Agar (MSA)
• Blood Agar Plates (BAP)
• Streak-stab technique.
• Taxos P (optochin sensitivity testing)
• Taxos A (bacitracin sensitivity testing)
• CAMP Test.
• Bile Esculin Agar.
