Homework Answers
1. The test shown is known as lipid hydrolysis test. This test is carried out to test the organisms ability to degrade lipids by excreting extracellular esterase enzyme.
2. Organism which secrets enzyme degrades surrounding lipids and hence clear zone is observed. In the above figure, organism B is positive as we see clear zone around the colonies.
3. The one which doesn't secretes enzyme doesn't show any clear zone. In the above figure, organism A is negative.
4. Esterase or lipases enzyme secretion extracellularly is tested in this experiment.
5. The function of the enzyme is degradation of lipids present in the media (tributyrin agar).
