Define Tests for the Presence of Exoenzymatic Activity?
Microorganisms require various micro- and macro-nutrients for energy production and growth. These are obtained from the environment. However, many of these are present in polymeric form, like starch, lipid, casein etc. which because of their high molecular weight and size are not able to enter in the cell. Microorganisms secrete exoenzymes to hydrolyze these macromolecules into respective building blocks to transport into the cell. Different microorganisms show different enzymatic activities.
