The process used by some protists to actively ingest food particles is called Phagocytosis.ther protists like fungus grow  above their food source to get nutrients. Some protists engulf  bacteria and digest them internally, by extending their cell  membrane and forming a vacuole around the bacteria.
The purpose is to see if the microbe can use starch, a complex carbohydrate made from glucose, as a source of carbon and energy for growth.Use of starch is accomplished by an enzyme called alpha-amylase.lace the dropper above the plate and add the reagent to the culture. The starch in the plate is changed to blue-brown by the iodine reagent. Areas where starch has been digested by bacterial growth exhibit clear halos in the midst of the dark plate, indicating a positive alpha-amylase, or starch hydrolysis test.
