the agar used to detect the presence of lipase is:
spirit blue
nutrient gelatin
skim milk
starch agar

Explanation:

Spirit blue agar is specifically formulated to detect lipase activity. Lipase breaks down lipids, and in spirit blue agar, this breakdown causes a color change (a halo around the colonies due to the reaction of the released fatty acids with the spirit blue dye). Nutrient gelatin is for detecting gelatinase (enzyme that breaks down gelatin). Skim milk agar is for caseinase (enzyme that breaks down casein in milk). Starch agar is for amylase (enzyme that breaks down starch).

Answer:

Spirit blue
