Inspection principle

Gelatin peptone and acid-hydrolyzed casein provide nitrogen sources; Glycerol provides a carbon source; Potassium sulfate and magnesium chloride can promote the production of pseudomonas pigment. AGAR is the coagulant of the culture medium. Naphthidine acid inhibits Gram-negative bacilli that are not Pseudomonas.
