A method was developed to deposit a visible layer of
water-insoluble compounds via sublimation onto the surface of solid
media. The compound is sublimed from a heated aluminum dish containing the compound onto the surface of an inverted, ice-cooled, inoculated agar petri dish. The method results in the deposition of a thin, even
layer on the agar surface without the use of solvent. After incubation,
clearing zones around colonies indicate the presence of
compound-degrading microorganisms.
