Dichlorane Glycerin Agar

from Wikipedia, the free encyclopedia

Dichlorane-Glycerol 18% Agar (DG18) is a nutrient medium with a "lower moisture content" that was developed in 1980 by AD Hocking and IJ Pitt. This can be used to determine the germ count of yeasts and molds that occur on dry surfaces. The 18% glycerine content binds the water and serves as a carbon and energy source. This promotes drought- loving ( xerophil ) or osmotolerant molds. The 2,6-dichloro-4-nitroaniline (dichlorane) inhibits fast-growing fungi, so that slow-growing species can also be detected. The addition of chloramphenicol inhibits bacterial growth.
