A solid medium containing ashed, acid-washed cellulose and a dye, Congo red, has been developed for enumeration of cellulose-utilizing bacteria in soil.

A vivid contrast between the uniform red color of the medium and these halos made this method of differentiation of these organisms superior to other methods.
