Application Notes
Cellobiose is used in microbiological and phytopathological media as a carbon source for selection of specific microbes. It is used in multiple selection media, including mD5A Medium (Prod # M5516) and CCM medium. The table below is an example of the use of cellobiose as a carbon source in a selection medium.

The semi-selective medium designated as Cefazoline-Cellobiose-Methionine (CCM) medium is intended to select for Xanthomonas axonopodis pv. vignicola and contains the following components per liter (Wydra et al., 2004):
