The CBMs listed here include: Cellulomonas fimi CBM4-1 and CBM4-2 (CfCBM4-1 and CfCBM4-2), Clostridium cellulovorans CBM17 (CcCBM17), Bacillus sp. 1139 CBM28 (BspCBM28), and Clostridium josui CBM28 (CjCBM28). The methods for obtaining binding affinities in the referenced study are listed as either isothermal titration calorimetry (ITC), fluorescence emission scans, or ultraviolet (UV) difference spectra.
