The immobilization isotherms of Clostridium thermocellum cells on bituminous coal particles of approximately 0.15- to 0.18-mm diameter were experimentally measured at 60, 45, and 30 degrees C with a pH value of 7.0 and with pH values of 6.0 and 5.0 at 60 degrees C. The immobilization data were correlated into Langmuir forms and their characteristic coefficients were obtained. A method to obtain thermodynamic quantities delta G, delta H, and delta S for the immobilization is also demonstrated.
