The cellulosomal activity was found both in the harvest broth and the cell pellets. The cellulosome assembly was confirmed via the zymographic assay. The cellulosomal activities were larger than that of the respective free enzymes. The endoglucanase in the supernatant gave the best Vmax value of 8.98 mM/h. The endoglucanase of pellets has a better substrate affinity due to low Km value.
