Effect of Metal Ions on the Degradation and Adsorption of Two Cellobiohydrolases on Microcrystalline Cellulose

摘要: Ba ++ , Pb and Cd . The addition of Mn Ca (10 mM) during the hydrolysis Avicel PH 101 caused an increase in total reducing sugar (TRS) for CBH I by 142, 135, 114 percent, respectively. Those II increased 177, 175, 115 was most stimulatory metal ion, whereas Hg inhibitory ion. adsorption experiments were performed to investigate how influence on is related cellobiohydrolases cellulose.
