Degradation xylanase incubation

The catalytic action of the two avicelases and the cellobiohydrolase C seems at least to be different from those of the xylanases isolated from Trichoderma viride i.e., the degradation products have a higher degree of polymerization even after prolonged incubation and, in the case of sprucewood holocellulose, no arabinose is liberated. 

The addition of mannanase after 48 hr of incubation with one of the three cellulases revived cellulose hydrolysis. The increase of the degradation rate was not as pronounced as in the corresponding treatments of delignified beechwood with cellulases and xylanase (JO), but the cellulose degradation reached about the same values at the end of the experiments (about 50-65% ).
