The ef?cienthydrolysis of cellulose into glucose for the mix-milledsample containing cellulose and CD-C catalyst in thiswork could be ascribed to the following two reasons On one hand as shown in Fig 2 the degree ofcrystallinity of the cellulose could be effectivelyreduced by the ball-milled operation and thus increasethe accessibility of the
What is the catalytic hydrolysis of cellulose?
ANN and RSM analyses revealed that the catalytic hydrolysis of cellulose using amorphous carbon bearing SO 3 H, OH and COOH groups proceeds in the same way as cellulose saccharification using conc. H 2 SO 4: the reaction depends strongly on the amount of water.
Can dimethyl sulfoxide be used as a biocatalyst in cellulose hydrolysis?
More interestingly, trace amounts of dimethyl sulfoxide was found to promote cellulase activity. This work provides a simple and practically method for promising applications as biocatalyst in cellulose hydrolysis and an effective strategy for the immobilization of other enzymes in green chemical industry.
How does acid hydrolysis affect sugar production?
During acid hydrolysis, an increase of time reaction improves reducing sugars production . In analyzing the relationship between sugar degradation and acid concentration, suggests that treatment are prone to degradation with increased acid concentration. Although enzymatic catalysts have advantages than acid.
