Linear oligosacchardies of 1,4 linked β-D-glucopyranose are commonly referred to as cellodextrins (CD) or cellooligosaccharides (CO). They are of interest to those working in disciplines involving cellulose chemistry because they are often used as model substrates for cellulose itself. They are of interest to food scientists and nutritionists because they...
The traditional filter paper assay for saccharifying cellulase
originally described by M. Mandels et al (1976) has been modified to
make possible low activity determinations of Trichoderma
cellulases. The enzymatic activity appears to decline during a
prolonged incubation period if no precautions have been taken. By
means of adding bovine...
