Figure 2From: A fast, sensitive and easy colorimetric assay for chitinase and cellulase activity detectionReproducibility of the ChitO-based assay with chitinase. Absorbance values of the ChitO-based assay from nine replicates of colloidal chitin treated for 1 hour with 50 μU of chitinase from Streptomyces griseus were plotted against nine replicates of untreated colloidal chitin under the same assay conditions. ChitO, chito-oligosaccharide oxidase.Back to article page
