Los sustratos comunmente utilizados para el estudio de las endoglucanasas son carboximetilcelulosa y celulosa amorfa tratada con H3PO4 o alcali, su accion se caracteriza por la disminucion de la viscosidad como consecuencia de los clivajes intermoleculares; mientras que, la celulosa cristalina como las fibras de algodon es atacada de manera lenta por esta enzima (Hernandez et al., 1999:4).
