The effect of the degree of crosslinking was examined under otherwise invariable conditions (pH 6, ionic strength I = 0.1, and 35°C). It was found that the lower the degree of crosslinking, the faster the enzymatic hydrolysis. Degradation of the three types of networks proceeded faster under the action of the enzyme complex from B. subtilis than by the enzymes from T. viride. © 2013 by Walter de Gruyter GmbH & Co.
