FIG. 4.

Enzyme degradability of BC and MBC mats. (a) After addition of cellulase, the amount of glucose liberated was measured at different times. The black dotted arrow shows the difference in hydrolysis rates between BC and MBC. (b) LC-MS profile of MBC hydrolyzed with Tricoderma reesei cellulase. (c) LC-MS profile of MBC treated with chicken egg white lysozyme. A mixture of oligomers of up to 950-Da mass was obtained. (d) MBC was hydrolyzed with Tricoderma reesei cellulase, and the remaining undigested portion was treated with chicken egg white lysozyme. The LC-MS profile of lysozyme-treated undigested polymer is shown.
