Specific enzymatic activity of Penicillium echinulatum strains in submerged cultures using different carbon sources at 96 h of cultivation. The graphs on the left correspond to the wild-type 2HH, and the graphs on the right correspond to the mutant strain S1M29. The hydrolytic potential of the broths of Penicillium echinulatum strains was tested on different substrates. a, b β-glucosidases. c, d endoglucanases. e, f xylanase, and g, h pectinase. pNPG p-nitrophenyl-β-d-glucopyranoside, pNPC p-nitrophenyl-β-d-cellobioside, pNPX p-nitrophenyl-β-d-xylopyranoside, pNPA p-nitrophenyl-α-d-arabinofuranoside, AVI Avicel®, LIC Lichenan, CMC carboxymethyl cellulose, ARAX rye arabinoxylan, XIL xylan, MAN mannan, PEC pectin, FEA feruloyl acetate, PST potato starch
