Abstract
A total of 106 Penicillium species were tested to examine their ability of degrading cellobiose, pectin and xylan. The activity of β-glucosidase was generally strong in all the Penicillium species tested. P. citrinum, P. charlesii, P. manginii and P. aurantiacum showed the higher ability of producing β-glucosidasc than other tested species. Peetinase activity was detected in 24 Penicillium species. P. paracanescens, P. sizovae, P. sartoryi, P. chrysogenum, and P. claviforme showed strong pectinase activity. In xylanase assay, 84 Penicillium species showed activity. Strong xylanase activity was detected from P. megasporum, P. sartoryi, P. chrysogenum, P. glandicola, P. discolor, and P. coprophilum. Overall, most of the Penicillium species tested showed strong β-glucosidasc activity. The degree of pectinase and xylanase activity varied depending on Penicillium species.
