Characterization of endo-beta-1,4-glucanase from a novel strain of Penicillium pinophilum KMJ601.

A novel endo-beta-1,4-glucanase (EG)-producing strain was isolated and identified as Penicillium pinophilum KMJ601 based on its morphology and internal transcribed spacer (ITS) rDNA gene sequence. When rice straw and corn steep powder were used as carbon and nitrogen sources, respectively, the maximal EG activity of 5.0 U mg protein(-1), one of the highest levels among EG-producing microorganisms, was observed.

Purification and characterization of a beta-1,4-glucosidase from a newly isolated strain of Fomitopsis pinicola.

An efficient beta-1,4-glucosidase (BGL) producing strain, Fomitopsis pinicola KMJ812, was isolated and identified based on morphological features and sequence analysis of internal transcribed spacer rDNA. An extracellular BGL was purified to homogeneity by sequential chromatography of F. pinicola culture supernatants on a DEAE-sepharose column, a gel filtration column, and then on a Mono Q column with fast protein liquid chromatography.
