Karl-Erik Eriksson (42) reported that he had prepared an enzyme from Chrysosporium lignorum which, when combined with each of three CM-cellulase enzymes, increased the hydrolysis rate of cotton tenfold. When he incubated this enzyme, which he believed to be of the Ci type, with cellohexaose and observed cellobiose as the only product, he concluded that it was an exo-glucanase which split off cellobiose units. Later (27) Eriksson and Rzedowski reported that the three CM-cellulase enzymes from C. lignorum contained 13, 10, and 7% carbohydrate and catalyzed the hydrolysis of cotton and cellodextrins to produce cellobiose and glucose in the approximate ratio of 3 1.

The cellulase activities in Cellvibrio fulvus, Chaetomium thermophile, Sporotrichum thermophile and Thermoascus aurantiacus have been examined. The development of cellulolytic enzymes in cultures of Chrysosporium lignorum during growth has been monitored. ... 

The action of an exo-l,4-j8-D-glucanase from Sporotrichum pulverulentum Chrysosporium lignorum) on celluloses showed a synergistic effect in the presence of e i/o-l,4- -D-glucanases. Products released by the eji u-l,4-j8-D-glucanase have the a-configuration. 

An increase in production of laccase and MnP by T. trogii was observed by the addition of easily available carbon and nitrogen sources to the culture medium, such as malt-extract and peptone [90], This is due to the presence of aromatic amino acids tryptophan and tyrosine in the Malt-extract broth. Same observation in Phlebia radiate and Phlebia fascicularia with laccase and MnP activity in T. versicolor of about 2.40 and 2.00 U/mL, respectively was observed [5]. A large increase in LiP production when adding tryptophan to the cultures of T. versicolor, P. chrysosporium and Chrysosporium lignorum was observed [23].
