This assay is a good indicator of cellulolytic ability since endoglucanase is generally produced
in larger titres by fungi than cellobiohydrolase (Cai, Buswell and Chang, 1994;
Buswell et al., 1996; Pointing et al., 1999a), in addition many fungi that
successfully degrade cellulose in wood produce no detectable cellobiohydrolase
(Eaton and Hale, 1993)
