Characterization and biobleaching effect of hemicellulases produced by thermophilic fungi

摘要

Various thermophilic fungi were isolated and screened for the presence of hemicellulases and cellulases. Strain MED 4B1 was identified as Thermomyces lanuginosus. The grwoth-associated production of xylanases, #beta# -xylosidases and carboxymethylcellulases (CMCases) from MED 2D and T. lanuginosus MED 4B1 was monitored. Analysis of the culture supernatant revealed high levels of xylanase activity, with low inducible levels of #beta# -xylosidase activity.
