Production of D-xylanases by thermophilic fungi using different methods of culture

  • W. Grajek

Summary

Seven thermophilic strains of fungi were examined for their ability to produce D-xylanase in Liquid and solid-state fermentations. It was confirmed that the best producers of xylanase, among microorganisms used, wereH. Lanuginosa andS. thermophile in liquid fermentation, andT. aurantiacus andH. lanuginosa in solid-state fermentations. The higher productivity of xylanase, namely 18,72 IU/ml, was obtained in liquid culture ofH. lanuginosa. The pH and temperature optima of enzymes from liquid and solid-state cultures of fungi used were also presented.
