alpha-Mannosidase and mannanase of some wood-rotting fungi.

Cultivation media from 11 wood-rotting fungi contained alpha-mannosidase and mannanase activity, alpha-Mannosidase was studied in more detail in Phellinus abietis and mannanase was studied more intimately in basidiomycetes Phellinus abietis, Trametes sanguinea and Pholiota aurivella. Suitable cultivation conditions and optimum conditions for the production of alpha-mannosidase and mannanase were determined. Both enzymes are constitutive; mannanase is extracellular, alpha-mannosidase was found in both mycelium and cultivation medium.
