[Investigations into the biological disintegration of organic natural substances by aquatic hyphomycetes (author's transl)].

The ability of 5 aquatic Hyphomycetes to produce Amylase, Pectinase and Cellulase was investigated. All the tested strains were weak producers of Amylase and good producers of Pectinase, whereas degradation of Cellulose was only found with two strains.
