ABSTRACT
Wood was more effectively degraded in dual cultures of Pycnoporus coccineus with Flammulina velutipes, Pleurotus ostreatus, or Polyporus arcularius than in their single cultures based on weight losses of chopsticks. The similar effects were attained in dual cultures of the selected Basidiomycetes and various soil fungi. Cellulose-degrading fungi were evaluated for their abilities in Difco potato dextrose broth or Difco malt extract broth cultures with cellulose substrates in plastic Petri dishes. As cellulose substrates, filter papers, absorbent cotton, and processed cellulose powder were tested and the results were presented partially. The assay was conducted by comparing the dry weights between the uninoculated control culture weights with those of the cultures inoculated with test fungi after 30-day incubation. The dry weights were obtained in drying the cultures at 50 degree celsius for at least two days. Soil fungi were tested using at least 25 isolates.
