Some observations on the penetration sequences, effect of pH and humus formation by wood microfungi

  • R. F. Sharp


The colonisation patterns and penetration sequences of microfungi in model beechwoods were described. Monocultures were inoculated onto cellulose agar and beechwood altered to a particular pH and cellulolysis and strength measurements taken. The formation of humic-acid was demonstrated for some species.
