Degradation of Fungal and Actinomycete Mycelia by Free

Abstract

Summary: Commercial wheat straw/horse manure compost used for production of the cultivated mushroom contains a fungal and actinomycete microbial biomass of some 1.5% before inoculation with . It has been shown that these mycelia can be used by as a sole source of carbon, nitrogen and phosphorus. Mycelium of the thermophilic fungus var. , a major component of compost microbial biomass, was digested over a 28 d period by growing in liquid culture, as determined by light and electron microscopy. Mycelial walls of var. contained (by wt) 30% glucose, 22% glucosamine, 6-8% galactose, 2-3% mannose and traces of other sugars. Enzymes that possibly degrade fungal and actinomycete cell walls were produced by during growth on such mycelia, and activities of other extracellular enzymes involved in the decomposition of cytoplasmic contents were determined.
