摘要

The ability of two wood-decay basidiomycetes to produce extracellular mucilaginous material (ECMM) and its relationship with total biomass production has been investigated. Growth and ECMM production by the white-rot fungus Coriolus versicolor and the brown-rot fungus Gloeophyllum trabeum were assessed in liquid culture under different nutritional and environmental conditions. Nutritional, pH and temperature factors all influenced significantly the proportion of ECMM in the total biomass produced. When total biomass production was reduced due to unfavorable growth conditions (stress), the proportion of ECMM in the biomass was elevated. The results are discussed with regard to the possible role(s) of ECMM in the responses of these fungi to stress.
