Purification and characterization of laccase from chaetomium thermophilium and its role in humification
Article Abstract:
Research was conducted to isolate a laccase-producing microorganism from composting municipal solid waste, purify and characterize the laccase and study the role it plays in the formation of humic substances. Laccase activity was exhibited by the cellulolytic fungi Chaetomium thermophilium when it was developed at 45 degrees C both in liquid and in solid media. A soluble polymer was formed when the hydrophobic acid fraction was added to a reaction assay mixture containing laguaiacol and laccase. Results show that laccase activity can be maintained for long periods at high temperatures.

Growth characteristics of the thermophilic fungus Scytalidium thermophilum in relation to production of mushroom compost
Article Abstract:
A model describing the growth of Scytalidium thermophilum in a mushroom compost was developed and presented. S. thermophilum is a thermophilic fungus essential to the production of mushoom compost. A model wasdeveloped which closely simulates the growth conditions for this fungus. Results based on this model show that compost production can be improved by useof a lower temperature for pasteurization. Such reduction can decrease compost production time by at least one day.

Growth-promoting effect of thermophilic fungi on the mycelium of the edible mushroom Agaricus bisporus
Article Abstract:
The thermophilic fungus Scytalidium thermophilum had a salutary effect on mycelial growth of Agaricus bisporus. The growth enhancement was apparently due to carbon dioxide production by S. thermophilum, rather than any intrinsic quality of this fungus. The higher growth rate was the effect of a higher rate of hyphal extension and does not seem to be related to the rate of biomass increase of the mycelium.
