Abstract Quantitative differentiation of microbial activity in wheat straw substrate is described after different heat pre-treatments and addition of water during solid-state fermentation. All the 28 tested strains of tropical and sub-tropical edible mushrooms colonized sterile wheat straw. Substrate pre-treated at 25°C was primarily colonized by Coprinus sp. and other competitive microorganisms, and had the highest pH values. With some exceptions, increasing rates of growth occurred with substrate pre-treatment at 60 and 90°C. Best growth and highest speed of colonization were on sterilized straw. Heat pre-treatment of cereal straw at 60 and 90°C should be sufficient for commercial cultivation processes. Thus, a short fermentative pre-treatment could reduce the risk of infection. The strains tested do not differ significantly from those of temperate climates.
