The aim of this study was to evaluate a self-heating pasteurization technique in preparing substrates for mushroom production. Seven species were used: Agrocybe aegerita, Auricularia fuscosuccinea, Pleurotus djamor, P. eryngii, P. ostreatus, Lentinula edodes, and Ganoderma lucidum. They were cultivated on grass, corncob, wood shavings, and a mixture thereof. The self-heating technique allowed for pasteurization of 3 of the substrates (grass, corncob, and the mixture). The preheating chamber comprised a drawer placed under the pasteurization crate. With this chamber, it was possible to increase inlet air temperatures by 4−5°C. The evaluated mushroom species responded in different ways to the pasteurization process. P. ostreatus (control) and P. djamor produced basidiomes when cultivated in all pasteurization substrates. A. aegerita and P. eryngii fruited only on corncob and the mixture, whereas A. fuscosuccinea fruited only on the pasteurized corncob. G. lucidum and L. edodes did not fructify on the pasteurized substrates. Inglés
