Abstract

The main fungal species present in self-heated chip piles of eucalypt wood in Brazil were Aspergillus
fumigatus, Chrysosporium thermophilum, Dactylomyces thermophilus, Penicillium bacillisporum, Rhizomucor
pusillus and Thermoascus aurantiacus. This study determined the micelial growth and spore germination of these species at several temperatures on PDA medium ranging from 20 °C to 70 °C. Optimum growth temperatures were observed at 30 °C for A. fumigatus and P. bacillisporum; 40 °C for R. pusillus and 50 °C for D. thermophilus, C. thermophilum and T. aurantiacus. Growth was not observed at 60 °C and 70 °C. Incubation of spores on wateragar medium at 20 °C, 30 °C, 40 °C and 50 °C showed that only A. fumigatus, P. bacillisporum and R. pusillus could germinate at 20 °C.
