Resumo: The main fungal species present in self-heated chip piles of eucalypt wood in Brazil were Aspergillusfumigatus, Chrysosporium thermophilum, Dactylomyces thermophilus, Penicillium bacillisporum, Rhizomucorpusillus 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.

Este estudo determinou o crescimento micelial e a germinação de esporos em uma faixa de temperaturas que variou de 20 °C a 70 °C. Temperaturas ótimas foram observadas a 30 °C para A. fumigatus e P. bacillisporum; 40 °C para R. pusillus e 50 °C para C. thermophilum, D. thermophilus e T. aurantiacus. Não houve crescimento nas temperaturas de 60 °C e 70 °C. A incubação dos esporos em ágaráguaa 20 °C, 30 °C, 40 °C e 50 °C mostrou que somente A. fumigatus, P. bacillisporum e R. pusillus germinaram a 20 °C.Embrapa Florestas2010-06-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/140Pesquisa Florestal Brasileira; n. 54 (2007): jan./jun.
