[Characterization of fungi isolated from woody-chip piles, especially thermophilic and thermotolerant isolates].
Samples were taken in order to isolate fungi from four woodychip piles (three of these were treated with liquid manure) from different depths. 39 species of 121 isolates could be determined. They represent 28 genera. Aspergillus fumigatus, Trichoderma reseei, Corynascus sespedonium and Mucor hiemalis were isolated most frequently. The isolates were examined for their temperature requirements. Following the definitions of Hawskworth (1983) they could be classified into the three groups of "thermophilic" (28 isolates), "thermotolerant" (29 isolates) and "mesophilic" (64 isolates) fungi. The temperature requirements for sporulation were also examined. Partly sporulation could be observed within more restricted temperature borders than growth but optimal sporulation occurs within wider temperature areas than optimal growth. The optimal sporulation-temperature was defined as the temperature at which sporulation began fastest.
