Heat resistant fungi isolated from soil

Abstract The Thermal death time values (TDT) were estimated for Dichotomomyces cejpii, Gilmaniella humicola, Talaromyces avellaneus and Talaromyces bacillisporus isolated from soil. TDT values were compared with the TDT values of the known heat-resistant species, Byssochlamys nivea, Neosartorya fischeri and Talaromyces flavus . All species studied showed considerable heat resistance. The most resistant species Talaromyces avellaneus (172 cfu, initial concentration) of the isolates with unknown heat resistance withstood 90°C for 10 min. Byssochlamys nivea appeared to be the most sensitive species under our experimental conditions.
