Cryptococcus cerealis sp nov a psychrophilic yeast species isolated from fermented cereals

Passoth, Volkmar; Andersson, Ann-Christin; Olstorpe, Matilda; Theelen, Bart; Boekhout, Teun; Schnurer, Johan


Two yeast strains isolated in 2007 from fermented pig feed were studied, including the analysis of sequences of the D1/D2 and ITS-regions of the rDNA-repeats, their morphology and nutritional physiology. Sequence comparison of the D1/D2 and ITS regions demonstrated that the strains do not belong to any known species. Therefore, a new species, Cryptococcus cerealis with the type strain CBS 10505, is proposed. The species belongs to Filobasidiales (Agaricomycetes, Basidiomycota), and has Cryptococcus saitoi as the closest related species. The new species is psychrophilic, showing significant growth at 4 and 10A degrees C.
