Abstract

Five yeast morphotypes were isolated from biogas reactors at North Wyke Research, Okehampton, UK. Out of the five morphotypes, four were identified as known species. In contrast, the fifth morphotype strain, Bio10(T), was found to differ from Bullera dendrophila and Kwoniella mangroviensis, its closest phylogenetic neighbours, by 2.6-2.9% with respect to the nucleotide sequence of the D1/D2 domain of the 26S rRNA gene and by 5.6-6.2% with respect to the internal transcribed spacer 1 (ITS1)-5.8S rRNA gene-ITS2 region. Bio10(T) also differs from these two species by a number of phenotypic characteristics. Thus, based on the phenotypic differences and phylogenetic analysis, strain Bio10(T) is assigned the status of a new species of Cryptococcus, for which the name Cryptococcus shivajii sp. nov. is proposed. The type strain is Bio10(T) (NCYC 3541(T) = CBS 11374(T)).
