Abstract

Candida arabinofermentans (type strain NRRL YB-2248, CBS 8468), a new yeast that ferments the pentose L-arabinose, is described. The three known strains of this new species were isolated from insect frass of pine and larch trees in the U.S. Phylogenetic analysis of nucleotide sequences from the D1/D2 domain of large subunit (26S) ribosomal DNA places C. arabinofermentans among the methanol-assimilating yeasts and most closely related to Candida ovalis. Strains of the new species produce 0.7-1.9 g/l ethanol from L-arabinose.
