Interpretive Summary: In this study, six new species of the yeast genus Blastobotrys are described. The species were recognized as new from gene sequence comparisons using a gene sequence database developed at NCAUR. Species of Blastobotrys grow on a variety of biochemicals not utilized by other yeasts, and their unusual metabolism has attracted the interest of biotechnologists who might use them for industrial processes or bioremediation of chemical wastes.

Technical Abstract: The genus Blastobotrys, which now includes species previously assigned to the synonymous genera Arxula and Sympodiomyces, represents the anamorph of the ascosporogenous genus Trichomonascus. Six new species are proposed for assignment to Blastobotrys and were detected from their unique nucleotide sequences in large-subunit rDNA, ITS1-5.8S-ITS2 rDNA, mitochondrial small-subunit rDNA and the cytochrome oxidase II gene. The proposed new species are the following: Blastobotrys americana sp. nov. (type strain NRRL Y-6844T, CBS 10337T, substrate unknown, Kansas, USA), Blastobotrys illinoisensis sp. nov. (type strain NRRL YB-1343T, CBS 10339T, from forest debris, Illinois, USA), Blastobotrys malaysiaensis sp. nov. (type strain NRRL Y-6417T, CBS 10336T, from soil, Malaysia), Blastobotrys muscicola sp. nov. (type strain NRRL Y-7993T, CBS 10338T, from moss, Louisiana, USA), Blastobotrys peoriaensis sp. nov. (type strain NRRL YB-2290T, CBS 10340T, from a fungus, Peoria, Illinois, USA), and Blastobotrys raffinofermentans sp. nov. (type strain NRRL Y-27150T, CBS 6800T, substrate unknown).
