Technical Abstract: The chapter describes the asexual ascomycete yeast genus Trigonopsis and is to be published in “The Yeasts, A Taxonomic Study, 5th edition.” The genus Trigonopsis has four known species and T. variabilis is famous for producing triangular cells, whereas the other described species do not. Multigene phylogenetic analysis places the genus near the base of the Saccharomycetales, the ascomcetous yeasts. T. variabilis is widely studied because it produces D-amino acid oxidases, enzymes that are valuable to the pharmaceutical industry because they catalyze intermediates for production of various drugs. In nature, the species are associated almost exclusively with grapes and may represent occcasional wine and beer spoilage organisms.
