Abstract
An unknown yeast species was isolated from maize silage and was determined to be novel on the basis of morphological and physiological characteristics, nucleotide sequence of domain D1/D2 of LSU rDNA and from its electrophoretic karyotype. The name for the proposed new species is Saccharomyces bulderi Middelhoven, Kurtzman et Vaughan-Martini (type strain CBS 8638, NRRL Y-27203, DBVPG 7127). S. bulderi is closely related to S. barnettii and S. exiguus from which it can be distinguished by having a double vitamin requirement of biotin and thiamine and by no or slow aerobic growth on raffinose, a sugar that on the contrary is fermented rapidly. Gluconolactone is rapidly fermented with ethanol, glycerol and carbon dioxide being the main products.
