Abstract

A new species of Pichia and two new species of Candida are described and were determined to be genetically isolated from all other currently recognized ascomycetous yeasts from their sequence divergence in the species-variable D1/D2 domain of large subunit (26S) ribosomal DNA. The three species were primarily isolated from the frass of wood-boring insects living in pine and spruce trees. The new species and their type strains are the following: Pichia ramenticola NRRL YB-1985 (CBS 8699), mating type alpha (NRRL YB-3835, CBS 8700, mating type a), Candida piceae NRRL YB-2107 (CBS 8701), and Candida wyomingensis NRRL YB-2152 (CBS 8703). Pichia ramenticola and C. piceae assimilate methanol as a carbon source; P. ramenticola is the first known heterothallic ascomycetous yeast to utilize this compound.

摘要

描述了一种新的毕赤酵母属物种和两种新的念珠菌属物种，根据它们在大亚基（26S）核糖体DNA物种可变的D1/D2结构域中的序列差异，确定它们与所有其他目前已知的子囊菌酵母在基因上是隔离的。这三个物种主要从生活在松树和云杉树中的蛀木昆虫的粪便中分离得到。新物种及其模式菌株如下：拉曼毕赤酵母NRRL YB - 1985（CBS 8699），交配型α（NRRL YB - 3835，CBS 8700，交配型a），云杉念珠菌NRRL YB - 2107（CBS 8701），以及怀俄明念珠菌NRRL YB - 2152（CBS 8703）。拉曼毕赤酵母和云杉念珠菌以甲醇作为碳源；拉曼毕赤酵母是已知的第一种利用该化合物的异宗配合子囊菌酵母。
