Abstract

Numerous strains of an unusual asexual yeast species were isolated from flowers of morning glory (Ipomoea spp., Convolvulaceae) and associated drosophilids and sap beetles of the genus Conotelus sampled in Hawaii and in Brazil. The nutritional profile of this yeast is similar to those of Metschnikowia hawaiiensis and Metschnikowia continentalis, which share the same habitats. The cells are large, hydrophobic, and tend to remain attached after budding, causing the colonies on agar media to have a convoluted appearance, reminiscent of popcorn. The sequences of the D1/D2 domain of large subunit rDNAs of strains from three different localities confirmed that a single species is involved, and that it is related to large-spored Metschnikowia species. The type strain is UWO(PS)91-672.1 (CBS 8466).

摘要

从夏威夷和巴西采集的旋花科（Convolvulaceae）番薯属（Ipomoea spp.）的花朵以及相关的果蝇和Conotelus属的露尾甲中分离出了许多不寻常的无性酵母菌株。这种酵母的营养特征与生活在相同栖息地的夏威夷梅奇酵母（Metschnikowia hawaiiensis）和大陆梅奇酵母（Metschnikowia continentalis）相似。细胞较大，具有疏水性，出芽后往往仍保持附着状态，导致琼脂培养基上的菌落呈现出盘绕状外观，类似爆米花。来自三个不同地点的菌株的大亚基rDNA的D1/D2结构域序列证实，涉及的是单一物种，并且它与大孢子梅奇酵母属物种相关。模式菌株为UWO(PS)91 - 672.1（CBS 8466）。
