We describe Candida aquaetextoris, a new yeast species isolated from sludge that accumulates at the main wastewater treatment facility which processes discharges from textile factories located in the Prato metropolitan district, northern Tuscany, Italy. This yeast degrades 4-(1-nonyl)phenol, a toxic intermediate originating from the microbial attack of nonylphenol polyethoxylates, which are nonionic surfactants largely used in leather and textile industries. In the investigation we employed conventional and molecular taxonomy techniques to compare the new isolate to strains of physiologically similar species, such as Candida maltosa and Candida tropicalis, as well as strains of quite phenotypically different species, such as Candida haemulonii. The results demonstrate that the yeast which we identified represents a separate taxon. The type strain of C. aquaetextoris is strain Lmar1, which has been deposited in the Industrial Yeast Collection of the Division of Applied Microbiology, Department of Plant Biology, University of Perugia, Perugia, Italy, as strain DBVPG 6732.
我们描述了水生念珠菌，这是一种从污泥中分离出的新酵母物种，该污泥积聚在意大利托斯卡纳大区北部普拉托市主要污水处理设施中，该设施处理来自当地纺织厂的废水排放。这种酵母可降解4-（1-壬基）苯酚，这是一种有毒中间体，由壬基酚聚乙氧基化物的微生物攻击产生，壬基酚聚乙氧基化物是皮革和纺织工业中广泛使用的非离子表面活性剂。在调查中，我们采用传统和分子分类技术，将新分离菌株与生理相似物种的菌株（如实玛利念珠菌和热带念珠菌）以及表型差异较大的物种的菌株（如哈氏念珠菌）进行比较。结果表明，我们鉴定出的酵母代表一个独立的分类单元。水生念珠菌的模式菌株是Lmar1菌株，已作为DBVPG 6732菌株保藏于意大利佩鲁贾大学植物生物学系应用微生物学部门的工业酵母保藏中心。
