An ustilaginomycetous anamorphic yeast, isolated from orange leaves on Jeju island in South Korea, represents a novel Pseudozyma species according to morphologic and physiologic findings and molecular taxonomic analysis using the D1/D2 domains of the large subunit (26S) rRNA gene and the internally transcribed spacer (ITS) 1+2 regions. The name Pseudozyma jejuensis sp. nov. is proposed for this novel species, with OL71(T) (=KCTC 17482(T)=CBS 10454(T)) as type strain. In the present study, we have also demonstrated that Pseudozyma jejuensis OL71 is capable of producing cutinase and degrading polycaprolactone. These results suggest that Pseudozyma jejuensis or its cutinase may be useful for the biological degradation of plastic waste.
从韩国济州岛的橙叶中分离出的一种黑粉菌纲无性型酵母,根据形态学、生理学研究结果以及利用大亚基(26S)rRNA基因的D1/D2结构域和内转录间隔区(ITS)1+2区域进行的分子分类分析,它代表了一个新的假丝酵母属物种。为此新物种提议命名为济州假丝酵母(Pseudozyma jejuensis),以OL71(T)(=KCTC 17482(T)=CBS 10454(T))作为模式菌株。在本研究中,我们还证明了济州假丝酵母OL71能够产生角质酶并降解聚己内酯。这些结果表明,济州假丝酵母或其角质酶可能对塑料垃圾的生物降解有用。
