Abstract

In this study, 99 strains of species were isolated from various samples collected from different locations in China, among which 14 isolates showed different morphological characteristics to other strains identified as known species. Based on morphological characteristics, those 14 strains were classified into four groups, represented by stains of KCL139, MDSC-10, XZY411-4, and MQL9-100, respectively. Molecular analysis of the internal transcriptional spacer (ITS) and part of the large ribosome subunit (D1/D2 domains) indicated that those four groups represent four new species in the . Therefore, the names sp. nov., sp. nov., sp. nov., and sp. nov. are proposed for KCL139, MDSC-10, XZY411-4, and MQL9-100, respectively. We also found that there were differences in the yield of exopolysaccharides (EPS) among and within species, indicating strain-related exopolysaccharide-producing diversity.

摘要

在本研究中，从中国不同地点采集的各种样本中分离出了99株该物种的菌株，其中14株分离株与其他鉴定为已知该物种的菌株表现出不同的形态特征。基于形态特征，这14株菌株被分为四组，分别以KCL139、MDSC - 10、XZY411 - 4和MQL9 - 100菌株为代表。对内部转录间隔区（ITS）和大核糖体亚基的一部分（D1/D2结构域）的分子分析表明，这四组代表了该属中的四个新物种。因此，分别为KCL139、MDSC - 10、XZY411 - 4和MQL9 - 100提出了新物种名称[具体物种名称] sp. nov.、[具体物种名称] sp. nov.、[具体物种名称] sp. nov.和[具体物种名称] sp. nov.。我们还发现，不同物种之间以及物种内部的胞外多糖（EPS）产量存在差异，表明与菌株相关的胞外多糖产生多样性。
