摘要: 选取10种芽胞杆菌模式菌株, 分别进行不同重复检测次数的脂肪酸鉴定。从脂肪酸鉴定结果、相似指数SI、脂肪酸含量和聚类分析4个角度研究了芽胞杆菌属种类脂肪酸鉴定的可靠性。通过脂肪酸鉴定, 10种芽胞杆菌可以准确地鉴定到种。鉴定指数SI与脂肪酸含量具有相关性, 与重复检测次数无关, 可得出脂肪酸鉴定指数重复性较好。芽胞杆菌属种类的脂肪酸组成和含量基本无变化或者变化很小, 聚类分析发现重复检测次数对芽胞杆菌的种分类地位无影响。研究结果表明芽胞杆菌脂肪酸鉴定具有较好的可靠性。

Abstract: In this study, 10 type Bacillus species were selected and carried out a different repeats of fatty acid respectively using Sherlock MIS system. From the identitication results, similarity index(SI), fatty acid content and clustering analysis, it was showed that all species were accurately identified as species level, SI had a good reproducibility, the fatty acid content was little changed in each pepetition, and was no effection on the taxonomic status of Bacillus species by clustering analysis. Finally, the results were determined that the Bacillus fatty acid identification had a good reliability.
