摘 要：
采用液相-四级杆飞行时间质谱的方法结合Metlin数据库检索分析14株芽胞杆菌菌株发酵液的胞外成分。筛选出一株产鸭嘴花酚碱的芽胞杆菌菌株为甲基营养型芽胞杆菌Bacillus methylotrophicus FJAT-16022,其中该成分含量占其发酵液总代谢物含量的1.39%,匹配得分为95.1。表明甲基营养型芽胞杆菌芽胞杆菌Bacillus methylotrophicus FJAT-16022为鸭嘴花酚碱高产菌株,该研究为芽胞杆菌来源鸭嘴花酚碱活性物质的开发与利用提供理论依据。

摘 要：
A vasicinol-producing strain of Bacillus methylotrophicus FJAT-16022 was screened from 14 Bacillus-like bacteria with an aid of liquid chromatography-quadrupole time-of-flight mass spectrometry(LC-QTOF MS)combined with retrieval comparison against the mass spectrometry database,Metlin.The obtained vasicinol had a matching score of 95.1with the database,and its relative content was up to 1.73% of the total metabolites in the cultural supernatants.It appeared that B.methylotrophicus FJAT-16022 was a high-yield strain in producing vasicinol.The result obtained paved the way for the development and utilization of vasicinol from the identified bacterium.
