摘要:

旨在建立一种快速测定枯草芽孢杆菌Czk1挥发性物质的方法。以总峰个数和总峰面积为指标,采用顶空固相微萃取气相色谱质谱联用技术鉴定枯草芽孢杆菌Czk1的挥发性物质,采用单因素和正交试验确定最佳萃取条件,并在此条件下对Czk1的挥发性物质组分进行分析。最佳组合为50/30 μm DVB/CAR/PDMS萃取头、萃取温度40℃,萃取时间40 min,解吸时间7 min,升温程序4。在此优化条件下,共获得33种挥发性物质,其主要组分含有酮类(28.65%)、酚类(13.51%)、酯类(9.17%)、醛类(15.60%)、醇类(12.08%)、碳氢化合物(4.49%)、其他类物质(10.58%)。该萃取方法的建立可为枯草芽孢杆菌Czk1挥发性物质的分析提供参考。

Abstract:

The aim is to establish a rapid method for determining volatile organic compounds of Bacillus subtilis Czk1. The volatile organic compounds of Bacillus Subtilis Czk1 were identified by using headspace solid phase microextraction gas chromatogram mass spectrometry with the total peak number and total peak area as indicators, and the optimal extraction conditions were determined by single factor and orthogonal test. In the end, the volatile organic compounds of Czk1 were analyzed under these conditions. The results showed that the optimum extraction condition was the SPME fibers of 50/30 μm DVB/CAR/PDMS, extraction temperature of 40°C, extraction time of 40 min, desorption time of 7 min, and temperature program condition of 4. 33 kinds of volatile organic compounds were gained under the optimized condition, and the main components included ketones (28.65%), phenols (13.51%), esters (9.17%), aldehydes (15.60%), alcohols (12.08%), hydrocarbons (4.49%), and other substances (10.58%). The extraction method can provide a reference for the analysis of volatile organic compounds in Bacillus subtilis Czk1.
