摘要
对新鲜西瓜内生菌进行分离纯化,共获得3株纯系微生物。通过筛选获得一株代谢产物香气优雅、甜润、生长迅速的菌株。利用GC-M S对其发酵产物进行分析,结果表明经该微生物代谢,种子液成分由苯、胺、酚等物质转化成了酸和醇等主要香气成分物质,苯含量从58.65%降到了1.35%,其次酸类物质和醇类物质分别占峰面积的55.06%和42.64%。利用该菌株发酵制备得到的发酵型烟用香料产品FM XG-A具有使烟香柔和、细腻、饱满的作用。
The fresh watermelon endophyte was separated and purified to obtain three strains of pure microbe which screened for a strain with elegant aroma,sweet,rapidly growing plant metabolism product.The fermentative product was analyzed by GC-MS,and the results showed that with the microbial metabolism,seeds liquid ingredients by benzene,amine,phenolic substances transformed into material main with aroma compositions such as alcohol and acid.The content of benzene fell from 58.65% to 1.35%,and acid material and alcohol material accounted for 55.06% and 42.64% of the peak area.The spices products FMXG-A of fermentation type for cigarette obtained by fermentation of strains had the effect of making cigarette sweet soft,delicate,smoking full.
