Composition and difference of volatile components in fermentation metabolites of Lachnum YM406 with dif-ferent carbon sources and growth factors was analyzed by GC-MS.The results showed that the metabolites are various with different carbon sources and growth factors , mainly including organic acids , amines, alkanes, esters, alcohols, pyrroles and other substances .There were respectively 7, 7, 10 kinds of volatile metabolites in fermentation broth with 20 g/L of glucose, sucrose, and starch as carbon source .Meanwhile, in fermentation broth added with 1mg/L VC, VB1, glycine, tryptophan as growth factors , there were 6, 7, 7, 12 kinds of volatile metabolites respectively .These results showed that the fermentation metabolites by Lachnum YM406 under different culture conditions were fairly di-verse, suggested that strain YM406 had important application value .%采用GC-MS法对一种粒毛盘菌(Lachnum sp.)在不同碳源、生长因子条件下发酵代谢产物的挥发性成分组成与差异进行分析.结果显示,不同碳源和生长因子条件下产生的代谢产物不同,主要包括有机酸、胺类、烷烃类、酯类、醇类、吡咯等物质.分别以20 g/L的葡萄糖、蔗糖、淀粉为碳源的发酵液中检测到的挥发性代谢产物为7、7、10种;添加1 mg/L的VC、VB1、甘氨酸、色氨酸作为不同生长因子的发酵液中检测到的挥发性代谢产物分别为6、7、7、12种.结果显示粒毛盘菌YM406发酵代谢产物具有丰富的多样性,并且在不同的培养条件下产生的代谢产物存在一定的差异.
