摘　　要：为改善梗丝品质,利用从醇化烤烟烟叶表面分离得到的微生物菌株V35(Bacillus pumilus Van35)制成菌剂用于梗丝处理。30℃处理48 h后,测定了梗丝的常规化学成分、细胞壁物质含量和致香成分,并对梗丝进行感官质量评价。结果表明,V35菌剂处理后,梗丝的总糖和还原糖均较对照有所上升,总氮含量下降,纤维素和果胶含量较对照降低,总挥发性香气物质总量较对照有所上升。感官评吸结果表明,V35菌剂能降低梗丝杂气和刺激性,提升梗丝香气量。Microbial preparation of V35, a Bacillus pumilus strain isolated from tobacco leaf surface, was sprayed on tobacco cut stem. Chemical components, cell wall matters, aroma components and smoking quality of cut stem were determined after 48 hours treatment at 30℃ . Results showed that total sugar, reducing sugar and total aroma components increased, while total nitrogen, cellulose and pectin decreased. Sensory evaluation showed that microbial preparation treatment can reduce offensive irritancy while increase aroma quantity in tobacco cut stem.
