雪菊精油对希氏肠球菌产酪胺及相关基因表达的影响
TS207.7; 探讨不同质量浓度雪菊精油对希氏肠球菌(Enterococcus hirae)N47产酪胺的影响机制.利用反转录实时定量聚合酶链式反应分析E.hirae在雪菊精油作用下酪氨酸脱羧途径相关基因的表达情况;利用高效液相色谱法检测不同质量浓度雪菊精油对E.hirae产酪胺的影响.并将E.hirae接入到含不同质量浓度雪菊精油的熏马肠中发酵,评估香肠pH值、菌落总数和酪胺积累量.结果表明:在E.hirae纯培养体系和熏马肠体系中,雪菊精油通过抑制微生物的生长和酪氨酸脱羧途径中tyr DC、tyr P基因的表达,降低酪胺的积累量(P...
