摘要(Abstract)：

为探究产细菌素的乳酸菌在食品保鲜中的效果，该实验将产细菌素的乳酸菌戊糖片球菌SU-1(P.pentosaceus SU-1)接种于小型独立发酵菜模型中，测定理化性质，并通过高通量测序进行防腐功能研究；进一步将该菌的无细胞发酵上清液(CFS)应用于葡萄保鲜研究。结果表明，由高通量测序可知，接种发酵的物种丰富度降低，在接种P.pentosaceus SU-1的小型独立发酵抑菌模型中，沙雷氏菌属(Serratia)和Uncultured＿Enterobacteriaceae分别下降了98.98%和98.52%;进一步经过P.pentosaceus SU-1的CFS处理后，葡萄样品的腐烂率和失重率均显著降低。该研究中P.pentosaceus SU-1可以应用于食品防腐保鲜中，能够延长食品的保质期和安全期，增加社会价值和经济效益。
