| 摘 要： | 以发酵液中苯乳酸含量作为标志物筛选能够抑制霉菌的植物乳杆菌,得到一株植物乳杆菌Lp45。将其与酸乳发酵剂同时发酵酸乳,验证其对酸乳的防腐作用和对酸乳的影响,结果显示植物乳杆菌Lp45作为生物保鲜菌种在接菌量为150 U/T时具有非常好的生物保鲜作用而且使酸乳在货架期内的活菌数保持在1.0×10~8cfu/mL以上,生产适应性优秀。

| Abstract: | The study was screened and obtained Lactobacillus Plantarum Lp45 which could inhibit mold,by a method of using phenyllactic acid in the fermentation broth as a marker.The results showed that Lactobacillus Plantarum Lp45,as a biological preservative strain,had a very good biological preservative effect when the inoculation amount was 150 U/T and the living bacteria count in the shelf life of yogurt was kept above 1.0×10~8 cfu/m L,suggesting that the strain had excellent production adaptability. |
