摘要:

为优化植物乳植杆菌(Lactiplantibacillus plantarum)HCS03-001的冻干粉制备工艺,探究其抗幽门螺杆菌的功能效果,通过单因素试验、主因素分析和响应面试验优化植物乳植杆菌HCS03-001冻干粉的制备工艺,采用体外抑菌试验验证该益生菌的抗幽门螺杆菌功效。结果发现,优化后制备冻干粉的最佳工艺条件为:发酵温度37 ℃,发酵时间16 h,接种量5.2%,冻干时间44 h,在此条件下活菌数达到5.85×1011 CFU·g-1。体外抑菌试验结果表明植物乳植杆菌HCS03-001的发酵上清液和菌悬液均能有效抑制幽门螺杆菌的生长,抑制率达到69.55%~78.78%。研究结果表明植物乳植杆菌HCS03-001具备抗幽门螺杆菌的功能。

Abstract:

The aim of the study is to optimize the preparation technology of freeze-dried powder of Lactiplantibacillus plantarum HCS03-001 and explore its functional effect of anti-Helicobacter pylori. In this study, the preparation technology of freeze-dried powder of Lactiplantibacillus plantarum HCS03-001 was optimized by single factor test, principal factor analysis and response surface test, and then the anti-Helicobacter pylori effect of the probiotics was verified by bacteriostatic test in vitro. The results showed that the optimum conditions for preparing freeze-dried powder were fermentation temperature 37 ℃, fermentation time 16 h, inoculum 5.2% and freeze-drying time 44 h. Under these conditions, the number of live bacteria was 5.85 × 1011 CFU·g-1. These results of bacteriostatic test in vitro showed that the fermentation supernatant and bacterial suspension of Lactiplantibacillus plantarum HCS03-001 could effectively inhibit the growth of Helicobacter pylori, and the inhibition rate was 69.55%~78.78%, which showed that Lactiplantibacillus plantarum HCS03-001 have the function of anti-Helicobacter pylori.
