摘　　要：益生菌存在于人体的肠道内,对调节肠道菌群具有重要作用。研究以可口革囊星虫蛋白肽为原料,研究可口革囊星虫蛋白肽对植物乳杆菌、嗜热链球菌、酪丁酸梭菌和青春双歧杆菌的影响,并且探究可口革囊星虫蛋白肽对植物乳杆菌、嗜热链球菌、青春双歧杆菌和酪丁酸梭菌在模拟胃肠液中的耐受性。结果表明:可口革囊星虫蛋白肽能够增加酪丁酸梭菌和青春双歧杆菌菌落数量,并且能够增强青春双歧杆菌在模拟胃液的耐受性。研究为可口革囊星虫蛋白肽在功能性食品中的应用提供了理论支持。Probiotics are known as the guardians of the intestinal tract.It plays a beneficial role in improving gastrointestinal tract health.The peptide of Phascolosoma esculenta was used as raw material,and the effect of the peptide of Phascolosoma esculenta on the growth of Lactobacillus plantarum,Streptococcus thermophilus,Clostridium tyrobutyricum,and Bifidobacterium adolescentis was evaluated in this research.Additionally,the tolerance of these four probiotics in the simulated gastrointestinal fluid was investigated.The results showed that the peptide of Phascolosoma esculenta could increase the population of Clostridium tyrobutyricum,and Bifidobacterium adolescentis.The peptide of Phascolosoma esculenta could inhibit the decrease in the population of Bifidobacterium adolescentis in the fluid environment of the stomach in vitro.This study could provide theoretical bases for developing marine peptides as functional foods in the food industry.
