Yeast cell wall (YCW) preparations and yeast mannoprotein extracts have been effective against some enteropathogenic bacteria as Campylobacter jejuni, Escherichia coli, and Salmonella, and they can affect the population of beneficial lactic acid bacteria (LAB). In this work, we studied the effect of a mannoprotein extract on five strains of LAB. This extract was metabolised by the bacteria, enhancing their survival in simulated gastrointestinal juice, and increasing the adherence of Lactobacillus plantarum, L. salivarius, and Enterococcus faecium to Caco-2 cells. Yeast mannoproteins are promising naturally occurring compounds that could be used to enhance LAB intestinal populations and control pathogens.
酵母细胞壁（YCW）制剂和酵母甘露聚糖提取物已被证明对某些肠道致病菌有效，如空肠弯曲菌、大肠杆菌和沙门氏菌，并且它们可以影响有益乳酸菌（LAB）的种群。在这项工作中，我们研究了甘露聚糖提取物对五种 LAB 菌株的影响。该提取物被细菌代谢，增强了它们在模拟胃肠液中的生存能力，并增加了植物乳杆菌、唾液乳杆菌和粪肠球菌对 Caco-2 细胞的黏附。酵母甘露聚糖是一种很有前途的天然化合物，可用于增强 LAB 肠道种群并控制病原体。
