Abstract
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.
