Influence of gastrointestinal system conditions on adhesion of exopolysaccharide-producing Lactobacillus delbrueckii subsp. bulgaricus strains to caco-2 cells

Abstract

This study aimed to assess the transit tolerance of potential probiotic dairy

Probiotic Potential of Yeasts Isolated From Traditional Indian Fermented Foods

“…Another physiological benefit is that EPS is retained longer in the gastrointestinal tract, so that colonization by the probiotic microorganisms can be enhanced [67]. Consequently, EPS producing probiotic cultures can contribute human health by positively affecting the gut microflora [68]. S. cerevisiae strains, isolated traditional fermented food products, producing exopolysaccharides have been previously reported [43].…”

In vitro gastrointestinal resistance of Lactobacillus acidophilus La-5 and Bifidobacterium animalis Bb-12 in soy and/or milk-based synbiotic apple ice creams

“…Previous studies have reported the effect of the pH in the morphology and viability of different Lactobacillus strains (Hossein Nezhad et al, 2010;Norton et al, 1993;Sanhueza et al, 2015). Moreover, the presence of proteases such as pepsin and trypsin have also been reported to influence not only the viability of different strains of lactobacilli, but also their ability to adherence (Darilmaz et al, 2011).…”

Lactobacillus strains belonging to Casei group display various adherence to enterocytes and mucus

“…Adhesins responsible for binding to molecules present on the surface of enterocytes are, for example, collagen binding protein CbsA or fi ronectin binding protein FbpA (Antikainen et al, 2002;Buck et al, 2005). Adhesion to intestinal mucus occurs with the participation of adhesins such as mucin binding proteins (Roos and Jonsson, 2002), or certain polysaccharides associated with the bacterial cell wall or secreted into the external environment (Darilmazl et al, 2011). SpaCBA protein complex forming fi mbriae on the surface of bacterial cells is responsible for the adhesion to both mucus and enterocytes (Kankainen et al, 2009;Reunanen et al, 2012).…”
