Abstract

We analyzed the adhesion capacity to mucus of 31 Lactobacillus pentosus strains isolated from naturally fermented Aloreña green table olives using an immobilized mucin model. On the basis of their adhesive capacity to mucin, three phenotypes were selected for cell-wall protein proteomic analysis to pinpoint proteins involved in the adhesion process: the highly adhesive L. pentosus CF1-43 N (73.49% of adhesion ability), the moderately adhesive L. pentosus CF1-37 N (49.56% of adhesion ability) and the poorly adhesive L. pentosus CF2-20P (32.79% of adhesion ability). The results revealed four moonlighting proteins over-produced in the highly adhesive L. pentosus CF1-43 N, which were under/not produced in the other two L. pentosus strains (CF1-37 N and CF2-20P). These proteins were involved in glycolytic pathway (phosphoglycerate mutase and glucosamine-6-phosphate deaminase), stress response (small heat shock protein) and transcription (transcription elongation factor GreA). Furthermore, the relative fold change in gene expression analysis showed significant up-regulation of the genes coding for these four moonlighting proteins in the highly adhesive L. pentosus CF1-43 N versus the poorly adhesive L. pentosus CF2-20P and also in response to mucin for 20 h which clearly indicate the significant role of these genes in the adhesion capacity of L. pentosus. Thus, these proteins could be used as biomarkers for mucus adhesion in L. pentosus. On the other hand, mucin exposure induced other probiotic effects in L. pentosus strains, enhancing their co-aggregation ability with pathogens and possible inactivation.

  • Adhesion is a specific interaction between bacterial surface components and complementary host cell surface structures, and is a crucial prerequisite step for bacterial colonization in the digestive tract.

    “Adhesion is a specific interaction between the bacterial surface components and the complementary structure of the host cell surface, which is a crucial and prerequisite step for bacterial colonization in the digestive tract (Buck et al., 2005; Bagon et al., 2018; Montoro et al., 2018).”

    From Adhesion and Colonization of the Probiotic Lactobacillus plantarum HC-2 in the Intestine of Litopenaeus Vannamei Are Associated With Bacterial Surface Proteins (2022) · cites this paper as Montoro et al., 2018

    The Introduction says adhesion to intestinal epithelium is important for successful colonization, and the Discussion links bacterial surface proteins and other components to interaction with mucin. The Discussion calls adhesion a presumed requisite and says it could help colonization; it does not establish the claimed specific interaction with complementary host-cell surface structures or an unqualified prerequisite.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
