Abstract

The ability to produce polysaccharides with diverse biological functions is widespread in bacteria. In lactic acid bacteria (LAB), production of polysaccharides has long been associated with the technological, functional and health-promoting benefits of these microorganisms. In particular, the capsular polysaccharides and exopolysaccharides have been implicated in modulation of the rheological properties of fermented products. For this reason, screening and selection of exocellular polysaccharide-producing LAB has been extensively carried out by academia and industry. To further exploit the ability of LAB to produce polysaccharides, an in-depth understanding of their biochemistry, genetics, biosynthetic pathways, regulation and structure-function relationships is mandatory. Here, we provide a critical overview of the latest advances in the field of glycosciences in LAB. Surprisingly, the understanding of the molecular processes involved in polysaccharide synthesis is lagging behind, and has not accompanied the increasing commercial value and application potential of these polymers. Seizing the natural diversity of polysaccharides for exciting new applications will require a concerted effort encompassing in-depth physiological characterization of LAB at the systems level. Combining high-throughput experimentation with computational approaches, biochemical and structural characterization of the polysaccharides and understanding of the structure-function-application relationships is essential to achieve this ambitious goal.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Genes of the Wzy-dependent pathway have been reported only in Weisella, Leuconostoc, Lactiplantibacillus, Pediococcus and Streptococcus genera.

    “Genes of the Wzy-dependent pathway have been reported only in Weisella, Leuconostoc, Lactiplantibacillus, Pediococcus and Streptococcus genera.”

    From Lactic Acid Bacteria Exopolysaccharides Producers: A Sustainable Tool for Functional Foods (2021) · cites this paper as [16]

    The Comparative Genomics section (page not provided) identifies Wzy polymerase and Wzx flippase genes in Lactococcus lactis, a genus absent from the claim's exclusive list. It also distinguishes the listed genera as those with reported sucrase-encoding genes, not the only genera with Wzy-dependent pathway genes. (LLM, conf=0.90)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • In S. thermophilus and Lb. bulgaricus, HePS production is favored under optimal growth conditions.

    “in S. thermophilus and Lb. bulgaricus HePS production is favored under optimal growth conditions”

    From Lactic Acid Bacteria Exopolysaccharides Producers: A Sustainable Tool for Functional Foods (2021) · cites this paper as [16]

    The ‘Regulation of polysaccharide synthesis’ section says production in some strains of S. thermophilus and Lb. bulgaricus appears to peak under conditions favoring optimal growth. The claim omits ‘some strains’ and presents this tentative observation as a general finding for both species. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • In Lacticaseibacillus casei, medium composition influenced exocellular polysaccharide production and its sugar composition.

    “in Lacticaseibacillus (Lcb.) casei, medium composition influenced exocellular polysaccharide production and its sugar composition.”
  • Polysaccharide production is influenced by pH, temperature, amino acids, vitamins and minerals.

    “Polysaccharide production is also influenced by pH, temperature, aminoacids, vitamins and minerals [16].”

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.
