Exopolysaccharides From Lactobacillus delbrueckii subsp. bulgaricus OLL1073R‐1 Enhance Macrophage Bactericidal Activity Through IL‐12‐Dependent Macrophage–NK Cell Crosstalk

Microbiology and Immunology, EarlyView.
ABSTRACT Exopolysaccharides (EPS) produced by Lactobacillus delbrueckii subsp. bulgaricus OLL1073R‐1 have been reported to exert immunomodulatory effects, primarily in antiviral responses; however, their role in antibacterial host defense remains unclear. Here, we investigated whether EPS enhance macrophage‐mediated killing of Streptococcus pyogenes, a

Non-disruptive matrix turnover is a conserved feature of biofilm aggregate growth in paradigm pathogenic species

mBio
Bacteria form multicellular aggregates called biofilms. A crucial component of these aggregates is a protective matrix that holds the community together.

Gut microbiota as a novel therapeutic target for eating disorders and obesity

British Journal of Pharmacology, EarlyView.
The graphical abstract highlights the bidirectional interaction between the gut microbiota and central homeostatic and hedonic mechanisms regulating food intake, which contributes to overweight and obesity. It also illustrates emerging microbiota‐based biomarkers and therapeutic strategies (including prebiotics, probiotics, postbiotics, synbiotics and ...

Antitumour Activity of Grifola frondosa Exopolysaccharides Produced by Submerged Fermentation Using Sugar Cane and Soy Molasses as Carbon Sources

Food Technology and Biotechnology, 2011
Grifola frondosa is an edible Basidiomycete and produces exopolysaccharides (EPS) known for their antitumour activity. The objectives of this study are to produce exopolysaccharides in submerged fermentation using alternative carbon sources (sugar cane ...

Leaf Structure and Hormonal Balance Modulate Host‐Specificity and Pathogenicity of Botrytis cinerea

Plant, Cell &Environment, EarlyView.
ABSTRACT Botrytis cinerea, a highly successful necrotrophic fungal plant pathogen, demonstrates a remarkably broad host range, yet the precise factors governing its host specificity and its ability to coexist non‐pathogenically with plants remain unclear. This study systematically assessed host preference in a series of B. cinerea agricultural isolates,

Sugars as Central Integrators of Plant Immunity and Stress Responses

Plant, Cell &Environment, EarlyView.
ABSTRACT Sugars are fundamental metabolites that sustain plant growth and development, but accumulating evidence demonstrates that they also function as regulatory hubs in plant defence. In this review, we synthesise current knowledge on how carbohydrate dynamics coordinate metabolism, signalling, and structural responses to shape plant resistance ...

Microbial Partnerships for Sustainable Soybean Cultivation: Mechanisms, Applications and Prospects

Plant, Cell &Environment, EarlyView.
ABSTRACT Soybean production is increasingly threatened by fluctuating environmental conditions and nutrient limitations. While synthetic fertilisers can alleviate these constraints, their excessive use has raised concerns regarding long‐term soil health. Consequently, leveraging beneficial soil microbes, a diverse group of microorganisms that reside in

Utilization of purple sweet potato synbiotic drink as a source of lactic acid bacteria exopolysaccharides for immunomodulation

Pharmaciana
Immunomodulators, such as exopolysaccharides (EPS), can be found in products processed through lactic acid bacteria (LAB) fermentation. Purple sweet potatoes have the potential to be used as ingredients for making synbiotic drinks because of the high ...
