Article Abstract

As natural polymers, Lactiplantibacillus plantarum exopolysaccharides (EPS) possess a wide range of bioactivities but suffer from low yields and unclear relationships between functional activity and structure. To this end, the chemical structure and bioactive properties of EPS from Lactiplantibacillus plantarum MY04 were investigated. As a result, three polysaccharide fractions (EPS-1, EPS-2, EPS-3) were separated and purified, of which EPS-2 had better antioxidant activity and α-glucosidase inhibitory ability. More importantly, EPS-2 can significantly enhance insulin sensitivity in HepG2 cells by upregulating enzyme activities in the glycolytic pathway and mitigating oxidative stress-induced damage. In addition, the structural characterization of EPS-2 was also comprehensively elucidated. It was found that EPS-2 was mainly composed of mannose with a molecular weight of 2.3 × 10 Da, and its main chain structure is →3)-Manp-(1 → 2)-Manp-(1 → 2,6)-Manp-(1 → 2,6)-Manp-(1→, providing a theoretical basis for understanding the relationship between structure and function of polysaccharides.

The inhibitory effects of Lactiplantibacillus plantarum on inflammatory responses are known, but its action mechanisms in oxidative stress, immunomodulation, and intestinal homeostasis remain of interest. Accordingly, we investigated the protective effects of Lactiplantibacillus plantarum SCS2 (L. plantarum SCS2) against sodium dextran sulfate (DSS)-induced colitis in mice as well as elucidated its impact on inflammation, oxidative stress, and intestinal microbiota.

, a lactic acid gut bacterium, uses exogenous quinones to facilitate extracellular electron transfer (EET) via type II NADH dehydrogenase (Ndh2). To probe Ndh2 specificity, we designed and evaluated a library of biogenic amine-substituted 1,4-naphthoquinones in an Ndh2-dependent EET assay. Analysis of mediator Ndh2 binding interactions revealed that activity correlates with key binding interactions.

Genome-scale metabolic models (GEMs) are widely used in systems biology to investigate metabolism and predict perturbation responses. Automatic GEM reconstruction tools generate GEMs with different properties and predictive capacities for the same organism. Since different models can excel at different tasks, combining them can increase metabolic network certainty and enhance model performance.

The current work aimed to investigate the effects of fermentation of , , and on the physicochemical, electronic sensory evaluation, and flavour characteristics of heat-sterilized tomato juice (HTJ). The results indicated that LAB fermentation significantly decreased the pH, sucrose, and glucose, and lactic acid was increased. E-nose and tongue analyses revealed that the response to organic sulfides, terpenoids, and sourness increased after LAB fermentation HS-SPME-GC-MS and OAV revealed that heat-sterilization resulted a significant loss of aroma compounds (38.
