Effects of gastrointestinal digested polyphenolic enriched extracts of Chilean currants (Ribes magellanicum and Ribes punctatum) on in vitro fecal microbiota

Publication date: Available online 3 December 2019Source: Food Research InternationalAuthor(s): Alberto Burgos-Edwards, Arantxa Fernández-Romero, Manuel Carmona, Israel Thuissard-Vasallo, Guillermo Schmeda-Hirschmann, Mar LarrosaAbstractChilean currants (Ribes magellanicum and Ribes punctatum) are wild polyphenol-rich berries with interesting bioactivities in several in vitro models. The aim of this study was to investigate the effects of the pre-digested PEE (polyphenol-enriched extract) in a simulated colon model. Fruits were extracted, submitted to simulated gastrointestinal digestion and further colonic fermentation with feces from healthy human donors. Samples were taken at 1, 4, 8 and 24 h of incubation, monitoring pH, ammonia, branched-chain fatty acids (BCFA), short-chain fatty acids (SCFA) and bacterial growth. FOS (fructooligosaccharides) and fecal slurry without treatments were positive and negative control, respectively. Both Ribes species reduced (p

Duval, Christophe PagnoutAbstractWhole cell luminescent bacterial sensors are used to monitor the bioavailability and toxicity of metals in aquatic media. Any rationale of the time response of such metal-detecting biosensors necessarily asks for the so-far missing measurement and modeling of the impacts of medium nutritional quality on lux-reporter expression and bioluminescence production. In this work, improvement of nutritional conditions in bioluminescence assays by increasing amino acid concen...

In this study, we investigated the antibacterial effect of LCE fruit extract (LCEE) against EPEC. The antibacterial activities of LCEE were examined by bacterial growth, time-kill curve, soft-agar motility, electron microscopy, and 96 well-microplate biofilm assays. We also investigated the bacterial mRNA expression of biofilm-associated genes (fliC, csgA, and fimA) by quantitative real-time PCR assays. LCEE was found to suppress the growth, time-kill curve, and spread of EPEC. It also reduced the biofilm formation in a dose-dependent manner. Morphological analysis using transmission and scanning electron microscopy reveal...

In this study, Ca-LTA Zeolite-diatomite-based adsorbents with purified diatomite loading rates of 15, 20 and 25 wt% are investigated by physicochemical, thermal and antibacterial characterizations. X-ray diffraction and FTIR spectroscopy analyses show that the purified diatomite is homogeneously dispersed into the Ca-LTA zeolite and that the zeolite crystalline structure is preserved. All analyses indicate that porous volumes, specific surface areas and initial water adsorption rates are affected by the mesoporosity nature of diatomite. Based on the water TPD profiles, the variation of the activation energy (Ea) and e...

In this study, the removal of Eth-Br from aqueous solutions by gamma irradiation has been fully investigated. Gamma irradiation was capable of achieving a near complete removal of Eth-Br in neutral and non-buffered aqueous solutions at an absorbed dose of 15 kGy. Various experimental conditions were studied and showed that the removal efficiency is not diminished. The addition of hydrogen peroxide (2%) to the irradiated solutions reduced the D50 and D90 by 50%. Modeling Eth-Br decomposition showed that the reaction followed pseudo first-order kinetics and reaches at least 90% removal under all experimental conditions. TOC ...

In this study, three tribenzoporphyrazines with dendrimeric peripheral substituents were subjected to in vitro antimicrobial photocytotoxicity study. One new magnesium(II) tribenzoporphyrazine with peripheral 3,5-bis(3,5-dimethoxybenzyloxy)benzylsulfanyl substituents was synthesized and subjected to physicochemical characterization using NMR, UV–Vis, and mass spectrometry techniques. In photochemical studies this molecule revealed moderate singlet oxygen generation ability (ΦΔDMF = 0.12, ΦΔDMSO = 0.13). The other two magnesium(II) tribenzoporphyrazines applied in the biological study were ...

Avian pathogenic E. coli (APEC), one type of ExPEC, causes avian colibacillosis, a disease of significant economic importance to poultry producers worldwide that is characterized by systemic infection. Some ExPEC strains as well as other pathogenic enterobacteria produce enterobactin, a catecholate siderop...

Human noroviruses (HuNoVs) cause sporadic and epidemic outbreaks of gastroenteritis in all age groups worldwide. We previously reported that stem cell-derived human intestinal enteroid (HIE) cultures support replication of multiple HuNoV strains and that some strains (e.g., GII.3) replicate only in the presence of bile. Heat- and trypsin-treatment of bile...
