Abstract:
... The microbial communities of kefir grains and kefir were evaluated over time using high-throughput amplicon sequencing. It was found that Lactobacillus kefiranofaciens and Lentilactobacillus kefiri consistently dominated kefir grains, whereas Lactococcus lactis dominated kefir. Many other bacteria and yeasts were detected that comprised the minor population of kefir grains and kefir. The community ...
... Wooden vats are used in the production of some traditional cheeses as the biofilms on wooden vat surfaces are known to transfer large quantities of microbes to cheese. However, very few studies have investigated the microbial composition of biofilms on newly developed wooden vats and how communities assemble and evolve. In the present study, the microbial communities of biofilms were characterized ...
... Lactobacillus rhamnosus and fructooligosaccharides (FOS) have been widely studied so far. However, the effects of L. rhamnosus on the intestinal microecological environment at the species level and the effect of different proportions of FOS on L. rhamnosus colonization in different parts of mice intestine are still unclear. The study results indicated that the specific bands of enterobacterial rep ...

Abstract:
... In the present study, the effects of cooked rice (CR) with added fructo-oligosaccharide (FOS) on faecal flora were studied by a simulated in vitro digestion and fermentation method. The total carbohydrate content, pH, and short-chain fatty acids (SCFAs) were determined during in vitro digestion and fermentation. The change in the bacterial phase distribution after the fermentation was also analyse ...
... To prepare pumpkin juice (PJ) rich in coenzyme Q10, this study analyzed the chemical composition, antioxidant activity, and gut microbiota of pumpkin juice fermented by Rhodobacter sphaeroides (RPJ). The number of viable bacteria in the juice reached 2.8 × 10⁸ CFU/mL; the fermentation process mainly consumed glucose and sucrose; the total sugar content was reduced, β-carotene was reduced, and a ne ...

Abstract:
... Dendrobium officinale is widely consumed owing to its numerous beneficial effects. We aimed to characterize polysaccharides of Dendrobium officinale (DOP) from the stems of Dendrobium officinale Xianhu 2 and clarify whether it benefit the intestinal microbiota and the immune system. The DOP weighed 291 kDa and comprised mannose, glucose, galactose, and rhamnose at 59.31:33.31:1.00:0.51 M ratio. In ...
... In this study, shell-core fibers were successfully prepared by using Eudragit S100 (ES100) and poly(vinyl alcohol) (PVA)/pectin (PEC) through coaxial electrospinning technology. The electrospun fiber was characterized by attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) and X-ray diffraction (XRD). Thermo-gravimetric analysis (TGA) showed that the coaxial electrospun ...
... The correlation of antioxidant activity and prebiotic effect about oat phenolic compounds was invested, while there exists limited studies. Free and bound phenolic compounds were separated from ethyl acetate, n-butanol and aqueous fractions. Fluorescence in situ hybridization was used to investigate gut microbiota of in vitro fermentation samples. The results showed that ethyl acetate fraction pos ...
... Ochratoxin A (OTA) is a secondary fungal metabolite produced by Aspergillus and Penicillium spp. OTA contamination of food and animal feed has been attracting increasing concern in view of its toxicity, such as nephrotoxic, teratogenic, embryotoxic, genotoxic, neurotoxic, carcinogenic, and immunosuppressive effects. The widespread contamination of OTA in food and multiple toxicity of OTA have prom ...
... This study was to investigate the structure and rat fecal microbial fermentation properties of a polysaccharide fraction (PHP2) isolated from the red marine alga Porphyra haitanensis. PHP2 was characterized as a sulfated glucogalactan, with a hypothetical backbone structure of →4)Gα(1→6)G4Sβ(1→4)Glc(1→ and a side chain of Man(1→6)Glc. PHP2 had an irregular spherical chain conformation. The 16S rRN ...

Abstract:
... Pea protein has attracted the attention of consumers owing to its non-GMO, hypoallergenic, and high nutritional value, however, the beany flavor limits its applicability. Hence, GC–MS and GC-IMS were applied to assess the influence of Saccharomyces cerevisiae and Lactobacillus plantarum on the beany flavor of pea protein. Specifically, 51 and 65 volatiles were detected in pea proteins via GC–MS an ...
... This is the first report on a polysaccharide (RCJ2-Ib) isolated from Rosa Chinensis Flos. RCJ2-Ib was obtained through the extraction with water, precipitation with ethanol, separation with DEAE-52 column and purification with DEAE-Sepharose Fast Flow column and Sephadex G100 column. GC, FT-IR and NMR analyses revealed that RCJ2-Ib (3.3 kDa) was a 1,4-linked polymannuronic acid containing substant ...
... Microcapsules can provide better protection for probiotics during freeze-drying and gastrointestinal digestion. This study aims to investigate the effect of microencapsulation using the product of the Maillard reaction of whey protein and carboxymethylated dextran (CM. dex) on the viability of Lactobacillus plantarum LP90 (Lₚ) as related to freeze-drying, gastrointestinal tolerability and storage ...

Abstract:
... Polybrominated diphenyl ether has become a widespread environmental pollutant in aquatic environments. BDE-209, a prominent PBDEs found in the environment and wildlife, has been proven to cause oxidative stress, immune damage and endocrine system disorders in fish. However, the effects of BDE-209 on the intestinal health of fish remain unclear. This research aimed to determine the effects of BDE-2 ...
