Detection and isolation of typical gut indigenous bacteria in ICR mice fed wheat bran and wheat straw fibre

Anti-obesity effects of Laminaria japonica fucoidan in high-fat diet-fed mice vary with the gut microbiota structure

“…Muribaculaceae (phylum Bacteroidota) was reported to participate in complex carbohydrate degradation 40 and Clostridia_UCG-014 (phylum Firmicutes) was reported to be associated with anti-obesity effects. 41 The determinants of bacterial OTUs involved in Fuc Lj consumption were demonstrated as a genus of Muribaculaceae and a genus of Clostridia_UCG-014, indicating their major roles in Fuc Lj consumption.…”

Furthermore, the anti-obesity effects of Fuc Lj showed that HFD enhanced the body weight gain, adiposity index and fat accumulation, but the symptoms mentioned above were significantly decreased after the administration of Fuc Lj in the HFD-Fuc Lj group and the HFD-P-Fuc Lj group.…”

Antioxidant capacity of wheat bran fermented with gut indigenous Bifidobacterium and its antagonistic effect on food‐related pathogens in vitro

“…WB contains arabinoxylan as well as a small amount of low‐molecular‐weight saccharides (Khorasaniha et al, 2023). Previous studies have reported that some isolates from the human gut, such as B. adolescentis , B. longum, Bacteroides ovatus, Phocaeicola vulgatus , L. johnsonii , and L. reuteri , can utilise and ferment arabinoxylan (Takei et al, 2022; Van Laere et al, 2000). Furthermore, lactate produced by the bacterial species of Bifidobacteria and Lactobacilli can be converted to SCFAs by other gut commensals (Peterson et al, 2022).…”

“…WB contains approximately 17% (w/w) protein, 4% fat, 18% starch, 40% insoluble fibre, and 3% soluble dietary fibre (Ye et al, 2021). Lipids in WB have been reported to exhibit cholesterol-reducing activity, whereas the protein hydrolysates have antioxidant and immunomodulatory properties (Talawar et al, 2020;Zou et al, 2020). The dietary fibre of WB contains arabinoxylan, cellulose, and lignin, which may inhibit cardiovascular disease, obesity, diabetes, colitis, and colon cancer through fermentation by the gut microbiota (Khorasaniha et al, 2023;Nie et al, 2022).…”

“…Dietary WB supplementation increased the abundances of Lactobacillus johnsonii and Limosilactobacillus reuteri in mice caecum (Takei et al, 2022). In contrast, WB supplementation tended to lower caecal Desulfovibrio in the mice; Desulfovibrio produces inflammation‐inducing lipopolysaccharides and hydrogen sulphide (Murros et al, 2021).…”
