The influence of different types of ß-glucans on the gut microbiota of rats fed milk gels
The effect of glucans on gut microbiota functions is still unclear. Therefore, this study was undertaken to describe the influence of structurally different ß-glucans (oat ß-glucan, curdlan and scleroglucan) on the structure of the gut microbiome in rats. The structure of intestinal microbiota was e...

| Summary: | The effect of glucans on gut microbiota functions is still unclear. Therefore, this study was undertaken to describe the influence of structurally different ß-glucans (oat ß-glucan, curdlan and scleroglucan) on the structure of the gut microbiome in rats. The structure of intestinal microbiota was evaluated by high-throughput sequencing of the16S rRNA gene. Firmicutes and Bacteroidetes were the dominant bacterial phyla in all animals. Oat ß-glucan contributed to a higher prevalence of bacterial genera Clostridium sensu stricto and Blautia, whereas curdlan increased the relative abundance of Akkermansia muciniphila. A positive correlation was noted between the relative abundance of Streptococcus bacteria and the growth rate of rats. The present study demonstrated that the consumption of non-acidified milk gels or acidified milk gels with a β-glucan dose recommended by EFSA (3.0–4.0 g per day) for 28 days did not induce significant changes in the structure of the gut microbiome in rats. |
