Introduction
Humans live in a symbiotic state with microbes that inhabit our body. These have a profound effect on our bodily function and health, with
the greatest collection of microbes located in the intestinal tract (the gut microbiota). Through metabolising the foods we consume, the gut
microbiota helps provide energy, maintain immune homeostasis, and can affect our mood. Through tailored nutrition, such as prebiotics,
we can improve the human-gut microbiota interactions to drive health benefits. WellBiome® is a mineral enriched fibre-based prebiotic
designed to enhance gut microbiome diversity1. We evaluated the effect of WellBiome® on the gut microbiota of 6 different individuals using
a novel in vitro model, MiGut.
Methods
We investigated the effects of either the WellBiome® fibre complex or two compositional fibres (fibres with either a high or low degree
of polymerisation) on the gut microbiome composition and function. MiGut is a continuous triple-staged in vitro model that mirrors the phys-
iochemical conditions of the proximal (V1) to distal (V3) colon, which captures the complexities of the gut microbiome2. Models (12) were
individually seeded with 6 faecal donors from healthy adults aged 40 years or over. The microbial populations were allowed to stabilised prior
to a 2-week period where the prebiotics were dosed once daily. A further 2-week period was included with no prebiotic dosing to assess the ro-
bustness of prebiotic-induced microbiome changes. DNA from the first and last vessels were extracted thrice weekly for targeted quantitative
PCR3. Short-chained fatty acid (SCFA) analysis was done by gas chromatography mass spectroscopy.
