Abstract
The microbial community of the human large intestine plays an important role in nutrition and health. Molecular analyses have revealed the diversity of gut bacteria; although some dominant species are abundant in most individuals, humans show considerable inter-individual variation in the strain composition of their intestinal microbiota. It is helpful therefore to define broad functional groups (‘clubs’) that share one or more characteristics of interest. This approach has been applied to the formation by microbial fermentation of short chain fatty acids that are actively absorbed by the host as energy sources. A combination of targeted molecular detection and information on cultured isolates is helping to reveal the impact of diet upon groups responsible for the fermentation of particular dietary carbohydrates and the formation of butyrate, and should provide the basis for theoretical modelling of this complex community.
