Figures & data
Figure 1. Concentration of methanogen DNA (ng/gww) in human faecal samples over a 14 week period. •λ, volunteer 2; □, volunteer 6; ▴, volunteer 8; ▾, volunteer 5 and • volunteer 4.
Figure 2. Relationship of methanogen 16S rDNA gene abundance and faecal butyrate concentration. Methanogen and butyrate concentration averaged over 12 weeks of the study. Error bars show standard error.
Figure 3. Relationship between faecal pH and faecal butyrate concentration. Error bars show standard error.
Figure 4. Relationship between methanogen 16S rRNA gene abundance and faecal pH for individuals in which methanogens were detected. Error bars show standard error.
