RNA-Based Stable Isotope Probing Suggests Allobaculum spp. as Particularly Active Glucose Assimilators in a Complex Murine Microbiota Cultured In Vitro
Relative abundance of bacterial taxa in different density RNA-SIP fractions. Stacked barplots showing the average community composition of different density RNA-SIP fractions from the uncultured control (0 h control) and from the 2 h and 4 h incubations in minimal medium with 40 mM [U13C]glucose. Shown are the 40 taxa with the highest mean relative abundance across all samples. indicates abundant taxa that are significantly different () or are tending to differ () () in relative abundances in “heavy” fractions compared to their respective “medium” fractions determined by one-way ANOVA.
