RNA-Based Stable Isotope Probing Suggests Allobaculum spp. as Particularly Active Glucose Assimilators in a Complex Murine Microbiota Cultured In Vitro

Table 1

Summary of bacterial taxa differing between “heavy” and “medium” fractions of the 2 h and 4 h incubations with 40 mM [U¹³C]glucose. Shown are relative frequencies (mean ± SEM) in the “heavy” and “medium” fractions. Differences between the mean relative abundances found in these fractions were determined by one-way ANOVA. n.d. = not detected; Uc = unclassified.
