13C-enriched bacterial genera identified by calculating the EF in the ST (A) and LT (B) soil amended with the labelled consortium SC AMBk after 0 (after 1 h of incubation), 7, 15 and 30 days of incubation. The colour scale reflects the mean value of the EFs, and the size scale represents the mean relative abundance of each genus in the heavy fraction of the 13C treatment. The figure shows the genera whose EF was higher than 0 at least at one time point, showing significant change in their value through time (p < 0.05), and whose relative abundance was higher than 0.5% in at least one time point. White circles represent EFs lower than 0.01
