Fig. 5: Data from 16S rRNA gene sequencing showing the microbial community at the genus level for the sediment inoculum at day 0 (left bar) and sample from the day 40 experimental endpoint (right bar).

Where sequences could not be resolved at genus level, the highest possible taxonomic rank was resolved and is indicated in brackets e.g., ‘(O_Microtrichales)’ indicates this sequence could only be resolved at order level and was most closely matched to Microtrichales.
