Microbial community composition in (non-)extractive chain elongation continuous reactors at ASV level. Initial substrates were l-lactate and acetate. Top 30 ASVs are displayed and relative abundance values ≥ 1% are shown. Independent biofilm samples were analysed and shown as duplicates. Sampling days are shown in Additional file 1: Fig. S4. Taxonomy was assigned based on SILVA 138 SSU Ref NR 99 database
