Fig. 1: Partitioning of attached and planktonic syntrophic communities in FBRs.

A A schematic of the custom FBRs developed to simulate biphasic growth of microbial communities by recirculating growth medium upward through a column of sediment. Temporal growth dynamics of planktonic (B) and sediment attached (C) phases of the microbial community. Metabolite profiles provide confirmation syntrophic growth via the oxidation of lactate to acetate by Dv (D) and the production of methane by Mm (E). The grey opaque background bars indicate the first 48 h of growth in batch culture mode (beginning of Day 1 through the end of Day 2) in FBRs prior to fluidization (i.e., Day 1 through Day 6, indicated in bold typeface); grey triangles represent timepoints (from Day 1 through Day 6), when SynComs from planktonic and attached phases were harvested for DNA and RNA profiling. All data presented as mean values +/− standard deviation (95% Confidence Interval) across 3 replicate FBRs (n = 3). Source data are provided as a Source Data file.
