Figure Lengend Snippet: A | After pre-culturing each of the 16 species of the community for one growth cycle, we adjusted optical density of each culture, pooled them at equal volume and inoculated 96 resource environments, with each condition replicated 8 times. Each culture was serially transferred for 16 days, with 1% of the culture transferred every 48 h. B | At each transfer, we measured OD 600 of each community. In addition, we conducted 16S rRNA sequencing of all communities at the end-point and measured growth traits of each of the dominant species ( A. caviae, P. chlororaphis, C. koseri ) in monoculture in all carbon levels in the absence of R2A.

Panel B explains analytical procedures of the community and single-species experiments.
Article Snippet: R2A medium was prepared by dissolving R2A Broth powder (Neogen, UK) in M9 minimal medium.
