5/5. MetaFlowTrain confirms that specific bacterial exometabolites, not media depletion, drive microbial antagonism.
🦠 Pseudomonas R401 WT suppresses SynCom growth via known inhibitory exometabolites.
❌ A triple mutant loses inhibitory power.

3/5. MetaFlowTrain reveals how soil conditioning alters microbial assembly/exometabolite output.
🦠 SynComs exposed to plant-conditioned peat undergo major community shifts & consume key metabolites (α-KG, fumarate).
🌱 BF SynCom-derived exometabolites impact Arabidopsis germination & root growth.

2/5. MetaFlowTrain cultivates diverse microbes & collects their exometabolites under continuous nutrient flow.
🌱 Using sterile peat extract, we grew 11 bacterial & 4 fungal strains from the Arabidopsis root microbiota.
💥 Exometabolite profiles differed significantly by strain.
