GNPS - Two-Species interaction through pH stabilisation

Here we apply metabolomics to study the interaction of two co-isolated model organisms, Xanthomonas retroflexus and Paenibacillus amylolyticus. When cultured in close proximity on agar plates Xanthomonas retroflexus induces a clear morphological response from Paenibacillus amylolyticus, leading to enhanced growth of Paenibacillus amylolyticus. Application of 2D spatial metabolomics shows how Xanthomonas retroflexus influences the chemical environment by production specific metabolites.
