Nitrogen Substrate Impacts Microcystis aeruginosa Exometabolome Composition
Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.We used untargeted metabolomics to identify differences in the compounds exuded into culture media by three strains of M. aeruginosa grown on three N substrate treatments (NO3−, NH4+, and urea). Results showed that the usage of different N substrates changes the exometabolome of toxic and non‐toxic strains of M. aeruginosa.
