Untargeted metabolomic profiles of paired cultures of four strains of Streptomyces bacteria isolated from a nature reserve in Minnesota, USA

This dataset contains untargeted metabolomic profiles of paired cultures of 4 interacting Streptomyces bacteria. The bacteria were originally isolated from a nature reserve in Minnesota USA. Daily samples of spot cultures grown in adjacent pairs on solid ISP2 medium were taken from day 2 to 6 in triplicate. Metabolites were obtained by cold methanol extraction, and liquid chromatography-mass spectrometry data was collected in both positive and negative ionisation modes. This dataset contains raw LC-MS (liquid chromatography mass spectrometry) data converted to the open-source .mzML format, of each sample run in both positive and negative ionisation modes. This includes, mass-to-charge measurements, elution time, and ion count intensity. These data were collected to investigate how the metabolism of the interacting strains changes in response to neighbouring bacterial cultures.
