(A) Overview of qualitative evaluation of antagonisms assays assigned to inhibition, minor inhibition, and no inhibition. Strains P5_B2 and P8_B2 were not naturally competent, and no NRP mutants could be created. (B) Overview of NRP production of wild-type soil isolates based on the detection of surfactin and plipastatin in the extracts by ESI-MS. The production of the compounds was classified as production (detected), reduced production (detected but at a lower level), and no production (undetected).
