Detection of the anti- Erwinia metabolite produced by P. polymyxa M-1. (A) Detection of the antibacterially acting metabolite by bioautography. Supernatants prepared from strain M-1 grown in GSC medium for 36 h were separated by TLC and sandwiched with indicator strain E. carotovora. The inhibiting band at R f 0.36 was circled. (B) MALDI-TOF-MS analysis of the antibacterial compounds detected by bioautography.
