An antimicrobial substance produced by Pseudomonas cepacia B5(B5) against the bacterial wilt disease pathogen, Pseudomonas solanacearum, was isolated and identified in order to clarify the mechanism for disease suppression by B5. A filtrate of the B5 culture showed high inhibitory activity against this pathogen. The active substance was isolated in pure form by chromatography with a Diaion HP20 column and by high-performance liquid chromatography with a Jaigel GS220 column. On the basis of IR, NMR, and mass spectra, the antimicrobial substance was identified as 2-keto-D-gluconic acid(2KGA). The production of 2KGA and the destruction of the disease pathogen in a contaminated soil suspension to which the B5 strain was added, together with wheat bran, suggested that 2KGA might be involved in disease suppression by P. cepacia B5.
