✦ Synopsis

Bacillus subtilis produces peptidolipid compounds of the iturin group that have been shown to have antifungal properties, but not all fungal species are sensitive to these compounds. In this study, the activity of iturin A, produced by B. subtilis strain B-3, was tested. Paper disks impregnated with various concentrations of iturin A were placed on agar plates seeded with conidia of toxigenic species of Fusarium, Gerlacia, Penicillium or Aspergillus. Most isolates were inhibited at iturin A concentrations as low as 4 ~g/disk. Penicillium italicum, P. viridicatum, A. ochraceus and A. versicolor were most strongly inhibited by the iturin whereas P, citrinurn and A. parasiticus were least sensitive to iturin A.

Aqueous solutions of organic extracts of Nigrospora oryzae in the concentration range 0.1 to 1000 ~g / c m ~ were found to inhibit both spore germination and mycelium growth of Fusarium avenaceum, F. culmorum, F. gramminearum, F. oxysporum, F. equiseti, F. lateritium and Botrytis cinerea.
