Light and electron microscopical studies on the effect of a culture filtrate of Erwina herbicola B 247 and herbicolin A on Fusarium culmorumThe effect of a culture filtrate of Erwinia herbicola B 247 and the antibiotic herbicolin A, respectively, on the hyphae of Fusarium culmorum was studied in vitro using light and electron microscopy. The light microscopy revealed a swelling and disruption of the hyphae tips with a release of cytoplasm. Ultrastructural investigations demonstrated the appearance of electron‐dense material of a round or tubular structure in the cell wall. On its inner side, an accumulation of electron‐dense material formed a spongy structure associated with the altered plasma membrane. Finally, a complete dissolution of the cell wall was observed.
