Interpretive Summary:

Technical Abstract: Soil bacterial cultures, which are effective against Fusarium dry rot, have been isolated and are being developed as biological control agents. One of the best isolates is Enterobacter cloacae NRRL B-21050. When this strain was grown in liquid culture and extracted with organic solvent, several antifungal compounds were isolated from the extracts. Compounds identified in extracts from culture grown in Sabouraud maltose broth include phenylacetic acid, tyrosol and tyrosol-alpha-acetate. When a medium higher in tryptophan was used, the major antifungal metabolite isolated was indole-3-acetic acid.
