[A new metabolite with fungistatic and bacteriostatic activity, produced by strain L-30 of Flavobacterium sp]. / Novyi metabolit s fungistaticheskoi i bakteriostaticheskoi aktivnost'iu, produtsiruemyi shtammom L-30 Flavobacterium sp.

Flavocin, an agent with fungistatic and bacteriostatic activities, was isolated from the culture of Flavobacterium sp. L-30. The data on the physico-chemical and biological properties of flavocin A, the major active component, are presented. The component was identified with metabolites of the genus Flavobacterium and other genera of nonsporulating bacteria. Flavocin was highly efficient in the treatment of various farm crops. The antagonistic effect of flavocin was observed under field conditions in growing sugar beet, barley, spring wheat, potato and grape. Presowing and nonradical exposure to flavocin lowered the affection of the plants with brown patch, scab, soft rot and oidium.
