The ability of exopolysaccharides of Pseudomonas aureofaciens strains UKM B-111 and UKM B-306, components of insectofungicidal preparation Gaupsin, to influence the process of tumour formation caused by Agrobacterium tumefaciens. Bacterial polysaccharides, obtained on Kozer medium with glucose (possible alginates) blocked agrobacterium cell adhesion by 29-49%. Those obtained on the medium with sucrose polysaccharides (possible levans) by 30-75% inhibit later stages of tumour formation. The paper is presented in Ukrainian.
