title: [Interrelations of infusoria with Azotobacter and their influence on plants].
abstract: Symbiotic coexistence of infusoria Colpoda steinii with bacteria of Azotobacter genus has been investigated. It is shown that when infusoria are incubated during 3 days with the cells of A. vinelandii IMV D-7076 selected in the logarithmic phase of growth, the number of colpods increased 19 times, and with A. chrooccum 20--only 1.8 times. After 6 days of incubation with bacteria selected in the phase of stationary growth the number of infusoria increased with A. vinelandii 10 times, and with A. chrooccum 20 - 9.2 times. Treatment of seeds by the bacterial mix of A. vinelandii and C. stenii stimulates their germination, growth of roots and sprouts at early stages of plants development as compared with the use of cultures of monobacteria. It is evident that infusoria Colpoda steinii as well as the bacteria of Azotobacter genus secrete biologically active substances which accelerate growth and development of plants.
