title: [Combined immobilized cultures producing fibrinolytic proteinases].
abstract: The authors obtained combined immobilised systems composed of a culture producing fibrinolytic proteinases and a stimulating strain. The optimal ratio between the two cultures in gel was selected at a high starting cell density. Highly stable immobilised cultures were produced by growing the cells in gel particles. The interrelationship of the partners was studied in the binary immobilised culture. The biosynthetic activity of the system fell down to the level of a monoculture when the cells of the stimulating strain were eliminated from gel. The producing and stimulating strains are at equilibrium in associative immobilised cultures obtained by growing the cells in gel, and Arthrobacter is not eliminated. The mechanism of biosynthesis stimulation in a combined immobilised culture has been studied. Apparently, the procedure of immobilisation and the action of a stimulating compound exert the synergistic effect.
