Abstract
Formation of plasmin-like and activator proteinases by Bacillus firmus cells immobilized in polyacrylamide gel was studied. Immobilized cell s were shown to differ from free cells by a higher rate of enzyme synt hesis and a longer period of high-level enzyme production. The total p lasmin-like activity and activator activity increased 2.6- and S-fold, respectively; the stability of the system was enhanced 2-fold; and th e affinity of the proteinase complex to fibrin and plasminogen increas ed 1.5-fold.
