[Factors increasing exoprotease activity in the associative cultures of coryneform bacteria]

Specific features of the effect of Artrobacter citreus on the biosynthesis of fibrinolytic enzymes of Nocardia sp. 1 were investigated during the combined cultivation of both microorganisms. It was demonstrated that an increase in the synthesis of fibrinolytic proteases in the mixed culture of A. citreus and N. species 1 was determined by the compounds containing in the A. citreus supernatant rather than by the nutrient deficiency.
