[Equations of the relationship of biomass growth and metabolic product biosynthesis in the presence of an inhibition effect].

Equations of relationship between the rate of metabolite biosynthesis q and specific rate of the culture growth mu were set up theoretically on the basis of kinetic equations connecting q and mu with the environment factor S. The inhibiting effect of S on q and/or mu was considered in the Ierusalimsky or Andrews equations. The equations of relation q (mu) provide consideration of various experimental relations. The equation choice is based on the character of the convexity of concavity of the experimental curves of relation q (mu). Equations q(mu) posess a less number of constants than both equations q (S) and mu (S). It was found that when S affected mu as a limiting or inhibiting factor depending on its value, relation q(mu) was not simple. In this connection it is not convenient for use in mathematical description of the process and control problems.
