Algorithms for evaluating the multiplicity of steady states in biotechnological process of lactic acid production

The numerical algorithms for the parameters evaluation of the continuous biotechnological process of lactic acid production in the conditions of multiplicity have been developed. The first algorithm generates the area of existence of multiplicity such as values of the flow and substrate concentration in the inlet flow. The second algorithm deals with calculation of steady state parameters at the fixed value of flow controlling the fixed value of productivity of the lactic acid. The third algorithm is focused on calculation of multiplicity parameters at the fixed substrate concentration in the inlet flow. The results obtained by means of these algorithms are represented.
