Modeling and steady state simulation: production of xanthan gum from sugarcane broth

The work is focused on developing a mathematical model for continuous process of xanthan gum production. The main objective of the study is to simulate the model, observe the behavior of substrate consumption, biomass and product formation with respect to dilution rate and determine the optimum dilution rate for which the reactor is to be designed. Systems with and without recycling of cells are considered and the optimum dilution rate is found. For the kinetic parameters used, the optimum dilution rate for the system with no recycling is 0.205 and 0.35 h(-1) for the system that includes recycling of cells.
