    The mathematical model for cellulase fermentation was constructed and computer simulation of the fermentation processes at 28 and 30degC, respectively, were done using this mathematical model. Genetic algorithm (GA) was used in the optimization of the model parameters. The simulation results showed that the mathematical model was correct and the simulation fitted . A validation experiment gave mL H2/g TVS resulting to a 12% increase. The R2 was above implying the model was adequate to navigate the optimization space. Therefore, these findings demonstrated the feasibility of conducting optimized biohydrogen fermentation processes using response surface methodology.

    INTRODUCTION. For an industrial fermentation process fermentation medium and fermentation process condition plays an critical role because they effect the formation, concentration and yield of a particular fermentation end product thus effecting the overall process economics therefore it is important to consider the optimization of fermentation medium and process . Optimization and scale up of industrial fermentation processes. -up criteria and the process conditions in the culture vessels thus may differ significantly and since any strategy and model can only insufficiently consider and reflect the highly complex interdependence and mutual interaction of fermentation parameters, successful scale up.

      Achieving the same process conditions within the perfectly mixed model would require increasing the cooling rate capacity by a minimum of one order of magnitude. To obtain a product with the same properties as in the perfectly mixed model, fermentation within the spheroconical tank would need to be stretched out beyond hours. Modeling, Optimization and Control of Zinc Hydrometallurgical Purification Process provides a clear picture on how to develop a mathematical model for complex industrial processes, how to design the optimization strategy, and how to apply control methods in order to achieve desired production target. This book shares the authors’ recent ideas.

Processes, an international, peer-reviewed Open Access journal. Dear Colleagues, Unlike other areas of application where the word ‘optimization’ is often misused to just describe an improvement of a process without clearly specifying the underlying criterion, for fermentation optimization, maximizing the product or cell yield, or minimizing substrate expenditure and fermentation.

Thus, this work presents the modeling (in industrial scale) of the ethanol fermentation process and a control structure with two layers that allows the process control and production optimization.

The rest of the paper is organized as follows. A simple mathematical model, taking into account substrate limitation and inhibition by both the product ethanol and the substrate, was proposed and used to interpret experimental data from a batch alcohol fermentation process, conducted at two.

ABSTRACT Artificial intelligence techniques are important tools for modelling and optimizing the solid-state fermentation (SSF) factors. The performance of fermentation processes is affected by numerous factors, including temperature, moisture content, agitation, inoculum level, carbon and nitrogen sources, etc.

The primary kinetic model was then applied in the second phase to determine the optimal control policy for a fed-batch fermentation process and to retune the kinetic model. Abstract This paper presents a framework for modeling and optimizing the glutamic acid fermentation process using computational intelligence techniques.

Considering the special characteristics of such an industrial process, we propose a two-phase optimization strategy to maximize the conversion rate and product concentration of the glutamic : Shouping Guan. The development of the fermentation process and its optimization is seriously challenged by a lack of the knowledge about scale up and other issues such as.

The book covers all aspects of fermentation technology such as principles, reaction kinetics, scaling up of processes, and applications. The 20 chapters written by subject matter experts are divided into two parts: Principles and Applications.

Thus, toward developing good, reliable, and simple but highly predictive models that can be used in the future for optimization and process control applications, in this paper an unstructured and a cybernetic model are proposed and compared for the simultaneous saccharification‐fermentation process (SSF) for the production of ethanol from.

The most recent rise in demand for bioethanol, due mainly to economic and environmental issues, has required highly productive and efficient processes. In this sense, mathematical models play an important role in the design, optimization, and control of bioreactors for ethanol production.

Such bioreactors are generally modeled by a set of first‐order ordinary differential equations. medium optimization is very important for the advancement of fermentation processes 5.

Designing of suitable media components for cultivation have cosiderable effect on production. Products yield could be improved by the application of statistical experimental design techniques which will economize time and cost more than routine single factor.
