Abstract- This paper addresses attitudes and forms of process modelling in biochemical engineering. Baker's yeast production in a fed-batch fermenter, at laboratory scale, is employed as case-study. Three modelling approaches are described and compared, viz.- the conventional mechanistic

sciences such as engineering of materials or agriculture [3]; the second direction is to models the kinetic processes that are involved in chemical reactions [4]. Many such models are available here. The present paper describes three variants of well the known kinetic models and presents the mathematical

The technology of biochemical processes works in a system of the Laboratories of integrated automation. The project goal is to have this process next some processes of thermodynamics, electro technique and engines. The control system is designed for a laboratory fermenter as a technological

that can express ordered sequence of events succinctly and unambiguously. The implementation of our mathematical and computational models in the Simpathica and XSSYS systems is described briefly. Several example applications of these systems to cellular and biochemical processes are presented: the two most

We present a streamlined data model for representation of biochemical processes which consistently adopts a perspective on these processes as molecular events. Our model references a small number of established foundational relations predominantly from RO and employs BFO as upper ontology

Abstract:- This paper deals with the design and the analysis of some nonlinear and adaptive control strategies capable to deal with the model uncertainties in an adaptive way for a complex and time varying bioprocess resulting from the association of a recycling bioreactor with an electrochemical reactor. The nonlinear controller design is based on the input-output linearizing technique. Computer simulations are included to demonstrate the performances of the proposed controllers.

Introduction In biochemical industries, most processes are carried out in a batch or fedbatch reactor. Think for example of the production of beer, penicillin or bakers yeast. These types of processes are characterized by their time-varying nature and their recipe-based processing. Furthermore

The search for alternative energy and fuels has motivated researchers to focus on renewable and sustainable means of getting them instead of relying on the conventional way of energy and fuel production. Anaerobic digestion is a biochemical process during which complex organic matter is decomposed

Abstract:- General framework for hybrid model based identification and optimization of biochemical processes is elaborated. An enhanced hybrid model of the fed-batch biosurfactant production process is presented. The evolutionary programming techniques are applied for the hybrid model

A compositional generic process control model is presented which has been applied to control enzymatic biochemical processes. The model has been designed at a conceptual and formal level using the compositional development method DESIRE, and includes processes for analysis, planning
