Model based optimization can be successfully used to improve the design and operation of bioreactors. In this contribution, we present a review of this area, especially focusing on the dynamic optimization of fed-batch bioreactors, a class of problems which has attracted (and continues to receive) huge attention.
The increase of the use of biofuels, like bioethanol, has presented new challenges to engineering problems. The optimization of bioreactors is...
For bioprocess optimization, plug-flow behaviour is an option in many cases. However, many bioprocesses require oxygen to be supplied into the bioreactor. Plug-flow-like behaviour with aeration is feasible in a series of bioreactors. This article reviews the range of aerated bioreactors available for the approximation of plug-flow behaviour and introduces a new type of serial air-lift bioreactor.
Our design project involved the modeling and optimization of a facility equipped with two production lines, each capable of producing a different MAb. Each line includes four produc-tion bioreactors feeding a single purification train. The two production lines have their own independent main equipment,
This review surveys recent applications of design‐of‐experiments (DoE) methodology in the development of biotechnological processes. Methods such as factorial design, response surface methodology, and (DoE) provide powerful and efficient ways to optimize cultivations and other unit operations and procedures using a reduced number of experiments.
Bioreactors are important inevitable part of any tissue engineering (TE) strategy as they aid the construction of three-dimensional functional tissues. Since the ultimate aim of a bioreactor is to create a biological product, the engineering parameters, for example, internal and external mass transfer, fluid velocity, shear stress, electrical current distribution, and so forth, are worth to be ...
