Study Notes

Biochemical Engineering

Biochemical engineering is the extension of chemical engineering to systems using a biological catalyst to bring about desired chemical transformations.
It is concerned with conducting biological processes on an industrial scale, linking biological sciences with chemical engineering.

Biotechnology

Biotechnology is the use of living organisms, or substances from those organisms, to make or modify a product.
It includes techniques used for the improvement of the characteristics of economically important plants and animals and for the development of microorganisms to act on the environment.

Applications of Biotechnology

Biosensors: biological entities (e.g., bacteria) are used to monitor levels of certain chemicals.
Recombinant DNA or cell fusion: initiated and developed by pure scientists, producing new breed of cells in minute quantities.

Biochemical Engineering Laboratory-Scale to Industrial Scale

Laboratory-scale: development of small-scale processes.
Industrial scale: large-scale bioreactor design and operation.

Role of Biochemical Engineers

Biochemical engineers work with biological scientists to carry out bioprocesses on a large scale.
They aim to obtain the best biological catalyst (microorganism, animal cell, plant cell, or enzyme) for desired applications.
They design and operate bioreactors to create the best possible environment for the catalyst to perform.
They develop methods to separate the desired product from the reaction mixture in the most economical way.

Issues in Process Development and Design of Bioprocesses

Understanding the basic sciences (microbiology, biochemistry, molecular biology, genetics, etc.) for the process involved.
Considerations of reaction kinetics and bioreactor design.
On-line optimization algorithms for enhancing bioprocess operability and economical operation.
Product separation and purification with maximum purity and minimum costs.
