40
What is bioprocessing?
It is a branch of biotechnology and it is the application of natural or genetically manipulated whole cells/tissues/organs etc to produce industrially or medically important products
41
What is the main difference between chemical processing and bioprocessing?
Chemical processing uses chemical reactions in reactors, while bioprocessing uses living cells as bioreactors to produce products.
42
What kinds of products are obtained from bioprocessing?
Cells, small molecules, and enzymes.
43
What do living organisms in bioprocesses require for growth and production?
Specific conditions like temperature, pH, and nutrients.
44
What risk is associated with the culture medium in bioprocessing?
It may support unwanted cell types, leading to contamination.
45
Why are bioproducts difficult to handle in bioprocessing?
They are sensitive to external conditions like temperature and pH.
46
Why is separation important in bioprocesses?
Because the product is usually very diluted and mixed with byproducts (metabolites).
47
What is a key issue with byproducts in bioprocessing?
Metabolites are produced and need to be removed from the medium.
48
What kind of reactions can cells perform in bioprocessing?
Difficult or complex biochemical reactions.
49
What can cells convert in bioprocessing?
Basic nutrients into valuable products.
50
What is one of the most notable benefits of using cells in bioprocesses?
Amazing diversity of products (e.g., proteins, enzymes, drugs).
51
How can cells be altered to improve bioprocessing?
They can be genetically modified to increase product diversity.
52
What role do enzymes play in bioprocessing?
They act as specific catalysts with high catalytic power.
53
What is traditional bioprocessing?
A method that uses cell cultures to produce products — the cell acts as a factory.
54
Give examples of products from traditional bioprocessing.
- Ethanol - Antibiotics - Vaccines / viruses - Recombinant therapeutic proteins (e.g., monoclonal antibodies)
55
What is stem cell bioprocessing?
A type of bioprocessing where the cells themselves are the final product.
56
What are key applications of stem cell bioprocessing?
- Banking and drug screening programs - Stem cell therapies (potential to cure diseases, not just treat symptoms)
57
How does stem cell bioprocessing differ from traditional bioprocessing?
In traditional bioprocessing, cells produce a product; in stem cell bioprocessing, the cells are the product.
58
What is the first step in a general bioprocess?
A single cryovial of cells is taken from the working cell bank (WCB).
59
What are the main stages of upstream processing?
- Media preparation - Cell thawing and inoculum expansion - Bioreactor scale-up (from 50L to 20,000L)
60
What occurs during downstream processing?
Product separation, purification, characterisation, and formulation.
61
What is the role of quality control (QC) in bioprocessing?
To ensure product purity, yield, and consistency at various stages.
62
What are unit operations in bioprocessing?
Steps that change or separate components during the process.
63
Name five examples of unit operations in bioprocessing.
- Centrifugation - Chromatography - Filtration - Evaporation - Distillation
64
Why are unit operations repeated in bioprocesses?
To achieve consistent separation, purification, or transformation.
65
What are the first steps in bioprocess development?
Engineer or isolate the cells and optimise growth/production conditions.
66
What are the key focuses during process development?
- Expanding the cells - Developing purification protocols - Formulation strategies
67
What concept ensures quality at every step in bioprocessing?
Quality by Design (QbD) — integrates product, process, and performance design.
68
What 3 criteria must a biotherapeutic meet to be successful?
1. Clinically effective 2. Approvable by regulatory authorities 3. Commercially viable
69
Give 3 examples of biotherapeutic technologies.
1. Recombinant protein technologies (e.g., monoclonal antibodies) 2. Cell and gene therapies 3. Viral vaccines
70
What are the 5 main steps in the production of recombinant proteins?

73
Why does quality matter in bioprocessing?
Because poor-quality products can harm or kill consumers, and regulatory compliance is essential (e.g., FDA GMP standards).
74
