Exemplary flashcards for Biotechnology - Exam Preparation at the Hochschule Bonn-Rhein-Sieg on StudySmarter:

Biotechnology - Exam Preparation

Please list at least three advantages of biotechnology versus chemical synthesis.
- Complex molecules, like proteins, cannot be produced by chemical means
- Bioconversions give higher yields
- Biological systems work under moderate conditions (room temperature, neutral pH etc.)
- Great specificity of a catalytic reaction (e.g. exclusive production of an isomeric compound)

Biotechnology - Exam Preparation

Please name three methods how to immobilize enzymes in fixed-bed reactors?
- Binding of cells or enzyme to carrier
- Inclusion of cells within carrier material
- Microencapsulation of enzymes or cells

Biotechnology - Exam Preparation

Please name two typical characteristics of cheese types produced with propionibacteria?
Swiss cheese and Emmentaler cheese are produced using propionibacteria (e.g. Propionibacterium freundenreichii spp. shermanii)

Characteristics:
- Propionic acid formation contributes to flavour
- CO production causes big holes in cheese

Biotechnology - Exam Preparation

Which species is industrially used for citric acid production?
Aspergillus niger

Biotechnology - Exam Preparation

What is selective breeding?
Selective breeding is the breeding of plants and animals in a way that is produced desirable traits 

Biotechnology - Exam Preparation

Name the three main branches of traditional biotechnology.
- Plant selection
- Animal domestication and breeding
- Food modification (e.g. beer/wine brewing)

Biotechnology - Exam Preparation

Why was food modification so important in former times?
Food modification was necessary to preserve food for times of shortage as foods such as cheese spoil much slower than milk

Biotechnology - Exam Preparation

What is biotechnology?
Biotechnology is defined as using an organism or product of an organism to the benefit of humanity

Biotechnology - Exam Preparation

Give an example for a biotechnological procedure which has more advantages compared to chemical synthesis.
Haber-Bosch procedure
-> production of ammonia
Chemical conversion: requires 200-300 atm and 300-600°C
Biotechnological approach: uses nitrogenase, can be done at RT, no added pressure needed

Biotechnology - Exam Preparation

What are the main aims of bioprocess engineering?
- Minimize investment and cost
- Maximining profitability
- Ensuring simple, reliable and safe working conditions

Biotechnology - Exam Preparation

Name the most important factors for the development of a bioreactor.
- efficient mixing (good mass transfer)
- heating/cooling (constant temperature, no fluctuation)
- aeration (according to microbe)
- minimize foam generation
- regulate mechanical stress
- closed system (prevent contamination and loss of product)
- constant volume (prevent leakage/evaporation)
- oxygen level (above critical level)
- monitor and control environmental parameters
- pH control (especially for acid producing microbes)

Biotechnology - Exam Preparation

Give a general definition of bioreactors/stirred tank reactors.
Bioreactors/stirred tank reactors (fermenters) can range from 1L to more than 500,000L.

- have stirrers inside to mix air and nutrients with ports to allow insertion of sensors and pumps for added flexibility
- can harbour batch cultures, fed-batch cultures and continous cultures
