Which of the following is a fundamental basis for classifying bioreactors?
B
Type of biological organism
C
Mode of operation and mixing method
Analysis & Theory
Bioreactors are classified based on operation (batch, continuous) and mixing (mechanical, pneumatic, etc.).
Which of the following is a mechanically agitated bioreactor?
Analysis & Theory
A stirred tank reactor uses mechanical agitation to mix the contents.
Photobioreactors are specifically designed for:
C
Photosynthetic microorganisms
Analysis & Theory
Photobioreactors provide light, making them suitable for microalgae and other photosynthetic organisms.
In which type of bioreactor are solid supports used to immobilize cells?
Analysis & Theory
Packed bed reactors allow immobilization of cells or enzymes on solid media.
Which bioreactor is ideal for cultivating shear-sensitive cells?
Analysis & Theory
Airlift reactors reduce mechanical shear, protecting delicate cells like mammalian or plant cells.
What type of bioreactor integrates membrane filtration with biological processes?
Analysis & Theory
Membrane bioreactors combine biological treatment with membrane separation.
Which classification of bioreactor is based on process operation mode?
A
Batch, Fed-batch, Continuous
B
Pneumatic and Non-pneumatic
D
Horizontal and Vertical
Analysis & Theory
Operation mode classifies bioreactors as batch, fed-batch, or continuous systems.
A bubble column reactor falls under which bioreactor type?
Analysis & Theory
Bubble column reactors use air/gas for agitation, making them pneumatically agitated.
Which bioreactor is best suited for continuous solid-state fermentation?
Analysis & Theory
Packed bed bioreactors are used in solid-state fermentation with immobilized cultures.
Which of the following is NOT a typical classification of bioreactors?
D
Based on mode of operation
Analysis & Theory
Bioreactors are not classified based on pH, but rather on factors like agitation and operation mode.
