WHAT IS BIOREACTOR
A bioreactor is a device or system that provides
a controlled environment for the cultivation of
living cells, microorganisms, or biological
processes. It facilitates the growth,
metabolism, and production of desired products
by maintaining optimal conditions such as
temperature, pH, nutrient supply, and oxygen
levels.

STIRRED TANK BIOREACTOR
Definition A common and versatile bioreactor
design featuring an agitator to ensure proper
mixing and oxygen transfer.
Key features Agitation system (impeller or
stirrer) Sparger for oxygenation Temperature
control pH control Applications Microbial
fermentation, cell culture, enzyme production.
5
AIR-LIFT BIOREACTOR
Definition A bioreactor that relies on gas
sparging to create circulation and mixing. Key
features Gas inlet for sparging Draft tube for
gas-liquid separation and circulation Reduced
shear stress on cells Applications Animal cell
culture, plant cell culture, microbial
fermentation.
6
PACKED BED BIOREACTOR
Definition A bioreactor containing a packed bed
of solid support material for immobilized cells
or enzymes.
Key features Porous support material for cell or
enzyme attachment Perfusion or continuous flow
operation Enhanced mass transfer and
stability Applications Enzyme production,
wastewater treatment, bioconversion processes.
7
MEMBRANE BIOREACTOR
Definition A bioreactor that incorporates a
semipermeable membrane for separation and
retention of biomass or products.
Key features Membrane for filtration and
retention of cells or particles Improved product
separation and concentration Reduced risk of
contamination Applications Bioprocessing,
biodegradation, water treatment.
8
FLUIDIZED BED BIOREACTOR
Definition A bioreactor where solid particles
are suspended and fluidized by an upward flow of
liquid or gas.
Key features Fluidization of solid particles for
enhanced mixing and mass transfer High surface
area-to-volume ratio Uniform distribution of
nutrients and gases Applications Biocatalysis,
enzyme immobilization, waste treatment.
9
PHOTOBIOREACTOR
Definition A bioreactor that utilizes light as
an energy source for photosynthetic
organisms Key features Transparent or
translucent vessel for light penetration Light
sources or natural sunlight Efficient conversion
of light energy into biomass Applications Algae
cultivation, photosynthetic microbial
production, biofuel production
