Where are bioreactors used?
Bioreactors are used in the food, medical, pharmaceutical and cosmetics industries. Each of these produces certain types of biomolecules, depending on the use of the final product. Some are also produced in the form of complex products, while others remain molecules..
A bioreactor is a complex system, designed to produce compounds and substances with the help of cells or whole organisms. These compounds are then used as finished products, such as beer, or are treated in additional processing steps in order to get an isolated compound such as vaccines or proteins.
A bioreactor is a vessel in which enzymatic or cellular reaction converts substrates to products, byproducts, and wastes, or eliminates water-soluble organics from wastewater aerobically to CO2, H2O, and other gaseous forms anaerobically to CH4 or N2.
How Does A Bioreactor Work? By providing a controlled environment, a bioreactor allows living organisms to grow, reproduce, and perform metabolic processes. This controlled environment is achieved through the regulation of various factors, including temperature, pH, oxygen concentration, and nutrient supply.
The stirred-tank bioreactor is one of the most commonly used types, and is used both for industrial applications and laboratory research.
Combining engineering and biology, bioreactors are able to replicate key features of organs and tissues and to provide cells with dynamic stimuli such as flow or mechanical and electrical cues.
For mammalian cells, plant cells, insect cells, viruses cultivated on cells, our bioreactors are available with capacities ranging from 30 to 25,000 liters.
Shear sensitivity and slow growth rates necessitate special components and special reactor designs: Aeration strategies with gas-mixing stations, surface
Can bioreactors be used for lung engineering?
Bioreactors for lung engineering must leverage aspects of both developmental and postnatal physiology to drive repopulation of decellularized scaffolds and generate functional organs from existing building blocks.

Since the ultimate aim of a bioreactor is to create a biological product, the engineering parameters, ..
Anaerobic membrane bioreactor or AnMBR is the name of a technology utilized in wastewater treatment. It is a new technology in membrane filtration for biomass retention. AnMBR works by using a membrane bioreactor (MBR). The sewage is filtered and separated leaving the effluent and sludge apart. This sludge is treated anaerobically by mesophilic bacteria which release methane as a byproduct. The biogas can later be combusted to generate heat or electricity. AnMBR is considered to be a sustainable alternative for sewage treatment because the energy that can be generated by methane combustion can exceed the energy required for maintaining the process.
Bioengineering bioreactor
System that supports a biologically active environment
A bioreactor refers to any manufactured device or system that supports a biologically active environment. In one case, a bioreactor is a vessel in which a chemical process is carried out which involves organisms or biochemically active substances derived from such organisms. This process can either be aerobic or anaerobic. These bioreactors are commonly cylindrical, ranging in size from litres to cubic metres, and are often made of stainless steel.
It may also refer to a device or system designed to grow cells or tissues in the context of cell culture. These devices are being developed for use in tissue engineering or biochemical/bioprocess engineering.
Substrate inhibition in bioreactors occurs when the concentration of substrate exceeds the optimal parameters and reduces the growth rate of the cells within the bioreactor. This is often confused with substrate limitation, which describes environments in which cell growth is limited due to of low substrate. Limited conditions can be modeled with the Monod equation; however, the Monod equation is no longer suitable in substrate inhibiting conditions. A Monod deviation, such as the Haldane (Andrew) equation, is more suitable for substrate inhibiting conditions. These cell growth models are analogous to equations that describe enzyme kinetics, although, unlike enzyme kinetics parameters, cell growth parameters are generally empirically estimated.
