Bioreactors; Device, Vessel, or Tank That Supports a Biologically Active Environment
Bioreactors are defined as a manufacturing device or vessel
in which biological reactions are performed and are used in the production of
wide range of biological products. Bioreactors are tanks/vessels in which cells
or cell-free enzymes transform raw materials into biochemical products and/or
less undesirable by-products. Bioreactors are designed to create a biologically
active environment. The system can house organisms or biochemically active
substances. It can be used to perform chemical processes.
Bioreactors are cylindrically shaped, and range in different
sizes from liters to cubic meters. They are commonly 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.
Bioreactors
are commonly used to create biofuels. Specifically, algae bioreactors can be
used to produce fuels such as bioethanol and biodiesel, to generate animal
feed, or reduce pollutants such as CO2 and NOx in flue gases of power plants.
In the food industry, bioreactors widely used to produce alcoholic beverages,
yogurt, vinegar, enzymes, aroma compounds, other lactic beverages, yeast
biomass, and pigments, which extends their usefulness to coffee fermentation.
They are mainly used for fermentation and are referred to as fermenters.
A fermentor is basically the type of bioreactor, used
specifically for fermentation. Bioreactors
are also used in industrial processes to produce pharmaceuticals, vaccines,
or antibodies. Batch bioreactors are one of the most common types of bioreactor
configurations used in the pharma industry. Bioreactor systems can meet the
ever-changing needs of all stages of biotechnology and pharmaceutical science
and suitable for to produce therapeutics. Bioreactors are often used in the
food, medical, pharmaceutical and cosmetics industries.
Many microorganisms and their natural communities require
special environments to grow. In Germany, an automated bioreactor is being developed
that can be used to cultivate even those microbes that make very special
demands on their environment.
