What bioreactor means?
Bioreactor is defined as a vessel that carries out a biological reaction and is used to culture aerobic cells for conducting cellular or enzymatic immobilization.
How are bioreactors and fermentors different?
The key difference between bioreactor and fermentor is the type of biochemical reaction that takes place inside the closed vessels. A bioreactor facilitates all types of biochemical reactions but, a fermentor facilitates fermentation only.
What are bioreactors explain it with example?
An example of a continuous bioreactor is the chemostat. Organisms growing in bioreactors may be submerged in liquid medium or may be attached to the surface of a solid medium. Large scale immobilized cell bioreactors are: moving media, also known as moving bed biofilm reactor (MBBR) packed bed.
How does bioreactor work cell culture?
During the bioprocess, the bioreactor feeds a sterile gas mixture such as air into the culture medium. Constant stirring not only distributes the nutrients – it also reduces the size of the gas bubbles that arise in the culture vessel, thus efficiently releasing oxygen into the nutrient solution.
Who discovered the bioreactor?
Wolf, Schwarz, and Trinh won NASA “Inventor of the Year” honors for their innovation. In 1990, Anderson and Schwarz licensed patents for the rotating wall bioreactor technology and founded Synthecon Inc. in Houston, Texas, to commercialize the device.
What is reactor and bioreactor?
A bioreactor can be defined as an engineered system, deployed to facilitate the growth of biological mass through the transformation or degradation of material fed to the reactor.
What is bioreactor and its types?
There are many different types of bioreactors including: stirred-tank, rocker, air lift and fixed-bed. Stirred-tank bioreactors are equipped with an impeller for homogenizing culture media and a sparger for delivering oxygen to the cells. Stirred-tank reactors (STRs) are the most widely-used bioreactors.
What is the medical definition of a bioreactor?
Medical Definition of bioreactor. : a device or apparatus in which living organisms and especially bacteria synthesize useful substances (as interferon) or break down harmful ones (as in sewage)
What is the definition of communism in economics?
Full Article Communism, political and economic doctrine that aims to replace private property and a profit-based economy with public ownership and communal control of at least the major means of production (e.g., mines, mills, and factories) and the natural resources of a society.
What kind of government do they have in communism?
Communism is a type of government as well as an economic system (a way of creating and sharing wealth). In a Communist system, individual people do not own land, factories, or machinery.
What kind of supplies are used in a bioreactor?
For Novavax, those supplies included 2,000-liter bioreactor bags, used to culture cells; depth filters for the purification process; and the growth media, which is used to feed the cells.
