Oxygen transfer is usually helped by agitation, which is also needed to mix nutrients and to keep the fermentation homogeneous. The reaction kinetics involved in biochemical operations is comparatively difficult to obtain than the chemical reaction kinetics.

Thus,Equations 15 and 16 are the basic equations which are used for the modelling of any bioreactor. Articles needing additional references from October All articles needing additional references Wikipedia articles needing reorganization from April Articles with multiple maintenance issues Wikipedia articles with style issues from July All articles with style issues Commons category link is on Wikidata Wikipedia articles with NDL identifiers.

Till now, the industries associated with biotechnology have been lagged behind other industries in implementing control over the process and optimization strategies.

Bioreactor – Wikipedia

Since we have assumed that the feed stream does not contain any biomass i. In some of these systems, a chemically inert medium with very high surface area is airift as a substrate for the growth of biological film.

In biochemical engineering, yield is defined as the ratio of mass or moles of product formed to the mass or moles of the reactants consumed.

In other systems aerators supply oxygen to the sewage and biota to create activated sludge in which the biological component is freely mixed in the liquor in “flocs”.


Particularly exothermic fermentations may require the use of external heat exchangers. Often content unacceptable to Wikipedia may not be acceptable on Wikiversity either; facilitate the copying of this article by listing it on Wikiversity: This page was last edited on 30 Decemberat In bioreactors in which the goal is to grow cells or tissues for experimental or therapeutic purposes, the design is significantly different from industrial bioreactors.

Dividing both sides of the above equation by V, we obtain. Suspension bioreactors can use a wider variety of organisms, since special attachment surfaces are not needed, biorreactlres can operate at much larger scale than immobilized cultures.

Current achievements in the production of complex biopharmaceuticals with moss bioreactor. However, in a continuously operated process the organisms airljft be removed from the reactor with the effluent.


In biochemical operations, the cell kinetics is used for the unstructured biorreactorss where balanced growth condition is assumed. Learn how and when to remove these template messages. Bioreactor design is a relatively complex engineering task, which is studied in the discipline of biochemical engineering.

It is first converted to more suitable form for processing. The temperature of the fermentation medium is maintained by a cooling jacket, coils, or biordeactores.

A main drawback in biotechnological process control is the problem to measure key physical and biochemical parameters. Interior surfaces are typically made of stainless steel for easy cleaning and sanitation.

These bioreactors are commonly cylindrical, ranging in size from litres to cubic metres, and are often made of stainless steel. This step is mainly consists of three operations namely, production of biomassmetabolize biosynthesis and biotransformation.

Processing of biological materials using biological agents such as cells, enzymes or antibodies are the major pillars of biochemical engineering.

Many cells and tissues, especially mammalian ones, must have a surface or other structural support in order to grow, airift agitated environments are often destructive to these cell types and tissues. Please help improve this article by adding citations to reliable sources.

Biology portal Biotechnology portal. Submerged cultures may be suspended or immobilized.

Consequently, risk of contamination with other organisms like bacteria or fungi is lower in photobioreactors when compared to bioreactors for heterotroph organisms. Arilift may also refer to a device or system designed to grow cells or tissues in the context biorrwactores cell culture. See Wikipedia’s guide to writing better articles for suggestions.

A bioprocess is composed mainly of three stages — upstream processing, bioreaction, and downstream processing — to convert raw material to finished product.

Bioreactors are generally used in those industries which are concerned with food, beverages and pharmaceuticals. This article has multiple issues. In other projects Wikimedia Commons.

This article needs additional citations for verification. Immobilization is a general term biorreacttores a wide variety of cell or particle attachment or entrapment. Mathematical models act as an important tool in various bio-reactor applications including wastewater treatment. Conventional sewage treatment utilises bioreactors to undertake the main purification processes.
