Mathematical models act as an important tool in various bio-reactor applications including wastewater treatment. It may also refer to a device or system designed to grow cells or tissues in the context of cell culture.
This article has multiple issues.
Sparger — In aerobic cultivation process, the purpose of the sparger is to supply adequate oxygen to the growing cells. Particularly exothermic fermentations may require the use of external heat exchangers. Organisms growing in bioreactors may be submerged in liquid medium or may be attached to the surface of a solid medium.
The environmental conditions inside the bioreactor, such as akrlift, nutrient concentrations, pH, and dissolved gases especially oxygen for aerobic fermentations affect the growth and productivity of the organisms.
A main drawback in biotechnological process control is the problem to measure key physical and biochemical parameters. If the page can be re-written into an encyclopedic article, please do so and remove this message. Photobioreactors are used to grow small phototrophic organisms such as cyanobacteriaalgaeor moss plants.
The yield Y of product P with respect to reactant A is defined as:. The biosolids can be collected for further processing, or dried and used as fertilizer.
NASA has developed a new type of bioreactor that artificially grows tissue in cell cultures. Applications of biochemical engineering cover major fields of civilization such as agriculture, food and healthcare, resource recovery and fine chemicals.
In practice, bioreactors are often pressurized; this increases the solubility of oxygen in water.
These devices are being developed for use in tissue engineering or biochemical engineering. It is first converted to more suitable form for processing.
The reaction kinetics involved in biochemical operations is comparatively difficult to obtain than the chemical reaction kinetics. Bioreactor design is a relatively complex engineering task, which is studied in the discipline of biochemical engineering. Views Read Edit View history.

Bioreactor – Wikipedia
These models are useful for planning efficient process control strategies and predicting the future plant performance. Since oxygen is relatively insoluble in water the basis of nearly all fermentation mediaair or purified oxygen must be added continuously.
This page is a candidate to be copied to Wikiversity using the Import process. After upstream processing step, the resulting feed is transferred to one or more Bioreaction stages.

An example of a continuous bioreactor is the chemostat. Please help by editing the article to make improvements to the overall structure. This article may be in need of reorganization to comply with Wikipedia’s layout guidelines. April Learn how and when to remove this template message.

This process can either be aerobic or anaerobic. This article needs additional citations for verification.
Heat transfer is an important part of bioreactor design; small vessels can be cooled with a cooling jacket, but larger vessels may require coils or an external heat exchanger. In biochemical operations, the cell kinetics is used for the unstructured models where balanced growth condition is assumed.
