Two basic type of fermenter 1) A glass vessel with a round or flat bottom and a top flanged carrying plate. (sterilized by autoclaving) 2) A glass. Bioreactors can be classified according to various different criteria Type and form of biocatalyst: free cells in submerged cultures; carried bound or immobilized. This article throws light upon the six types of bioreactors used in bioprocess technology. The six types are: (1) Continuous Stirred Tank Bioreactors (2) Bubble.

A liquid fluidized bed may be sparged with air or some other gas to produce a gas-liquid-solid types of fermenters bed. If the solid particles are too light,they can be artificially weighted. The min fluidization velocity i.

The types of fermenters is recirculated through packed bed by pump and oxygenated by input of air in a secondary vessel. The flow maybe upward or downward but down flow under the gravity is normal. Typically the culture density of algae produced is 10 to 20 times greater than bag culture in which algaeculture is done in bags — and can be even types of fermenters.

Better control of gas transfer.

Bio-Resource: Different Types of Fermentors / Bioreactors

Reduction in evaporation of growth medium. Better protection from outside contamination. Space saving — Can be mounted vertically, horizontally or at an angle, indoors or outdoors.


Reduced Fouling — Recently available tube self cleaning mechanisms can dramatically reduce fouling. Membrane Bioreactor Membrane bioreactors successfully applied to various microbial bioconversions such as alcoholic fermentation, solvents, types of fermenters acid production, waste water treatment, etc.

However, these bioreactors are preferred for bioprocessing technology involving product-inhibited reactions.

Fermentor (Bioreactor): History, Design and Its Construction

The packed bed bioreactors do not allow accumulation of the products to any significant extent. These are the bioreactors specialised for fermentation that can be carried out either by exposing to sunlight or artificial illumination.

Since artificial illumination is expensive, only the outdoor photo-bioreactors types of fermenters preferred.

Certain important compounds are produced by employing photo-bioreactors e.

The different types of photo-bioreactors are depicted in Fig. They are made up of glass or more commonly transparent plastic.

Types of fermenters.

The array of tubes or flat panels constitute light receiving systems solar receivers. The culture can be circulated through the solar receivers by methods such as using centrifugal pumps or airlift pumps.

types of fermenters It is essential that the cells are in continuous circulation without forming sediments. Further adequate penetration of sunlight should be maintained.

The tubes should also be cooled to prevent rise in temperature.

Fermentor (Bioreactor): History, Design and Its Construction

types of fermenters Microalgae and cyanobacteria are normally used. The organisms grow during day light while the products are produced during night.

The smaller particle size facilitates higher mass transfer rates and better mixing.

The volumetric productivity attained in FBBs is usually higher than in stirred tank and packed bed bioreactors. There are several successful examples of using FBBs in types of fermenters development. The use of packed bed reactors gained importance after the potential of whole cell immobilization technique has been demonstrated.

The immobilized biocatalyst is packed in the column and fed with nutrients either from top or from bottom. One of the disadvantages of packed beds is the changed flow characteristic due types of fermenters alterations in the bed porosity during operation.
