Reactor Scale:
|
|
|
| |
Your choices are...
|
|
|
| |
Laboratory
|
|
The laboratory scale is used for small-scale experiments of kinetics and yield studies. They are primarily shake flasks and small bioreactors. This scale is used to complete a preliminary economic evaluation of experiments.
|
| |
Pilot
|
|
Pilot scale reactors are usually in the range of 100 to 1,000 liters and are utilized in kinetic and mass transfer studies. They are used for economic evaluations, scale-up studies and downstream processing.
|
| |
Production
|
|
May also be called industrial scale. These reactors are used for commercial production applications in the range of 1,000 to 1,000,000 liters. Their uses include commissioning, troubleshooting, improvement and optimization.

Reactor Design:
|
|
|
| |
Your choices are...
|
|
|
| |
Airlift Reactor
|
|
These reactors are similar to bubble column reactors, but differ by the fact that they contain a draft tube. The draft tube is typically an inner tube, which improves circulation and oxygen transfer and equalizes shear forces in the reactor.
|
| |
Bubble Column Reactor
|
|
These are tall reactors, which use air alone to mix the contents.
|
| |
Flocculated Cell Reactor
|
|
Flocculated cell reactors retain cells by allowing them to flocculate. These reactors are used mainly in wastewater treatment.
|
| |
Fluidized Bed Reactor
|
|
In fluidized bed reactors, cells are "immobilized" small particles, which move with the fluid. The small particles create a large surface area for cells to stick to and enable a high rate of transfer of oxygen and nutrients to the cells.
|
| |
Packed Bed Reactor
|
|
In packed bed reactors, cells are immobilized on large particles. These particles do not move with the liquid. Packed bed reactors are simple to construct and operate but can suffer from blockages and from poor oxygen transfer.
|
| |
Stirred Tank Reactor
|
|
In these reactors, mechanical stirrers (using impellers) are used to mix the reactor to distribute heat and materials (such as oxygen and substrates).
|
| |
Other
|
|
Other unlisted or proprietary reactor type.

Reactor Operation:
|
|
|
| |
Your choices are...
|
|
|
| |
Batch
|
|
Batch reactors are simplest type of reactor operation. In this mode, the reactor is filled with medium and the fermentation is allowed to proceed. When the fermentation has finished the contents are emptied for downstream processing. The reactor is then cleaned, re-filled, re-inoculated and the fermentation process starts again.
|
| |
Continuous
|
|
With continuous reactors, fresh media is continuously added and bioreactor fluid is continuously removed. As a result, cells continuously receive fresh medium and products and waste products and cells are continuously removed for processing. The reactor can thus be operated for long periods of time without having to be shut down. Continuous reactors can be many times more productive than batch reactors. This is partly due to the fact that the reactor does not have to be shut down as regularly and also due to the fact that the growth rate of the bacteria in the reactor can be more easily controlled and optimized. In addition, cells can also be immobilized in continuous reactors, to prevent their removal and thus further increase the productivity of these reactors.
|
| |
Fed-batch
|
|
The fed batch reactor is the most common type of reactor used in industry. In this reactor, fresh media is continuous or sometimes periodically added to the bioreactor but unlike a continuous reactor, there is no continuous removal. The fermenter is emptied or partially emptied when reactor is full or fermentation is finished. As with the continuous reactor, it is possible to achieve high productivities due to the fact that controlling the flow rate of the feed entering the reactor can optimize the growth rate of the cells.

Parameters Controlled:
|
|
|
| |
Your choices are...
|
|
|
| |
pH
|
|
The reactor can control the pH level of the sample.
|

Temperature
|
|
The reactor can control the temperature of its contents.
|
| |
Dissolved Oxygen
|
|

|
| |
Foam
|
|
Foaming is the persistence of bubbles caused by fermenter aeration and agitation. Foam is very important part of the fermentation process. Severe foaming in a fermentation vessel may cause contamination or loss of material, either of which will decrease yields and invalidate experimental data.
