CSTR

CSTR !?!?


In case you don't know what's CSTR mean,
here it stands for Continuous Stirred Tank Reactor ! 
It is a common ideal reactor used in fermentation process.
CSTR run at a steady state with continuous flow of reactants and products.
The feed assumes a uniform composition throughout the reactor while exit stream has the same composition as in the tank.
CSTR give some advantages, for example: continuous operation, good control of temperature and it is kinda easy to operate or construct.


So what had we done during the workshop? 


Day 1
Introduction of Infors
Concise guide into Fermentation
Preparation of the fermentor (Demo)
Preparation of seed culture


Day 2
Calibration of the O2 probes
Steps for inoculation
Starting of IRIS software
Maintainence procedures and "Do's and Don'ts"
Software lectures
Sampling and parameter optimization


Day 3
Video of fermentors in industry
Viewing of 15 liter fermentor
Cleaning and emptying the fermentation vessel




The fermentation carried out by us is basically the same as the diagram shown below:

and the fermentor we used is as belows:

Minifors 

Some basic understanding of Minifors:

Available in both bacterial and cell culture versions, Minifors is supplied as a package with everything necessary to take the next step in capacity and control from shake flasks or spinners. For example, the basic bacterial Minifors gives you pH control, feeding, sampling and software for data-logging straight out of the box. 

The control system provides all the necessary parameters for a wide range of applications and the operating is based on the instrumentation for our incubator shakers, so making it easy to use.
