Control and reaction monitoring<br />
in fermentation processes<br />
Microorganisms can be used in biological<br />
reactors, e.g. for the production of enzymes<br />
or in the preparation of drugs. However, this<br />
involves extensive measurement and control<br />
equipment to maintain optimal conditions<br />
for growth of the microorganisms used<br />
(e.g. baker's yeast).<br />
A relatively simple and completely safe<br />
example of this is the production of ethanol<br />
from baker's yeast (Saccharomyces cerevisiae).<br />
This is a biochemical means of preparing<br />
alcohol from sugar using yeast cells. The process<br />
is controlled and monitored by the CASSY-S<br />
module and the software CASSY Lab.<br />
