Stable storage of microorganisms
Microorganisms (bacteria, yeast, fungi, algae etc.) can lose their desired production properties during cultivation. This can be prevented by keeping the microorganism under specific conditions where (genetic) changes are no longer possible. The conservation and storage conditions depend on the microbial species itself, the desired product and the degree of strain improvement.
Other important parameters are the way the organism is cultivated before conservation takes place and the way in which the growth is triggered after the conservation. The quality of the stored cell material is monitored for a certain period of time.
