Engineering:Auxostat

From HandWiki
Auxostat example

An auxostat is a continuous culture device which, while in operation, uses feedback from a measurement taken on the growth chamber to control the media flow rate, maintaining the measurement at a constant.

Auxo was the Ancient Greece goddess of spring growth, and represents nutrients as a prefix. However, the most typical auxostats are pH-auxostats,[1] with feedback between the growth rate and a pH meter.

Other auxostats may measure oxygen tension, ethanol concentrations, and sugar concentrations [2]
