Auxostat

Auxostat

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 Greek goddess of spring growth, and as a prefix represents nutrients. However, the most typical auxostats are pH-auxostats cite journal |title=The pH-auxostat as a tool for studying microbial dynamics in continuous fermentation |author=Larsson G, Enfors S O, |journal=Biotechnology and Bioengineering |volume=36 |issue=3 |pages=224–232 |year=1990 |doi=10.1002/bit.260360303>] , with feedback between the growth rate and a pH meter.

Other auxostats may measure oxygen tension, ethanol concentrations, and sugar concentrations cite journal |author=Gostomski P, Muhlemann M, Lin YH, Mormino R, Bungay H |journal=Journal of Biotechnology |year=1994 |volume=37 |issue=2 |pages=167–177 |title=Auxostats for continuous culture research |doi=10.1016/0168-1656(94)90008-6]
