Online monitoring applying the anaerobic respiratory monitoring system reveals iron(II) limitation in YTF medium for .

Online monitoring of microbial cultures is an effective approach for studying both aerobic and anaerobic microorganisms. Especially in small-scale cultivations, several parallel online monitored experiments can generate a detailed understanding of the cultivation, compared to a situation where a few data points are generated from time course sampling and offline analysis. However, the availability of small-scale online monitoring devices for acetogenic organisms is limited.
