Biological sample: The BIOKIN-4 experiment investigates the bacteria Xanthobacter autotrophicus.

BIOKIN-4 experiment: An aerobic liquid culture of Xanthobacter autotrophicus is required by the scientists to assess Xanthobacter autotrophicus growth kinetics on a model membrane bioreactor to be used in a Biological Air Filter (BAF).

Hardware performance: The EU is designed to allow a liquid aerobic culture of Xanthobacter autotrophicus. Bacteria cells are activated, incubated and fixed in a fully autonomous way. The EU can perform two experiments at the same time. Outcomes are validated by comparison with two reference CC. Different bacteria strains, aerobic or anaerobic, can fit into the EU.
