Biological sample: The BASE B experiment focuses on three anaerobic bacteria strains, i.e. Cupriavidus metallidurans CH34 (ATCC43123); Bacillus turingiensis sv. kurstaki HD73 (ATCC35866); Pseudomonas putida KT2440.
BASE-B experiment: BASE-B studies the effects of space flight conditions on the behaviour of bacteria. The experiment aims to assess how bacteria cope with and adapt to the different space flight environmental parameters (e.g. microgravity, cosmic radiation, space electromagnetism, space vibrations).
The fluidic concept carries out the BASE-B experimental protocol which relies on three main steps, i.e. bacteria activation, bacteria incubation, bacteria fixation.
Hardware performance: The EU is designed to incubate anaerobic bacteria in liquid media. Bacteria cells are activated, incubated and fixed in a fully autonomous way. The expandable CC makes possible a protocol with different volumes. The EU can perform two experiments and two reference experiments at the same time. Outcomes are validated by
comparison.
