Summary:

The concept for the "Biological Air Filter" (BAF) is based onto the property of certain selected microorganisms for the complete oxidation to water, carbon dioxide and salts, of gaseous contaminants.The EXEMSI manned space mission simulation campaign offered a good opportunity for testing the performances of an experimental BAF on a real confined atmosphere.Major obtained results are:Among the degraded contaminants, elimination yield for the identified contaminants ranges around 10 to 40% for methane, 50 to 90% for acetone, 80 to 99% for isopropanol and above 99.9% for toluene. Computer modelling show that such a methane conversion efficiency (obtained for a single passage through a BAF) is sufficient to maintain the methane concentration in a space cabin below the SMAC value.As a side result, the trace contamination regime in EXEMSI was experienced being characterised by very sharp and large changes in concentrations; a further conclusion regarding confinement experiments is hence the need for continuous or integrating monitoring of trace contaminants
