PURPOSE:
Development of biological safety assurance techniques
for spacecraft based on the investigation of initial
stages of colonization of surfaces of structural materials
of habitation modules and SC external surfaces by
various microorganisms.
OBJECTIVE:
Investigation of the initial stages of colonization
of surfaces of structural materials by microorganisms
under ISS crew confined habitation environment conditions.
EXPERIMENT RESULTS:
Microflora samples (20 samples) in Biosamples Kit
taken from surfaces of the structural materials of
the ISS RS pressurized compartments.
EXPECTED RESULTS:
Acquisition of new integrated data on colonization
dynamics for various material surfaces, composition
and structure of biological layers, destructive properties
of their microorganisms, their sensitivity to various
biocydes, that will allow to choose more advanced
approaches for inhibition of harmful activity of destructive
microorganisms, and purposefully proceed to development
of effective methods of protecting SC structural and
decorative materials against biological corrosion
and biological damages.
