Abstract

In view of long haul space exploration missions, the development of regenerative life support systems is a condition sine qua non to increase the crew autonomy and decrease the cost associated to the mass embarked. Therefore, in the late 80's, the European Space Agency initiated the MELiSSA project (Micro-Ecological Life Support System Alternative). MELISSA has been conceived as a micro-organisms and higher plant process enabling high recycling efficiency. Nevertheless, the organisms inhabiting the the MELISSA system need to perform their tasks as optimally as possible (Fig. 1). A number of stresses such as temperature variation, water deprivation, oxidative stress, UV and ionizing radiations, light variation, supernatant of the previous compartment, genomic evolution during long-time culturing and gene transfer can indeed affect the capabilities of the micro-organisms as well as the efficiency of the whole bioregenerative loop. Thus, the detection of functional and genetic instability due to stress in all bioreactors of the MELiSSA loop is considered to be of primordial importance. In this paper a global approach is put forward to analyse the stress response of R. rubrum ATCC25903, using whole cell flow cytometry analysis, mass spectrometry analysis and microarray gene expression profiling.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
