    Beyond Chloride Brines: Variable Metabolomic Responses in the Anaerobic Organism Yersinia intermedia MASE-LG-1 to NaCl and MgSO4 at Identical Water Activity 
    Schwendner, Petra; Bohmeier, Maria; Rettberg, Petra; Beblo-Vranesevic, Kristina; Gaboyer, Frédéric; Moissl-Eichinger, Christine; Perras, Alexandra K.; Vannier, Pauline; Marteinsson, Viggó; Garcia-Descalzo, Laura; Gómez, Felipe; Malki, Moustafa; Amils, Ricardo; Westall, Frances; Riedo, Andreas; Monaghan, Euan P.; Ehrenfreund, Pascale; Cabezas, Patricia; Walter, Nicolas; Cockell, Charles (Frontiers Media SA, 2018-02-27)
    Growth in sodium chloride (NaCl) is known to induce stress in non-halophilic microorganisms leading to effects on the microbial metabolism and cell structure. Microorganisms have evolved a number of adaptations, both structural and metabolic, to ...

    Microbial Markers Profile in Anaerobic Mars Analogue Environments Using the LDChip (Life Detector Chip) Antibody Microarray Core of the SOLID (Signs of Life Detector) Platform 
    García-Descalzo, Laura; Parro, Victorino; García-Villadangos, Miriam; Cockell, Charles S.; Moissl-Eichinger, Christine; Perras, Alex; Rettberg, Petra; Beblo-Vranesevic, Kristina; Bohmeier, Maria; Rabbow, Elke; Westall, Frances; Gaboyer, Frederik; Amils, Ricardo; Malki, Moustafa; Marteinsson, Viggó; Vannier, Pauline; Ehrenfreund, Pascale; Monaghan, Euan; Riedo, Andreas; Cabezas, Patricia; Walter, Nicolas; Gómez, Felipe Gómez (MDPI AG, 2019-09-18)
    One of the main objectives for astrobiology is to unravel and explore the habitability of environments beyond Earth, paying special attention to Mars. If the combined environmental stress factors on Mars are compatible with life or if they were less ...

    Microbial Metabolism of Amino Acids—Biologically Induced Removal of Glycine and the Resulting Fingerprint as a Potential Biosignature 
    Schwendner, Petra; Riedo, Andreas; Melton, Daniel J.; Horvath, Peter; Lindner, Robert; Ehrenfreund, Pascale; Beblo-Vranesevic, Kristina; Rettberg, Petra; Rabbow, Elke; Westall, Frances; Bashir, Alexandra; Moissl-Eichinger, Christine; Garcia-Descalzo, Laura; Gomez, Felipe; Amils, Ricardo; Marteinsson, Viggó Þór; Walter, Nicolas; Cockell, Charles S. (2022-04-04)
    The identification of reliable biomarkers, such as amino acids, is key for the search of extraterrestrial life. A large number of microorganisms metabolize, synthesize, take up and excrete amino acids as part of the amino acid metabolism during aerobic ...

    The responses of an anaerobic microorganism, Yersinia intermedia MASE-LG-1 to individual and combined simulated Martian stresses 
    Beblo-Vranesevic, Kristina; Bohmeier, Maria; Perras, Alexandra K.; Schwendner, Petra; Rabbow, Elke; Moissl-Eichinger, Christine; Cockell, Charles S.; Pukall, Rüdiger; Vannier, Pauline; Marteinsson, Viggó; Monaghan, Euan P.; Ehrenfreund, Pascale; Garcia-Descalzo, Laura; Gómez, Felipe; Malki, Moustafa; Amils, Ricardo; Gaboyer, Frédéric; Westall, Frances; Cabezas, Patricia; Walter, Nicolas; Rettberg, Petra (Public Library of Science (PLoS), 2017-10-25)
    The limits of life of aerobic microorganisms are well understood, but the responses of anaerobic microorganisms to individual and combined extreme stressors are less well known. Motivated by an interest in understanding the survivability of anaerobic ...
