Raw mass spectra of soluble metabolites from "Multi-technique characterization of iron reduction by an Antarctic Shewanella: an analog system for putative Martian biosignature identification"

Raw mass spectra of supernatant collected from cultures of the Antarctic bacterial isolate Shewanella sp. BF02_Schw grown with and without 100 mM ferrihydrite. Supernatant was collect via pelleting and extracted using LC-MS grade methanol and sonication. Data were generated on a Thermo Scientific Vanquish Horizon Ultra High Performance Liquid Chromotography system and Q-Exactive HF-X Hybrid Quadrupole-Orbitrap Mass Spectrometer. The LC instrument was configured with a HSS T3 C18 column (Waters, 1.8 μm, 2.1 x 100 mm) using a VanGuard FIT precolumn and a VH-D10-A UV detector. Complete experimental details can be found in the accepted manuscript "Multi-technique characterization of iron reduction by an Antarctic Shewanella: an analog system for putative martian biosignature identification" in Applied and Environmental Microbiology.
