Pigment or Compound Name: Micrococcus luteus (in vivo, Schwieterman et al. 2015) Type: biological pigment Medium Type: whole cell Description: Reflectance spectrum of Micrococcus luteus x-axis label: wavelength x-axis units: nm y-axis label: reflectance y-axis units: fraction error label: error units: Source/Contact: Edward Schwieterman, University of Washington, eschwiet@uw.edu Reference: Schwieterman, E.W.; Cockell, C.S.; Meadows, V.S. 2015. Non-Photosynthetic Pigments as Biosignatures, Astrobiology, 15(5). Comments: Reflectance spectrum of pure culture of Micrococcus luteus (DSMZ (https://dsmz.de/) strain ID #20030). Measurements made with Ocean Optics USB2000+ UV/VIS spectrometer (grating #3) with Ocean Optics R400-7 reflectance probe. Visual color yellow. Absorption maxima at 450 nm and 485 nm due to beta- and/or keto-carotenes. Sharp increase in reflectance over 490-510 nm.
