Comments:	Reflectance spectrum of pure culture Rhodopseudomonas palustris (DSMZ (https://dsmz.de/) strain ID #8283). Measurements made with Ocean Optics USB2000+ UV/VIS spectrometer (grating #3) with Ocean Optics R400-7 reflectance probe.
                Visual color red-purple. Absorption maxima at 590 nm due to combination of spheroidene, spheroidenone and Bchl a; 800 nm and 850 nm due Bchl a. Strongest reflectance increases over 540-570 nm and 610-640 nm.
