UV–visible absorption spectra of the carotenoids extracted from Halorubrum sp. TBZ126. bacterioruberin (a), lycopene (b) and β-carotene (c) detected by G1315B Diode Array Detector. The maximum absorption wavelengths for the carotenoids of interest are 466 nm, 495 nm and 528 nm for bacterioruberin, 448 nm, 474 nm and 505 nm for Lycopene and 425 nm, 455 nm and 482 nm for β-carotene.
