Gloeobacter violaceus is an in numerous aspects unusual cyanobacterium, carrying the photosynthetic apparatus in the cytoplasmic membrane [1], [2]. The typical long wavelength fluorescence emission of PS I at 77K is missing [3]. The membrane is underlayed by phycobilisomes carrying phycourobilin in addition to phycoerythrobilin [4]. An early publication suggests that there is no pronounced difference in the response of the organism to different light qualities during growth [1].
