Gloeobacter Violaceus — Further Investigation of an Unusual Photosynthetic Apparatus Pigment Changes in Response to Changes in Light Quality
Gloeobacter violaceus is an in numerous aspects unusual cyanobacterium, carrying the photosynthetic apparatus in the cytoplasmic membrane , . The typical long wavelength fluorescence emission of PS I at 77K is missing . The membrane is underlayed by phycobilisomes carrying phycourobilin in addition to phycoerythrobilin . An early publication suggests that there is no pronounced difference in the response of the organism to different light qualities during growth .
