title: Fluorescence from sensitizing phycobilin chromophores in the blue-green alga Anacystis nidulans.
abstract: Regeneration of the pigment system of Anacystis nidulans was studied following nitrate starvation. Three new, distinct fluorescence bands, at 596, 615 and 636 nm attributed to sensitizing phycobilin chromophores were detected. They each possess a separate excitation band at 425, 395 and 410 nm, respectively.
