Depletion reveals role of bicarbonate in the photosynthetic electron transport chain of Limnospira maxima by Leslie Castillo, Stavroula Nicolaou, Colin Gates, Colin Gates

“…The hypercarbonate-requiring filamentous cyanobacterium Limnospira maxima has had multiple bicarbonate functions on both acceptor and donor side of PSII determined by depletion. 77K spectrofluorometric investigation of phycobilin and chlorophyll excitation suggests the mild in vivo depletion method for bicarbonate results in loss of chlorophyll connectivity to the reaction center in PSII and dissociation of the phycobilisome due to proportional increase of fluorescence emission from allophycocyanin. …”
