Abstract: The phycobilisomes (PBS) from the thermophilic cyanobacterium Myxosarcina concinna Printz and the PS Ⅱ particles from Spinacia oleracea Mill. were isolated. Their spectral characteristics were defined and the light energy transfer from PBS to PS Ⅱ was studied. As the ion intensity (KH2PO4) of the buffer system increased from 0.1 mol/L to 0.5 mol/L, the efficiency of the energy transfer also increased. The PS Ⅱ particles had a higher water splitting activity. When excited with light at 558 nm, there was a significant rise of the activity of O2 evolution which further indicated that the excitation energy harvested by PBS could transfer to the PS Ⅱ particle from spinach.
