不同ｐＨ对多变鱼腥藻（Ａｎａｂａｅｎａｖａｒｉａｂｉｌｉｓ）藻胆体荧光发射光谱，光能传递和解离的影响．在ｐＨ７磷酸缓冲溶液中，藻胆体处于稳定状态，不发生解离．在ｐＨ６，８，９，１０磷酸缓冲溶液中，藻胆体仍处于较稳定状态，没有解离．在ｐＨ５，５．５和１０．５磷酸缓冲溶液中，藻胆体发生弱解离．在ｐＨ４．５缓冲溶液中，藻胆体发生明显解离．在ｐＨ４和１１缓冲溶液中，藻胆体发生严重解离；藻红蓝蛋白，Ｃ－藻蓝蛋白和别藻蓝蛋白所捕获的光能已不能传递给末端发射体
Effect of Different pH on Fluorescence Emission Spectra, Light Energy Transfer and Dissociation of Phycobilisomes from Anabaenavariabilis. In pH7 phosphate buffer solution, phycobilisomes are stable and do not dissociate. In pH6,8,9,10 phosphate buffer solution, phycobilisomes are still in a more stable state, there is no dissociation. Phycobilisomes dissociated weakly in pH5, 5.5 and 10.5 phosphate buffered solutions. In pH4.5 buffer solution, phycobilisomes obviously dissociated. The phycobilisomes were severely dissociated in pH 4 and 11 buffer solutions; the light energy captured by phycocyanin, C-phycocyanin, and allophycocyanin was no longer delivered to the end emitters
