Phycoerythrin of the marine blue-green algaTrichodesmium thiebautii

摘要

Spectroscopic characteristics of the phycoerythrin obtained from the marine blue-green algaTrichodesmium thiebautiiwere investigated. The algal sample was collected at its natural habitat, the East China Sea. The phycoerythrin showed an absorption spectrum and a fluorescence excitation spectrum with three peaks in the visible wave-length region at 500, 547 and 565 nm. This property is very different from that of the cyanophycean phycoerythrin, which has a single peak at 565 nm, but it is similar to that of the rhodophycean phycoerythrin with three peaks at 500, 550 and 565 nm.
