Separation and Partial Characterization of Membranes fromProchloronsp.1

摘要

Two differently colored membrane preparations were separated from the prochlorophyte,Prochloronsp., by mechanical disintegration of the cells followed by sucrose density gradient centrifugation. An orange-colored preparation, containing zeaxanthin as the major constituent pigment, seemed to comprise the cytoplasmic membrane. The other green-colored membrane preparation, containingβ-carotene and chlorophyllaandbas major pigment constituents, was identified as the thylakoid membrane. The two types of membranes were compared as to their absorption spectra and buoyant densities
