In view of the multiple uses of phycoerythrin, in
the present work a scaleable methodology for
purification of large amounts of pure -phycoerythrin
from the red algae P. cruentum is proposed.
The yield of the process at various stages is
analysed. The high purity of B-PE obtained was
confirmed by SDS-PAGE electrophoresis and the
spectroscopic characterization of B-PE. Finally,
the economic aspects of the process are discussed.
