Abstract
Algae (both micro and macro) have gained huge attention in the recent past for their high commercial value products. They are the source of various biomolecules of commercial applications ranging from nutraceuticals to fuels. Phycobiliproteins are one such high-value low volume compounds that are mainly obtained from micro and macroalgae. In order to tap the bioresource, a significant amount of work has been carried out for large scale production of algal biomass. However, work on downstream processing aspects of phycobiliproteins (PBPs) from algae is scarce, especially in the case of macroalgae. There are many difficulties in cell wall disruption of both micro and macro algae because of their cell wall structure and compositions. At the same time, there are several challenges in the purification of phycobiliproteins.
The current review article focuses on the recent developments in downstream processing of phycobiliproteins (mainly phycocyanins and phycoerythrins) from micro and macroalgae. The current status, recent advancements and potential technologies (that are under development) are summarised in this review article besides providing future directions for the present research area.
Keywords: Microalgae, macroalgae, phycobiliproteins, extraction, purification, downstream processing.
