Enhanced phycocyanin and protein content of Arthrospira by applying neutral density and red light shading filters: a small-scale pilot experiment Hasselt University KU Leuven
BACKGROUND: The cyanobacterium Arthrospira contains proteins and the blue pigment phycocyanin that can be used as a natural colourant in the food industry. The aim of this study was to investigate a strategy for increasing the yield of phycocyanin and protein from Arthrospira cultures by shading the cultures with neutral density and red light filters.
