Phycoerythrin (PE) is a photosensitive red pigment from phycobiliprotein family predominantly present in the red algae. The concentration of PE depends on photon flux density (PFD) and the quality of light absorbed by the algae tissue. This necessitates robust techniques to extract PE from the embedded cell-wall matrix of the algal frond. Similarly, PE is sensitive to various factors which influence its stability and purity of PE. The PE is extracted from Red algae through different extraction techniques. This review explores an integrative approach of fractionating PE for the scaling-up process and commercialization. The mechanism for stabilizing PE pigment in food was critically evaluated for further retaining this pigment within the food system. The challenges and possibilities of employing efficient extraction for industrial adoption are meticulously estimated. The techniques involved in the sustainable way of extracting PE pigments improved at a laboratory scale in the past decade. Although, the complexity of industrial-scale biorefining was found to be a bottleneck. The extraction of PE using benign chemicals would be safe for food applications to promote health benefits. The precise selection of encapsulation technique with enhanced sensitivity and selectivity of the membrane would bring better stability of PE in the food matrix.

Abstract
Three strains of chlorophyte microalgae indigenous in Norway were studied regarding their potential for nutrient removal and resource recovery from wastewater. The nutrient uptake, growth, and cell composition (total proteins and carbohydrates) were monitored under a controlled batch environment for 14 days. Additionally, the fatty acids were analyzed at the end of the study. The fastest nutrient removal was achieved by Lobochlamys segnis F12 that used up NH4+ (28 mg L-1) and PO43- (15 mg L-1) after 4 days. Similar PO43- uptake was achieved by Tetradesmus wisconsinensis H1 while its NH4+ uptake took 2 days longer. Both strains showed a higher specific growth rate (1.1 day-1) than Klebsormidium flaccidum NIVA-CHL80 (0.55 day-1). The highest biomass (1.276 ± 21 mg L-1) and carbohydrates content (40%) were achieved by T. wisconsinensis. K. flaccidum was characterized by superior protein content (53 ± 4%). In terms of total fatty acids production both K. flaccidum and L. segnis were favored (184 ± 6 and 193 ± 12 mg g-1 dry cells), especially with their high polyunsaturated fatty acid content (82 and 67%, respectively). The fatty acids of K. flaccidum consisted mainly C18:2 n-6 (73% of the total). L. segnis had a preferable n3 to n6 ratio (1.3) in their fatty acid profile. The proteins and carbohydrates content changed in all strains depending on the growth stage. Therefore, resource recovery scenarios could be further optimized for a specific cell component production combined with an appropriate strategy for nutrient removal from wastewater.
