Influence of Critical Parameters on the Extraction of Concentrated C-PE from Thermotolerant Cyanobacteria.

This work aimed to identify the influence of pH, molarity, / fraction, extraction time, agitation, and either a sodium (NaHPO·7HO-NaHPO·HO) or potassium buffer (KHPO-KHPO) used in the extraction of C-phycoerythrin (C-PE) from a thermotolerant strain of sp. An experimental design (Minimum Run Resolution V Factorial Design) and a Central Composite Design (CCD) were used. According to the statistical results of the first design, the K-PO buffer, pH, molarity, and / fraction are vital factors that enhance the extractability of C-PE.

Impact of Biomass Drying Process on the Extraction Efficiency of C-Phycoerythrin.

Drying the biomass produced is one of the critical steps to avoid cell degradation; however, its high energy cost is a significant technological barrier to improving this type of bioprocess's technical and economic feasibility. This work explores the impact of the biomass drying method of a strain of sp. on the extraction efficiency of a phycoerythrin-rich protein extract.
