Optimization of the Freezing-Thawing Method for Extracting Phycobiliproteins from Arthrospira sp.

ABSTRACT: The freezing-thawing method had been reported to be the best phycobiliprotein extraction technique. However, optimum parameters of this extraction method for Arthrospira sp. (one of the major phycobiliprotein sources) still remained unclear. Hence, this study aimed to optimize the freezing-thawing parameters of phycobiliprotein extraction in Arthrospira sp. (UPMC-A0087). The optimization of the freezing-thawing method was conducted using different solvents, biomass/solvent ratios, temperatures, time intervals and freezing-thawing cycles. The extracted phycobiliproteins were quantified using a spectrophotometric assay. Double distilled water (pH 7) with a 0.50% w/v biomass/solvent ratio was the most efficient solvent in extracting high concentrations and purity o
