Phycocyanin Extraction from Spirulina Residue

Check if the same lab product or an alternative is used in the 5 most similar protocols
After extracting phycocyanin, Spirulina residue was collected from the East Algae Factory in Fuzhou, Fujian Province, China. The way of phycocyanin extraction provided by the factory was as follows: 50 kg Spirulina dry algae powder was added into 1200 kg water. During the dissolution, the temperature was controlled below 18 °C with additions of 20–30 kg calcium chloride, 3–5 kg citric acid, and 20 mL sodium hypochlorite. The mixture was first stirred for 3–5 h and maintained for 8 h, then 15–20 kg of disodium hydrogen phosphate was added and stirred for another 12 h to yield phycocyanin and Spirulina residues. Sulfathiazole (STZ, 98%), sodium hydroxide (NaOH, ≥ 98%), hydrochloric acid (HCl, 37%), sodium chloride (NaCl, ≥ 99.5%), and potassium bicarbonate (KHCO3, 99.5%) were acquired from Sinopharm Chemical Reagent Co., Ltd (Shanghai, China).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
