Abstract
The present invention relates to a novel process for purifying phycobiliproteins, in particular acid-pH-resistant phycobiliproteins, the resulting phycobiliproteins, and the uses thereof.
Claims6
A method for purifying acid-pH-resistant phycocyanins from a crude extract of acid-pH-resistant phycocyanins from cells of a phycocyanin-producing microorganism, said microorganism being of the genus Galdieria, said acid-pH-resistant phycocyanins being phycocyanins stable at a pH less than 5, and
- wherein the method comprises the steps of:
- a) adjusting the pH of the crude extract of acid-pH-resistant phycocyanins to a pH below 5 so as to precipitate organic matter other than acid-pH-resistant phycocyanins,
- b) recovering the supernatant comprising acid-pH-resistant phycocyanins obtained in step a) and
- c) isolating acid-pH-resistant phycocyanins from the supernatant of step b).
