Abstract
Official abstract text for this publication.
The invention discloses microorganism cell culture conditions that result in increased cellular and media concentrations of a biological pigment. The invention has applications in use as a natural food colouring, as antioxidants in the food supplement industries, in the nutraceutical, pharmaceutical, and cosmeceutical industries, and a non-toxic ink. The method results in pigment that is relatively easy to separate from the microorganism culture.
First claim
Opening claim text (preview).
We claim: 1. A method for the synthesis of a phycocyanin, the method comprising the steps of (i) culturing a cyanobacteria in a growth medium and (ii) providing a source of light, wherein the light consists of electromagnetic radiation consisting of a wavelength of between 670 and 690 nm; and wherein the cyanobacteria in culture synthesizes increased levels of a phycocyanin. 2. The method of claim 1 , wherein the cyanobacteria is Arthrospira or Spirulina. 3. The method of claim 1 , wherein the electromagnetic radiation comprises an optimum emission wavelength of 680 nm. 4. The method of claim 1 , wherein the increased levels of the synthesized phycocyanin are at least 4.5-fold greater than levels of synthesized phycocyanin in the same cyanobacteria separately cultured in the presence of white light. 5. The method of claim 4 , wherein the synthesized phycocyanin leaches from the cyanobateria. 6. The method of claim 1 , wherein the phycocyanin is selected from the group consisting of a Spirulina phycocyanin and an Arthrospira phycocyanin.
