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 coloring, 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 system for producing increased levels of phycocyanin, the system comprising a vessel and a lamp, wherein the lamp provides a source of light, wherein the light consists of electromagnetic radiation consisting of a wavelength of between 670 and 690 nm, and wherein the vessel further comprises a cyanobacteria in a growth medium, and wherein the cyanobacteria synthesizes increased levels of phycocyanin compared to that of cyanobacteria separately cultured in the presence of white light. 2. The system of claim 1 , wherein the cyanobacteria is Arthrospira or Spirulina. 3. The system of claim 1 , wherein the electromagnetic radiation comprises a maximum wavelength emission of 680 nm. 4. The system of claim 1 , wherein the increased levels of 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 system of claim 1 , wherein the vessel is selected from the group consisting of a tank, a bioreactor, a pond, and an open raceway.
