Naturally produced blue pigment expressed in bacterial strain to produce significantly higher yields of the blue pigment and do so without using synthetic compounds. Issued patent.
About
Researchers at Utah State took a blue tint originally synthesized from a bacterial strain that does not produce significant quantities of indigoidine and mimicked the organism’s biosynthetic machinery inside a heterologous host cell: E. coli. These mostly harmless bacteria can produce significantly higher yields of the blue pigment and do so without using synthetic compounds that could pose a threat to human health and the environment. The blue color of the indigoidine compound is bright and sustainable. As a natural dye, it has promising health benefits as an antioxidant and antimicrobial actor. Because of a new purification process patented with the compound, indigoidine natural blue dye is safe to use in food and drinks. Indigoidine natural blue dye is a promising alternative to the synthetic dyes used to colored jeans, leather, food, beverages, cosmetics and paper.
