Abstract:


Background: This review outlines to envisage the current impact of violacein-derivative materials in several technological areas through patents.

Methods: A comprehensive examination up to day patent databases on violacein demonstrated the relevance of this pigment, as well as the pertinent topics related to its technological development in order to obtain adaptable new pharmaceuticals, cosmetics and new quality fiber materials, together with others applications of violacein in different areas.

Results: At present time, there is no efficient and economical feasible technique for violacein preparation at industrial scale. Many attempts have been developed but none have achieved the big challenge of being effective and inexpensive process. However, some potential applications of violacein in fields like biomedicine make the pigment worth to continuous the investigations. Particularly, violacein patents covering from biosynthesis to different applications were reported recently.

Conclusion: As unique pigment, violacein has been used in distinct areas of specialties, such as in medical and industrial fields. Then, this review through patents provides an update on violacein innovations useful for researchers working in an expandable and interesting field of biotechnology with natural pigments.
