Abstract

The phycoerythrin characterization from Nostoc sp. strain A5 was done, followed by investigation of its biological activity for biotechnological applications. For phycoerythrin extraction, the use of acetate buffer (pH 5.1) resulted in 65.04 µgmL-1, and C-phycoerythrin was identified. Results of its antioxidant activity suggested action as a potent free radical scavenger. In addition, Nostoc's C-phycoerythrin showed noteworthy ability for antibacterial and antifungal agents with significant stability up to 10 days. Glucose (4 mgmL-1) was a good preservative for C-phycoerythrin at 25 and 4 ºC. A stable C-phycoerythrin from Nostoc sp. was obtained for the first time from limestone drought conditions, showing the need of studying microorganisms from extreme environments.
