Different characteristics of C-phycocyanin (C-PC) in two strains of the extremophilic Galdieria phlegrea

To date, the main source for phycocyanin production is the thermophilic cyanobacterium Spirulina platensis, although latest researches are exploring the possibility to exploit the thermoacidophilic Cyanidiophyceae (Rhodophyta) to this purpose. Galdieria phlegrea is a polyextremophilic red alga belonging to Cyanidiophyceae, colonizing, along with G. sulphuraria, acidic and thermal environments and distinguishable from this latter on the base of...
