Abstract / Description of output

The light harvesting phycobilisome complex is an important component of photosynthesis incyanobacteria and red algae. Phycobilisomes are composed of phycobiliproteins, includingthe blue phycobiliprotein phycocyanin, that are considered high value products with applications in several industries. Remarkably, several cyanobacteria and red algal species retain the capacity to harvest light and photosynthesise under highly selective environments such as hot springs and flourish in extremes of pH and elevated temperatures. These thermophilic organisms produce thermostable phycobiliproteins, which have superior qualities much needed for wider adoption of these natural pigment-proteins in the food, textile and other industries. Here we review the available literature on the thermostability ofphycobilisome components from thermophilic species and discuss how a better appreciation of phycobiliproteins from extreme environments will benefit our fundamental understanding of photosynthetic adaptation and could provide a sustainable resource for several industrial processes.
