What is it about?
Carotenoids are pigments, which play a major role in the protection of cyanobacteria and other living organisms against photooxidative damage. The filamentous heterocystous nitrogen-fixing cyanobacterium Calothrix sp. 336/3 possesses a wide variety of different carotenoids allowing this benthic strain to cope with harsh environmental conditions. This work shows that under severe nitrogen deficiency Calothrix accumulates glycosylated and hydroxylated carotenoids. This property can be further applied for the industrial production of carotenoids with high antioxidant activities.

Why is it important?
Carotenoids are important compounds, which are widely used in food, feed and biomedical industries. Cyanobacteria provide a great opportunity for production of unique carotenoids with enhanced antioxidative properties.
