Nostoc is a very resistant macroscopic filamentous cyanobacteria, commonly found in terrestrial and aquatic habitats and able to fix atmospheric nitrogen. Nostoc colonies form lawns, nodules and even spheres, and can surprisingly retain viability as they are subjected to regular cycles of desiccation and hydration in their natural environment!
Why do we study it? ⬇️
Nostoc provides a wide range of remarkably protective physiological and pharmacological activities (antioxidant, anti-inflammatory, anti-carcinogenic, immune regulation…). It is hence an extremely valuable source of natural drugs for developing medicines and functional foods!
