Azolla, often referred to as water fern, is emerging as a promising solution to the global food crisis. This floating fern boasts an impressive growth rate, capable of doubling its biomass in just two days, and can thrive in nutrient-poor water without the need for nitrogen fertilizers. It contains Nostoc azollae, a cyanobacterium that fixes atmospheric nitrogen, positioning Azolla as a potential food source and biofertilizer, thereby supporting sustainable agriculture. Recent studies have confirmed the safety of Azolla for consumption, addressing earlier concerns about cyanotoxins, which are harmful compounds sometimes linked to cyanobacteria. Research conducted by Penn State and other institutions has shown no significant levels of these toxins in Azolla, ensuring its safety for both human and animal consumption. This finding enhances Azolla's potential as an alternative protein source, particularly in areas facing food insecurity. In addition to its nutritional advantages, Azoll...
