La Spirulina, un’alga antica

The blue-green algae or Cyanophyte to which Spirulina (Arthrospira platensis) belongs are the most primitive forms of algae, which appeared on Earth about four billion years ago. The only living beings capable of producing starch and vitamin B12, they were used as food by the Aztecs and the population of the Sahara, which, thanks to these algae, found in fresh or brackish water, were able to survive in adverse weather conditions. Currently, Spirulina is produced in aquaculture, a cultivation system with defined conditions of temperature and alkalinity.
