How the culture medium influences the growth of Arthrospira - Daruã Valente - Bog

The genus Arthrospira belongs to the Oscillatoriaceae family and comprises the group of cylindrical filamentous photosynthesizing cyanobacteria, known as blue-green microalgae. It has been used as food for humans for thousands of years. In 1974 it was declared THE BEST FOOD FOR THE FUTURE by the UN WORLD FOOD CONFERENCE, which aimed to eradicate hunger, food insecurity and malnutrition. For the WHO - UN World Health Organization - Arthrospira is an interesting food for many reasons, such as being rich in protein and iron and because it can be consumed without any risk. In commercial production, the choice of the composition of the culture medium is of great importance because 15 to 25% of the total production costs are due to the culture medium used for the development of the microorganism.
