Phylogenetic relationships of microalgal species studied for their use in food or food ingredients. Species designated with red are approved as GRAS (Generally Recognized as Safe) by the FDA. The phylogenetic tree is built using the phyloT tool (https://phylot.biobyte.de/, accessed on 16 January 2022) and is based on NCBI taxonomy. The classification of Shizochytrium sp. as microalga is questionable [40].
