The main carotenoids of Cyanidium caldarium are β-carotene and zeaxanthin; these observations support the view that this alga represents a transitional form between the cryptomonads and the green algae. The distribution of polyenes and carotenoids in a number of ultra-violet induced mutants of Chlorella pyrenoidosa is described., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-23-1-93
