abstract：:The halotolerant alga Dunaliella bardawil accumulates very large amounts of [beta]-carotene when exposed to high light intensity. The accumulated [beta]-carotene is concentrated in small, oily globules within the chloroplast and has been suggested to protect the alga against photodamage by high irradiation (A. Ben-Amo...
