Abstract

Green alga (Dunaliella salina) could produce high amount of β-carotene under extreme environmental conditions in order to defend its cells from extreme environmental stresses. β-carotene is widely used in various industries as antioxidant, provitamin A, food coloring, etc. In the present study, nitrogen deficiency and UV-C radiation are combined such as normal, UV, N-, and UV N- and used to culture Dunaliella salina to determine the best condition for cell growth and β-carotene production for 6 days. The cells were counted with a haemocytomenter, and β-carotene was extracted every three days. Result showed that normal culture Dunaliella salina had highest cell growth but lowest β-carotene production, while UV N- culture had lowest cell growth but highest β-carotene production. Environmental stress such as nitrogen deficiency and UV light can increase β-carotene production, but reduce cell growth as the side effect.
