| Abstract: |
| As β-carotene, the precursor of vitamin A, can improve eyesight at night, provide nutrition for the skin, has potential anti-cancer and ant-ageing functions, and can reduce the incidence of cardiovascular diseases, it (natural β-carotene especially) is now in great demand.
The culture of Dunaliella salina for producing β-carotene as a hot research area in micro-algal biology, was detailedly studied in the past decade and will be greatly developed in the 1990’s and the next century.
The studies covered 1) the biology and culture of D. salina, to 2) β-carotene isomers, and 3) the physiology of β-carotene accumulation. This paper points out some existing problems and future potential research fields to include (1) kinetics of β-carotene formation induced by changing environmental factors, (2) establishment of optimized models for cell growth, for producing β-carotene and its cis isomers, (3) effects of phytohormones and plant growth regulators (especially ABA and the other growth inhibitors) on β-carotene accumulation, (4) β-carotene biosynthetic pathways and their key enzymes, and (5) the physiological functions of β-carotene accumulation. ` |
