摘要

Abstract

Dunaliella salina

a halotolerant unicellular green alga

can accumulate a large amount of β-carotene under certain environmental conditions. The isomers of β-carotene extracted fromD. salina cultured in medium with different nitrate and phosphate concentrations were analysed by HPLC with Alox-T alumina column. At least six isomers were found in different proportions depending on the culture media's nitrate and/or phosphate concentrations. Nitrate and/or phosphate deficiency was conducive to the accumulation of total cis isomers but not of all trans isomer. It is suggested that 1 mmol/L KNO3 and 0.1 mmol/L KH2 PO4 are favourable for accumulation of total cis β-carotene.
