ABSTRACT
A yeast strain Rhodotorula sp.NJ-298,which was isolated from antarctic sea-ice,could produce carotenoids pigment,and the total production was 1986?g?g~(-1).UV-visible spectrum and LC/MS analysis indicated astaxanthin was the major component of the carotenoids,and HPLC analysis showed its content accounted for 81.9 % of total carotenoids productoin.Maximum astaxanthin production 6506 ?g?L~(-1) was obtained when the yeast was grown at steady-state phase.Optimum temperature for the strain grow was at 8℃,and sodium acetate and peptone were the best carbon and nitrogen sources for the astaxanthin production.Moreover,the pigment had strong activity of scavenging free radicals,and the IC_(50) was 0.40 ?g?mL~(-1) by DPPH assay.
