Abstract:
This paper reported the suitable medium of L S-1 stain in detail,which could yield natural blue pigment.Single-factor exper imental design shows that the best carbon source was 2% glucose and nitrogen was 0 1% KNO 3.Orthogonal experimental design shows that the most suitable fermen tation medium was consisted of 4% glucose,0 1% KNO 3,0 075% salt and 10?g/m L FeSO 4.The best cultivation temperature was 30℃ and pH7 4.The dissolved oxyg en on the process of fermentation,as well as the variety of pH and the utilized condition of carbon and nitrogen were measured and analyzed.The separation of th is blue pigment by HPLC shows that this material contains actinorhordin and at l east other four ingredients.
