Effect of Vitamins on DHA Production of Schizochytrium

Abstract:

In the manuscript,the effect of VB12,biotin,VB1,VB5,VB6on the growth of Schizochytriumsp.JN-168 and DHA production were studied with single factor experiment. The results showed that the additon of vitamins could efficient increase the DHA yield and the a optimum concentration were 0.1,0.005,0.005,0.3,0.05 mg/L,respectively. Amongt them,it was found that the highest DHA yield was achieved by VB12addition. Then follow by VB6,VB3,biotin and VB1. Futhermore,the simultaneously addition of these five kinds of vitamins with the optimum concentration could greatly improve the DHA yield. The final DHA yield was increased by 53.8%compared to the value of the control.
