摘要：An economic microalgae Haematococcus Pluvialis CH-1 was used as experimental material. An experiment of adding six grades of concentrations of Vitamin-B12 and Vitamin-H respectively was conducted. Cell density, biomass and astaxanthin content were measured. The results showed that the growth of H. Pluvialis was accelerated significantly by adding of Vitamin-B12 and Vitamin-H, respectively. The optimal adding concentration of Vitamin-B₁₂ and Vitamin-H respectively for H. Pluvialis and 500 &mug/L. Under the optimal concentration for H. Pluvialis, cells density, biomass and astaxanthin content were enhanced with Vitamin-B₁₂: 29.5, 30.0 and 28.3%; Vitamin-H: 17.1, 29.2 and 22.6% higher than the blank, respectively. On the mass culture of motile cells of H. Pluvialis, properly adding Vitamin-B12 and Vitamin-H, respectively was effective for increase cells density, biomass and astaxanthin content.
