ABSTRACT: ObjectiveTo investigate the most fitting condition for the fastgrowing of Haematococcus pluvialis fachb712. Methods The labor curve was made out to know the connection between the absorbency and the number of cells by the spectrophotometer and microscope. Then to discuss some of the main fitting condition from the cost of pH, the intension of illumination and the density of inoculation and the temperature. Results The most fitting conditions were as follows: pH 8.0, the intension of illumination was 1.0 klx, the time of continuous cultivation was 24 hours, the temperature was 24 ℃ and the density of inoculation was 1.95×105 mL1. Conclusion The condition of pH 8.0, the intension of illumination 1.0 klx, the time of continuous cultivation 24 hours, the temperature 24 ℃ and the density of inoculation 1.95×105mL-1 are fit for Haematococcus Pluvialis’s fastgrowing. ......
