Effect of Different Culture Media and Light Intensities on Growth of Haematococcus pluvialis

Abstract

The growth rate of H. pluvialis is controlled or regulated by the physical and chemical parameters. The aim of this study was to
investigate and compare the effect of various culture media and light intensities on the growth of H. pluvialis in batch culture. The
experiments were achieved by five different culture media and three different light intensities. The maximum cell concentration of
9.50 x 105cells ml-1, which corresponds to the growth rate of 0.195 d-1, was obtained in RM culture medium at the light intensity
of 40 µmol photons m-2 s-1. The cell concentration decreased by only 7% in Basal culture medium compared to RM culture medium
under the same light intensity.
