Abstract

An economic microalgae Haemalococcus pluvialis CG-11. was used as experimental materia1, and was cultivated in the BBM medium. The influence of the physical factors(temperature, illumination and pH)on growth, chlorophylla content, carotenoid content, dry weight and astaxanthin content of the green vegetative cell was studied. These experiments were carried out separately as three single factor tests when four temperatures (16℃, 20℃, 24℃ and 28℃), four illuminations (30 μmol photons m^-2·s^-1, 60 μmol photons m^-2·s^-1, 90 μmol photons m^-2·s^-1, 120 μmol photons m^-2·s^-1) and four pH (6.0, 7.0, 8.0, 9.0) were adapted. The results showed that H. pluvialis CG-11. grew well in the range of 20～24℃. The optimum light intensity was about 90 μmoL photons m^-2·s^-1, and neutral or alkalescent environment was suitable to H. pluvialis CG-11. growth at pH 8.0.
