Abstract The freshwater green algaHaematococcus pluvialis (Strain Vischer 1923/2) grows best at high nitrate concentrations (about 0.5 to 1.0 g 1−1 KNO3), intermediate phosphate concentration (about 0.1 g 1−1 K2HPO4) and over a wide range of Fe concentrations. Low nitrate or high phosphate induce the formation of reddish palmella cells and aplanospores. Mixotrophic growth with acetate improves growth rate and final cell yield, and also stimulates the formation of the astaxanthin-containing palmella cells and aplanospores.H. pluvialis cannot grow above about 28 °C, or above a salinity of approximately 1% w/v NaCl. An increase in temperature or the addition of NaCl also stimulates the formation of palmella cells and aplanospores.
