Haematococcus pluvialis is a green freshwater microalgae species, well known for its ability for astaxanthin accumulation. Astaxanthin is a high-value red carotenoid pigment commonly used in the food, feed and cosmetics industries due to its well-known antioxidant, anti-inflammatory and antitumour properties. In the present study, the impact of pH, various concentrations of, NaCl, and different media were analysed on the vegetative cells of Haematococcus pluvialis. The experiment was conducted for 18 days and data were analyzed at the interval of 2 days, maximum concentration of total carotenoid were 4.133µgml-1 at pH 7.0, 20mM and 40mM NaCl 7.407 µgml-1respectively. The organism had highest content of carotenoid of 4.056 µgml-1 in Bold Basal Medium as against other medium on 14th day.
