Última GROWTH AND TOTAL CAROTENOID CONTENT IN FOUR CHILEAN STRAINS OF HAEMATOCOCCUS PLUVIALIS FLOTOW, UNDER LABORATORY CONDITIONS Gayana Botánica González,Mariela A; Cifuentes,Ana Silvia; Gómez,Patricia I. Haematococcus pluvialis is a unicellular green microalga cultivated on a large scale as a natural source of astaxanthin, a ketocarotenoid of high commercial value due to its colorant and antioxidant properties. The aim of this study was to compare growth and total carotenoids among four strains of H. pluvialis isolated from different microhabitats in two geographical locations in Chile. Growth was carried out under autotrophic and mixotrophic conditions and under two photon flux densities (PFD) (20 and 85 umol nrV¹). Total carotenoid content was estimated on day 45. Most of the strains grew better under the autotrophic conditions; the highest exponential growth rates were exhibited at the high PFD in all the strains (ranging from 0.73 to 1.20 div day"¹)...
