Abstract  

Cell growth rate, chlorophyll a content, carotenoid content, dry weight, and astaxanthin content were measured to study the effects of nitrogen and phosphorus nutrients on the growth of green vegetative cells of Haemalococcus pluvialis CG-11 that was cultivated in BBM medium. The experiments were carried out separately as three single factor tests. It was found that both NaNO3 and NH4NO3 were suitable nitrogen sources for the cell growth. Suitable N concentration for the algae growth was 41.2 mg·L-1. Suitable P concentration for the algae growth was 5.33~53.3mg·L-1.

Key wordsHaematococcus pluvialis      green vegetative cell      nitrogen      phosphorus
