Comparison of the accumulation of astaxanthin in Haematococcus pluvialis and other green microalgae under N-starvation and high light conditions

Abstract

Haematococcus pluvialis gave the highest astaxanthin accumulation rate (2.7 mg l−1 day−1) and total astaxanthin content ( 22.7 mg g−1 biomass). Astaxanthin accumulation in Neochloris wimmeri, Protosiphon botryoides, Scotiellopsis oocystiformis, Chorella zofingiensis and Scenedesmus vacuolatus was, respectively, 19.2, 14.3, 10.9, 6.8 and 2.7 mg astaxanthin g−1 biomass, respectively.
