Abstract. As the most recognizable natural secondary carotenoid astaxanthin producer, the green microalga Haematococcus pluvialis cultivation is performed via a two-stage process. The first is dedicated to biomass accumulation under growth-favoring conditions (green stage), and the second stage is for astaxanthin evolution under various stress conditions (red stage).
The microalga Haematococcus pluvialis has astaxanthin as the most economically valuable compound. However, there are challenges related to its cultivation and low biomass productivity.
