Life cycle assessment of microalgal cultivation medium: biomass, glycerol, and beta-carotene production by <i>Dunaliella salina</i> and <i>Dunaliella tertiolecta</i>.

ABSTRACT:

Purpose

Dunaliella is a halophilic genus of microalgae with high potential in the global food market. The microalgal cultivation process contributes to not only economic impact but also environmental impact, especially regarding the artificial medium composition. In this context, a life cycle assessment was carried out to analyze the impacts associated with the components of the modified Johnson medium (MJM) and to predict the best scenarios to cultivate Dunaliella tertiolecta and Dunaliella salina for biomass, glycerol, and beta-carotene production.

Method

Two chains were analyzed separately: (1) Dunaliella salina (strain DF 15) cultivated in 8 scenarios combining different nitrogen (0.1 and 1.0 g L^-1 KNO₃) and magnesium (1.
