Bioprocess Strategy of Haematococcus lacustris for Biomass and Astaxanthin Production Keys to Commercialization: Perspective and Future Direction

Haematococcus lacustris (formerly called pluvialis) is regarded as the most promising microalgae for production of natural astaxanthin, which secondary metabolism used a dietary supplement, also cosmetic applications, due to its high anti-oxidant activity. Astaxanthin has wide range biological activities and economic potential, currently dominates market in synthetic form. Furthermore, because difficulty bioprocess cost cultivation, astaxanthin extracted from this microalga still expensive low biomass pigment productivities. Large-scale biotechnological necessitates processing large number cultures well use both indoor outdoor systems, such open pond raceway systems photo-bioreactors (PBR). The are suitable mass growth conditions can be controlled, risk contamination reduced certain extent under specific culture parameters. This review discusses current technologies being developed improve cultivation operation efficiency profitability, effect parameter factors associated with H. on bioproduction, even strategies increasing bioproduction potential astaxanthin.
