Continuous microalgal cultures can overcome low productivity for high-value compounds. Harvesting beta-carotene from Dunaliella salina suggests potential for milking other secondary metabolites from microalgae.

Area of Science:

  • Biotechnology
  • Algal Biotechnology
  • Metabolic Engineering

Background:

  • Low productivity of algal cultures is a major barrier to commercializing high-value compounds.
  • Continuous cultivation with cell reuse offers a potential solution to enhance productivity.
  • A novel method for harvesting beta-carotene from Dunaliella salina in a two-phase bioreactor has been developed.

Purpose of the Study:

  • To investigate the feasibility of applying the "milking" process to mass produce secondary metabolites from microalgae.
  • To understand the mechanism of the milking process and its connection to product formation pathways.
  • To determine if various microalgal species can be utilized for milking different products.

Main Methods:

  • Utilizing a two-phase bioreactor system for microalgal cultivation.
