The keywords focus on viscosity reduction, nutrient recovery for feed, and oil extraction efficiency. These address the economic and physical barriers to converting raw microalgae into usable commercial products.

The keywords highlight the need for strains with easy intracellular oil extraction. Traditional microalgal cell walls are difficult to rupture, leading to high energy costs and solvent use during downstream processing.

Wild-type strains suffer from low simultaneous accumulation of proteins, lipids, and pigments. Overcoming this metabolic bottleneck allows for the industrial production of high-value biomass without compromising individual nutrient concentrations.
