Performance evaluation of bio-stimulants derived from commercially cultivated seaweeds for enhanced production of marine microalgal biomass, lutein, and bio-chemicals

Key Points

• Enhanced production of marine microalgal biomass was achieved using specific bio-stimulants, demonstrating significant effect.
• Samples treated with bio-stimulants showed an increase in lutein content by up to 30%, highlighting efficacy.
• Assessment using diverse commercial seaweed extracts revealed variability in bio-chemical yields across different strains.
• Findings suggest that bio-stimulants derived from seaweeds may enhance microalgae production, but further studies are needed.
