Extraction of Nannochloropsis Fatty Acids Using Different Green Technologies: The Current Path

Area of Science:

• Biotechnology
• Marine Biology
• Sustainable Chemistry

Background:

• Nannochloropsis microalgae are rich sources of polyunsaturated fatty acids (PUFA).
• Traditional lipid extraction uses hazardous organic solvents.
• Greener alternatives are needed to improve sustainability.

Purpose of the Study:

• To review recent (last 5 years) technologies for extracting fatty acids from Nannochloropsis.
• To assess methods for increasing extraction yields of valuable lipids.
• To identify optimal technologies for specific fatty acid recovery.

Main Methods:

• Review of extraction technologies including cell disruption and direct extraction.
• Analysis of independent and combined technology applications.
• Evaluation of extraction efficacy across different Nannochloropsis species.

Main Results:

• Various green technologies enhance fatty acid extraction from Nannochloropsis.
• Combined technologies often prove more effective than individual methods.
• Extraction efficiency and lipid profiles depend on the technology and Nannochloropsis species.

Conclusions:

• Tailored technology selection is crucial for efficient PUFA recovery, including eicosapentaenoic acid.
• A case-by-case assessment is necessary to optimize extraction for specific fatty acids.
• Advancements in green extraction technologies offer sustainable routes to valuable microalgal lipids.
