A variety of commercially valuable pigments, including carotenoids, phycobiliproteins, and chlorophylls, are produced by microalgae, which are diverse eukaryotic microorganisms capable of photosynthesis. The food, cosmetic, and pharmaceutical industries all use these pigments. Microalgae’s strong cell walls make extraction essential, necessitating techniques like mechanical disruption, freeze-thaw cycles, and enzymatic hydrolysis to maximize pigment release. Pigments are separated and quantified using sophisticated HPLC and mass spectrometry techniques, and solvent-based extractions and supercritical CO₂ extraction methods are used. Some species, such as Haematococcus pluvialis for astaxanthin and Dunaliella spp. for β-carotene, are recognized for their distinct pigment profiles. A thorough approach to microalgal pigment recovery is presented in this work, enabling scalable biotechnology applications and sustainable production.

摘要

A variety of commercially valuable pigments, including carotenoids, phycobiliproteins, and chlorophylls, are produced by microalgae, which are diverse eukaryotic microorganisms capable of photosynthesis. The food, cosmetic, and pharmaceutical industries all use these pigments. Microalgae’s strong cell walls make extraction essential, necessitating techniques like mechanical disruption, freeze-thaw cycles, and enzymatic hydrolysis to maximize pigment release. Pigments are separated and quantified using sophisticated HPLC and mass spectrometry techniques, and solvent-based extractions and supercritical CO₂ extraction methods are used. Some species, such as Haematococcus pluvialis for astaxanthin and Dunaliella spp. for β-carotene, are recognized for their distinct pigment profiles. A thorough approach to microalgal pigment recovery is presented in this work, enabling scalable biotechnology applications and sustainable production.
