Synthesis of polysaccharides by microalgae Chlorella sp

Area of Science:

• Biotechnology
• Marine Biology
• Food Science

Background:

• Microalgae are recognized as a primary natural source of polysaccharides.
• Polysaccharides derived from microalgae hold potential for various health applications.

Purpose of the Study:

• To assess the polysaccharide synthesis capabilities of Chlorella sp. microalgae.
• To identify optimal conditions for polysaccharide production in selected microalgal strains.

Main Methods:

• Cultivation of Chlorella sp. strains in Brody & Emerson max medium.
• Quantification of cell content, dry weight, neutral sugars, and uronic acids.

Main Results:

• IPPAS Chlorella pyrenoidosa exhibited increased cell content from 1.23 g/L to 1.71 g/L.
• Despite high dry weight (4.45 g/L), IPPAS Chlorella pyrenoidosa yielded lower neutral sugars (0.75 g/L) and uronic acids (0.14 mg/L).
• IPPAS Chlorella vulgaris (1.18 g/L dry weight) produced 0.80 g/L neutral sugars and 0.17 mg/L uronic acids.

Conclusions:

• Chlorella sp. microalgae effectively synthesize polysaccharides.
• Microalgal polysaccharides show promise as functional ingredients in food additives due to their health benefits.
