Progress in the study of fucoidan degradation

Area of Science:

• Marine biotechnology
• Biochemistry
• Polysaccharide chemistry

Background:

• Fucoidan, a sulfated polysaccharide, exhibits diverse biological activities and industrial applications.
• Low molecular weight fucoidan (LMWF) demonstrates superior bioavailability and efficacy compared to high molecular weight fucoidan.
• Enhanced absorption and physiological activities (antioxidant, anti-tumor, hypoglycemic) are linked to LMWF.

Purpose of the Study:

• To review and evaluate primary strategies for fucoidan degradation.
• To assess physical, chemical, and biological methods for producing LMWF.
• To highlight biodegradation as a sustainable and efficient degradation technique.

Main Methods:

• Overview of physical degradation methods (e.g., sonication, heat).
• Review of chemical degradation approaches (e.g., acid/alkaline hydrolysis).
• Exploration of biological degradation using enzymes or microorganisms.

Main Results:

• LMWF exhibits improved absorption and augmented bioactivities.
• Biodegradation offers environmental sustainability, high specificity, and product uniformity.
• Physical and chemical methods present limitations such as harsh conditions or by-product formation.

Conclusions:

• Fucoidan degradation is crucial for unlocking LMWF's potential.
• Biodegradation is a highly promising method for LMWF production.
• LMWF derived from sustainable biodegradation supports medical, food, and environmental goals.
