Exploring carbohydrate extraction from biomass using deep eutectic solvents: Factors and mechanisms.

Area of Science:

• Green Chemistry
• Biomass Conversion
• Carbohydrate Chemistry

Background:

• Deep eutectic solvents (DESs) are gaining attention as environmentally friendly solvents due to their low cost, low melting points, and biocompatibility.
• DESs exhibit desirable properties like stability and low toxicity, making them suitable for various applications, including biomass pretreatment.
• While DESs show potential in biomass pretreatment, their application in extracting carbohydrates from algal biomass is underexplored.

Purpose of the Study:

• To review the application of DESs in carbohydrate extraction from lignocellulosic and algal biomass.
• To investigate the relationship between DES properties and their efficacy in carbohydrate extraction.
• To elucidate the mechanisms of cellulose degradation induced by DESs.

Main Methods:

• Literature review of studies utilizing DESs for biomass carbohydrate extraction.
• Analysis of factors influencing DES performance in carbohydrate isolation.
• Examination of research on DES-mediated cellulose degradation pathways.

Main Results:

• DESs are effective in extracting carbohydrates from both lignocellulosic and algal biomass.
• DES properties, such as hydrogen bonding ability and viscosity, significantly impact extraction efficiency.
• Specific DES formulations can effectively degrade cellulose, facilitating carbohydrate release.

Conclusions:

• DESs represent a promising green technology for sustainable carbohydrate extraction from diverse biomass sources.
• Further research is needed to optimize DES formulations and understand their mechanisms for enhanced algal biomass carbohydrate extraction.
• DESs hold significant potential for future applications in biorefineries and the development of bio-based products.
