Biocatalytic processes in ionic liquids: a green platform for a sustainable future

Area of Science:

• Green chemistry and biocatalysis.
• Sustainable chemical synthesis and engineering.

Background:

• Enzymes offer sustainable, biodegradable catalysis with high selectivity under mild conditions.
• Traditional chemical processes often generate significant waste and require harsh conditions.
• Ionic liquids (ILs) are emerging as key tools for sustainable enzymatic and chemoenzymatic processes.

Purpose of the Study:

• To review the synergistic effects of combining ionic liquids (ILs) with biocatalysts.
• To illustrate how ILs enable the design of green platforms for sustainable chemical production.
• To highlight the role of ILs in achieving efficient biocatalytic transformations and product separation.

Main Methods:

• Review of existing literature and case studies on IL-biocatalyst systems.
• Analysis of IL properties that enhance enzyme activity, stability, and selectivity.
• Examination of IL-based reactor designs, such as IL/scCO2 biphasic systems and sponge-like ILs, for efficient separation.

Main Results:

• The combination of ILs and biocatalysts significantly enhances catalytic efficiency and selectivity.
• ILs facilitate straightforward product separation, reducing downstream processing.
• Synergistic effects between ILs and enzymes lead to highly efficient and sustainable processes.
• IL-biocatalyst systems are crucial for developing circular economy approaches in the chemical industry.

Conclusions:

• The strategic combination of biocatalysts and IL technologies is a powerful strategy for developing green chemical platforms.
• ILs are indispensable for advancing sustainable enzymatic and chemoenzymatic processes.
• These integrated approaches pave the way for a more sustainable future in chemical manufacturing.
