Area of Science:

• Biocatalysis and Enzyme Engineering
• Materials Science for Biotechnology
• Chemical Engineering and Bioreactor Design

Background:

• Lipases are crucial biocatalysts for hydrolysis and synthesis, exhibiting high selectivity.
• Enzyme immobilization is key for enzyme recovery, stabilization, and reuse in industrial processes.
• Polyvinyl alcohol (PVA) is a promising support material for enzyme immobilization.

Purpose of the Study:

• To review the immobilization of lipases using polyvinyl alcohol (PVA) as a support material.
• To explore PVA's combinations with alginate, chitosan, and hydroxypropylmethylcellulose (HPMC).
• To assess the incorporation of magnetic properties, fibers, and microspheres in PVA-based lipase immobilization.

Main Methods:

• Literature review of articles published between 1999 and 2023.
• Selection of articles from the Scopus database.
• Analysis of 42 selected articles focusing on PVA-based lipase immobilization techniques.

Main Results:

• PVA, when combined with other materials like alginate and chitosan, offers diverse functionalization for lipase immobilization.
• The formation of fibers and microspheres, along with magnetic properties, enhances biocatalyst performance.
• PVA-supported immobilized lipases demonstrate significant versatility for various bioreactor configurations.

Conclusions:

• Polyvinyl alcohol (PVA) is a highly versatile material for developing advanced immobilized lipase systems.
• Combinations of PVA with other polymers and functional additives expand immobilization possibilities.
• Further research is needed to fully exploit PVA's potential in scalable lipase applications across different bioreactors.
