“…Firstly, at higher PUF-immobilized ratios, there may be a decrease in the accessibility of the immobilized lipase to substrate molecules due to overcrowding or steric hindrance, leading to reduced catalytic activity despite higher protein loading [36]. Secondly, changes in the immobilization ratio may influence the orientation and distribution of immobilized lipase molecules on the PUF matrix, affecting the efficiency of enzyme-substrate interactions and subsequent catalytic activity [37]. Additionally, higher immobilization ratios may result in increased diffusion limitations for substrates and products within the porous structure of the PUF matrix, leading to decreased enzyme activity due to mass transfer limitations [13].…”

The low cost and excellent catalytic properties of lipase for industrial processes are highly desirable. A promising new approach involves the support modification of lipase and spacer arm, which enables the enhancement of lipase properties. This study investigates the immobilization of crude lipase from Mucor miehei onto a Polyurethane Foam (PUF) surface using various coating techniques. The PUF matrix was obtained through isocyanate and polyol reactions. Subsequently, the PUF was coated by adsorbing lipase and adding edible support material. The immobilized lipase was then utilized in the hydrolysis of coconut oil to produce fatty acids. Furthermore, the immobilized enzyme was employed in the esterification of fatty acids to produce bio-flavors. The results demonstrate that the attachment reaction using support material, namely lecithin, gelatin, MgCl2, and Polyethylene glycol 6000 (PEG), all of which are simple and edible, was able to enhance the stability and reusability of lipase. This immobilization technique increased triglyceride hydrolysis into FFA by 422%. The successful edible support modification of immobilized lipase from M. miehei on PUF, coupled with significantly enhanced enzyme stability and catalytic activity, offers a promising, environmentally friendly solution for diverse applications in the food industry.

Immobilization of lipases by physical adsorption improves their stability, recovery, and reusability in biotechnological processes. The present review provides an advanced bibliometric analysis and a comprehensive overview of research progress in this field. By searching Web of Science, 39,575 publications were analyzed, and 325 relevant articles were selected. Key journals, countries, institutions, and authors were identified. The most cited articles focus on biofuel production and industrial applications. The analysis revealed four research themes with a focus on the production of biofuel. The physical adsorption method is effective when the appropriate support is used. Despite a decrease in patent applications, industrial interest remains high. Future studies should focus on optimizing support materials and exploring new applications of this technique. The present review provides a detailed understanding of the immobilization of lipases by physical adsorption.
