About this Research Topic
Enzymatic and whole cell catalysis are highly efficient and sustainable methodologies in modern industry that have been extensively applied in various chemical and biological processes. However, the fragile nature of natural enzymes and cells makes them vulnerable to harsh practical environments, leading to poor operational stability, laborious recycling, shortened life span and extremely high cost. To solve such problems, biocatalyst immobilization has been considered to be an efficient route to improve catalytic performances of natural enzyme and cell. It refers to biocatalysts physically or chemically localized in/on a certain defined region of selected supports via adsorption, covalent binding, cross-linking or encapsulation. In particular, the supporting materials and immobilization techniques are of great significance in improving the catalytic performance of natural biocatalysts; thus, the exploitation of efficient novel immobilization materials and techniques are very important and have attracted substantial attentions in recent years.
In the past few decades, great progress has been made in the field of enzyme and whole cell immobilization. However, those biocatalysts still suffer from leaching, denaturation or inactivation, and restricted mass transfer, leading inevitably to a loss of their activities and service life. Accordingly, new theories, techniques and methodologies should be constantly developed to solve such problems. Especially, the following issues deserve attention and should be tackled:
(1) Design or discovery of novel enzyme/whole cell supporting materials with high loading capacity, favorable chemical and mechanical stability, wide applicability, high biocompatibility, as well as low cost;
(2) Development of advanced immobilization techniques, which allow the immobilization process to be facilely achieved with ideal repeatability, and retain the activity of biocatalyst to a maximum extent;
(3) Biocatalysis and its process regulation in non-aqueous systems, such as deep eutectic solvent and ionic liquid, to realize efficient transformation of selected substrates;
(4) Deeply revealing the interaction mechanisms between enzyme/whole cell and the supporting platforms from both chemical and biological perspectives, to rationally guide the design of supporting materials and immobilization processes;
(5) The application of immobilized enzyme or whole cell in the production of high-value added chemicals, especially energy related substances, functional food ingredients, pharmaceutical intermediates, etc.
The following areas can be covered in the scope of this Research Topic:
• Novel enzyme or whole cell immobilization materials;
