Enzymes are the highly versatile bio-catalysts having the potential for being employed in biotechnological and industrial sectors to catalyze biosynthetic reactions over a commercial point of view. Immobilization of enzymes has improved catalytic properties, retention activities, thermal and storage stabilities as well as reusabilities of enzymes in synthetic environments that have enthralled significant attention over the past few years. Dreadful efforts have been emphasized on the renewable and synthetic supports/composite materials to reserve their inherent characteristics such as biocompatibility, non-toxicity, accessibility of numerous reactive sites for profitable immobilization of biological molecules that often serve diverse applications in the pharmaceutical, environmental, and energy sectors. Supports should be endowed with unique physicochemical properties including high specific surface area, hydrophobicity, hydrophilicity, enantioselectivities, multivalent functionalization which professed them as competent carriers for enzyme immobilization. Organic, inorganic, and nano-based platforms are more potent, stable, highly recovered even after used for continuous catalytic processes, broadly renders the enzymes to get efficiently immobilized to develop an inherent bio-catalytic system that displays higher activities as compared to free-counter parts. This review highlights the recent advances or developments on renewable and synthetic matrices that are utilized for the immobilization of enzymes to deliver emerging applications around the globe.
酶是高度多功能的生物催化剂,具有在生物技术和工业领域中应用的潜力,可在商业角度催化生物合成反应。酶的固定化提高了酶在合成环境中的催化性能、保留活性、热稳定性和储存稳定性以及可重复使用性,这在过去几年引起了广泛关注。人们一直在努力研究可再生和合成载体/复合材料,以保留其固有特性,如生物相容性、无毒、大量反应性位点的可及性,这些特性通常可用于制药、环境和能源等领域的多种应用。载体应具有独特的物理化学性质,包括高比表面积、疏水性、亲水性、对映选择性、多价官能化,这些性质使它们成为酶固定化的合适载体。有机、无机和基于纳米的平台更有效、更稳定、更易回收,即使在用于连续催化过程后也是如此,这使得酶能够有效地固定化,从而形成内在的生物催化体系,与游离酶相比具有更高的活性。本综述重点介绍了可再生和合成基质的最新进展或发展,这些基质用于酶的固定化,以在全球范围内提供新兴应用。
