摘要
黏土矿物作为一类天然纳米结构硅酸盐非金属矿物材料,以其比表面积大、生物相容性好、价廉易得等优势而成为酶固定化、构建纳米结构酶复合体系的理想载体。本文综述了近年来以黏土矿物为载体构建的纳米结构酶复合体系及其应用进展,包括以黏土矿物为载体制成的纳米结构酶,以改性黏土材料为载体制成的纳米结构复合酶,以及以改性黏土矿物为囊壁材包封酶制成的黏土矿物基纳米复合酶仿生微囊。纳米结构酶复合体系的构建,不仅提高了酶的催化效率,还增强了酶在复杂环境中的耐用性和重复使用性,在降低酶工业化成本的同时,也为黏土矿物的高值化利用开拓了新方向。
Clay minerals, a series of natural nanostructured silicate non-metallic mineral materials, are ideal supporters of the construction of nanostructured enzyme complex system for the enzyme immobilization due to their advantages of the large specific surface area, good biocompatibility, low cost and easy availability. In this article, we have comprehensively reviewed latest advances on the utilization of clay minerals as solid supporters for the construction of nanostructured enzyme complex systems, including the clay mineral-based nanostructured enzyme, the modified clay mineral-supported nanostructured compound enzyme, and the clay mineral-based compound enzyme bioinspired microcapsule made by using the modified clay minerals as capsule wall for encapsulating enzyme. The construction of nanostructured enzyme complex systems not only has improved the catalytic efficiency of the enzyme, enhanced the durability and reusability of the enzyme in harsh environments, but also has reduced the cost of the enzyme industrialization and provided a new direction for the high-value utilization of clay minerals.
