Abstract

Plant raw materials are practically an inexhaustible natural resource, since they are constantly renewed in the process of plant photosynthesis, which determines the prospects for their use for industrial processing in various ways, including hydrolytic. The main biopolymer components of plant biomass in terms of their quantitative content are polysaccharides, the hydrolytic processing of which by acidic or enzymatic hydrolysis leads to the formation of monosaccharides and various products obtained from them. This review of scientific literature analyzes theoretical concepts and the current state of research on the development, improvement and prospects for the use of enzymatic hydrolysis of plant raw materials. The efficiency of this process and the composition of the resulting products largely depend on the features of the supramolecular structure of cellulose, the content of hemicelluloses and lignin in the raw material, the balance and activity of the cellulase complex of enzymes. It is shown that the main directions of development and improvement of the processes of enzymatic hydrolysis of plant raw materials at present are the production and use of more effective strains of microorganisms that produce highly active enzymes, the directed creation of complex enzymes (hydrolyzing not only cellulose, but also hemicellulose, as well as destroying lignin), the development of methods for pretreatment of raw materials to increase the reactivity of cellulose and remove lignin and improve the processes of fermentolysis.
植物原料酶解研究现状与展望
植物原料实际上是一种取之不尽、用之不竭的自然资源,因为它们在植物的光合作用过程中不断得到更新,这决定了它们在各种工业加工中使用的前景,包括水解。从数量上看,植物生物量的主要生物聚合物成分是多糖,通过酸水解或酶水解对其进行水解处理,形成单糖和由单糖得到的各种产品。本文综述了植物原料酶解的理论概念和研究现状,并对酶解技术的发展、改进和应用前景进行了展望。这一过程的效率和最终产物的组成在很大程度上取决于纤维素的超分子结构特征、原料中半纤维素和木质素的含量、酶的纤维素酶复合物的平衡和活性。结果表明,目前植物原料酶解工艺发展和改进的主要方向是生产和利用更有效的生产高活性酶的微生物菌株,定向创造复合酶(不仅水解纤维素,还水解半纤维素,以及破坏木质素),原料预处理方法的发展,以提高纤维素的反应性,去除木质素和改进发酵过程。
