Problems solved by technology

However, in the process of enzymatic hydrolysis, due to the irreversible adsorption of some cellulase and hemicellulase on the surface of the substrate, especially the lignin, the enzyme activity will be lost. In addition, the crystal structure of the cellulose itself and the hemifiber The complexity of the protein structure is also an important factor leading to low hydrolysis efficiency.

Description

technical field [0001] The invention belongs to the technical field of biomass energy, and in particular relates to a method for preparing sugar liquid fermented by plant vines. Background technique [0002] With the growth of population, food, energy and environment are the most important challenges facing human beings. The production of renewable clean energy from cellulosic raw materials has attracted increasing attention, and the production of fuel ethanol from crop wastes is considered to be the most promising industry. Economic crops such as watermelons, pumpkins, sweet potatoes, and lentils are planted in a wide area in my country, and almost the same amount of vines are produced every year when the fruits are harvested. The protein content in the vine is low but the carbohydrate content is high, and the carbohydrate content of individual varieties is as high as 82% of the dry matter, so it is a high-quality raw material for the production of biomass energy.
