Embodiment 1

[0028] The hydrolysis and saccharification process of Asteroides spinosa described in the present embodiment specifically comprises the following steps:

[0029] (1) Choose 500g Hollow Lotus Seed Grass as raw material, put the Hollow Lotus Seed Grassland material into the drum sieve with several bar magnets distributed in parallel on the inner wall of the drum, open the drum sieve to remove impurities and metal, rotate for 30min, and collect the hollow lotus seeds Grass raw material, and then put the collected hollow lotus grass raw material into the press to realize solid-liquid separation, and obtain solid and liquid substances;

[0030] (2) After drying and pulverizing the solid obtained in step (1), drop into an electrolytic cell filled with sulfuric acid solution (concentration is 2%) and stir and dissolve to form a solution. Two carbon electrodes are arranged in the electrolytic cell, and the carbon The electrode power supply is used to treat the solution in the electrol...

Embodiment 2

[0034] The hydrolysis and saccharification process of Asteroides spinosa described in the present embodiment specifically comprises the following steps:

[0035] (1) Choose 500g Hollow Lotus Seed Grass as raw material, put the Hollow Lotus Seed Grassland material into the drum sieve with several bar magnets distributed in parallel on the inner wall of the drum, open the drum sieve to remove impurities and metal, rotate for 30min, and collect the hollow lotus seeds Grass raw material, and then put the collected hollow lotus grass raw material into the press to realize solid-liquid separation, and obtain solid and liquid substances;

[0036] (2) After drying and pulverizing the solid obtained in step (1), drop into an electrolytic tank filled with sulfuric acid solution (concentration is 1.5%) and stir and dissolve to form a solution. Two carbon electrodes are arranged in the electrolytic tank, and the carbon The electrode power supply is used to treat the solution in the electr...

Abstract

The invention relates to a process of hydrolysis and saccharification of A. japonicus, which adopts magnetic force to absorb metal pollutants (iron, cobalt, nickel) in the raw material of A. japonicus, reduces subsequent mechanical wear and the content of metal ions in the final treatment solution, and is the final product. Select copper greedy bacteria detoxification to create good fermentation conditions; then use the extrusion method to achieve solid-liquid separation, and use NaOH solution to hydrolyze the lipids and proteins contained in the liquid substances, and then use trypsin for further hydrolysis treatment to make the hydrolysis more efficient Thoroughly; at the same time, after drying and pulverizing the extruded solid, put it into sulfuric acid solution for acid hydrolysis, treat it under the shear stress of electrorheological fluid, and then add cellulase for enzymatic hydrolysis treatment, with good effect and low energy consumption; the present invention Maximize the processing rate of raw materials, and finally obtain saccharified hydrolyzate rich in nutrients such as glucose, amino acids, small molecular chain lipids, etc., and obtain high glucose content for further fermentation, improving production efficiency .

Description

technical field [0001] The invention relates to a process for hydrolysis and saccharification of lotus seedlings, belonging to the technical field of biomass pretreatment. Background technique [0002] Neptera chinensis belongs to Amaranthaceae and the genus Lianzia, also known as philodendron philodendron, water peanut, and revolutionary grass. This grass often forms a single dominant community. The terrestrial type crowds out the normal growth of native plants and endangers the local biodiversity. , Competing with crops for sunlight, water, fertilizer and growth space in the farmland, resulting in reduced production and affecting farmland operations. At the same time, the growth space of native plants in the community is limited. The grass grows rapidly in the aquatic environment, covers waters, blocks waterways, affects freshwater aquaculture and farmland irrigation, and has become one of the world-recognized malignant weeds. Biolist". [0003] With the depletion of non...
