AI Technical Summary
In existing technologies, the enzymatic hydrolysis efficiency of lignocellulose is low, phenolic compounds have an inhibitory effect on the microbial fermentation process, resulting in low lactic acid fermentation efficiency. Furthermore, traditional ionic liquids are costly and highly toxic, affecting subsequent fermentation processes.
Straw is pretreated with an enzyme-containing pretreatment agent combined with an ionic liquid. Lignin peroxidase and a photocatalytic hydrogen peroxide production catalyst are used to degrade straw by immobilized enzymes and ionic liquids, thereby reducing the activity of phenolic compounds and improving enzymatic hydrolysis efficiency.
It improves the sugar yield of straw-based sugar solutions, reduces the toxicity of phenolic compounds, increases lactic acid yield, and lowers production costs. Furthermore, the ionic liquid and enzymes can be reused repeatedly, making it suitable for industrial-scale circular production.
