AI Technical Summary
Technical Problem
Existing xylitol fermentation methods have low xylitol yields and require harsh reaction conditions, making it difficult to achieve efficient resource conversion of agricultural and forestry waste.
Method used
A light-driven hybrid system was used to ferment agricultural and forestry waste. A light-driven biological hybrid system was constructed using photosensitizers. Photogenerated electrons were used to promote coenzyme regeneration and yeast energy metabolism, thereby increasing xylitol yield.
Benefits of technology
Under light conditions, the light-driven yeast fermentation method significantly improved xylitol yield by 4.71% to 33.28%, and achieved high-value resource utilization of agricultural and forestry waste.

Abstract
本发明公开了一种利用光驱动杂合体系发酵农林废弃物产木糖醇的方法，属于木糖醇发酵技术领域，包括以下步骤：农林废弃物的预处理，光驱生物杂合体系的构建以及光驱生物杂合体系发酵产木糖醇。具体的，采用两种方式构建光驱生物杂合体系，一为投加光敏剂到发酵体系中组成混合体系促进发酵(混合体发酵)，二为将光敏剂固载到微生物上形成光敏剂‑酵母菌杂化体进行光驱动木糖醇发酵(杂化体发酵)。本发明将光敏剂受光能激发产生具有还原力的光生电子的特点和非光合产木糖醇酵母菌特异性代谢的选择性优势相结合，可有效提高微生物的代谢能力，并且构建的光驱生物杂合体系生物相容性好，对菌体无毒害作用。能高效利用农林废弃物促进木糖醇的积累。
