摘要
本文研究内容主要是对于云芝糖肽液体培养、HPGFC的测定,以筛选有效成分和糖肽含量相对较高的云芝菌株,并对培养基进行优化,在30L发酵罐当中进行扩充方法的实验。相关的结果显示,在30L发酵罐当中,发酵时间长达96小时之后,菌体的净重量可以达到每升24.29g,而糖肽的产量可以达到每升1.63g。并且,根据相关的测定发现,所提取的糖肽出峰时间与对照品的时间相对一致,蛋白质含量、含糖量与国家药品管理标准也相吻合,这就为云芝糖肽工业化的发酵提供了有力的基础支撑。本文主要对于云芝糖肽液体发酵条件及其提取工艺展开了探究。

Abstract
The research content of this paper is mainly for the determination of Yunzhi glycopeptide liquid culture and HPGFC, in order to screen Yunzhi strains with relatively high content of active ingredients and glycopeptides, optimize the medium, and expand the method in a 30L fermenter experiment of. Relevant results showed that in the 30L fermenter, after the fermentation time was as long as 96 hours, the net weight of the bacteria could reach 24.29g per liter, and the yield of glycopeptides could reach 1.63g per liter. In addition, according to relevant measurements, it was found that the peak time of the extracted glycopeptides was relatively consistent with the time of the reference substance, and the protein content and sugar content were also consistent with the national drug management standards, which provided the industrial fermentation of Yunzhi glycopeptides. strong foundation support. In this paper, the liquid fermentation conditions and extraction process of Yunzhi glycopeptides were mainly explored.
Key words: Yunzhi; glycopeptides; Liquid fermentation; Extraction process
