Composition for solid preservation of enterococcus faecium and preservation method thereof

The invention belongs to the field of microorganisms, and particularly relates to a composition for solid preservation of enterococcus faecium and a preservation method thereof. A carrier used in the method is a medical stone-chitosan composite adsorbent, a protective agent is sodium glutamate and lactose, the moisture content of the bacterial powder is lower than 1%, the bacterial powder prepared through the method is high in bacterial content, the survival rate reaches 80% or above after the bacterial powder is stored for one year at the normal temperature, and the problem that enterococcus faecium fermentation liquor is difficult to preserve is solved. Compared with the prior art, the composition has the characteristics of low cost, easiness in operation and outstanding preservation effect. 本发明属于微生物领域，具体涉及一种屎肠球菌固体保藏用组合物及保藏方法。该方法所用到的载体为麦饭石-壳聚糖复合吸附剂，保护剂为谷氨酸钠和乳糖，菌粉水分含量低于1%，利用该方法制备的菌粉含菌量高，常温储藏1年，存活率达到80%以上，解决了屎肠球菌发酵液较难保存的问题。与其他技术相比，具有成本低、易操作、保藏效果突出的特点。
