一株海藻糖酶生产菌及其应用
摘要：
本发明公开了一株海藻糖酶生产菌及其应用，属于工业微生物技术领域。本发明的大黄欧文菌C2，其特征在于，其分类学命名为大黄欧文菌Erwinia rhapontici，已于2018年11月21日保藏于中国普通微生物菌种保藏管理中心，保藏地址为北京市朝阳区北辰西路1号院3号，保藏编号CGMCC No.16760。本发明首次报道了一种产海藻糖酶的大黄欧文菌(Erwinia rhapontici)，并对其酶学性质进行研究。该菌株所产海藻糖酶的最适温度和pH分别为40℃和pH5，在酸性条件下具有较高活性和稳定性，在乙醇工业中应用前景广阔。
摘要（英）：

The invention discloses a trehalase production strain and application thereof and belongs to the technical field of industrial microorganisms. Erwinia rhapontici C2 provided by the invention is characterized in that the taxonomic name is Erwinia rhapontici and is preserved in China General Microbiological Culture Collection Center (CGMCC) on November 21, 2018, the preservation address is No. 3, No. 1 Yard, West Beichen Road, Chaoyang District, Beijing, and the preservation number is CGMCC No. 16760. The invention reports the Erwinia rhapontici for producing a trehalase for the first time and enzymatic properties of the Erwinia rhapontici are researched. The optimal temperature and pH (Potential of Hydrogen) of the trehalase produced by the strain are 40 DEG C and pH5 respectively; the trehalase has relatively high activity and stability under an acidic condition and has a wide application prospect in an ethanol industry.
