摘要
为降低雪茄烟叶中淀粉和纤维素含量,减少雪茄烟叶中的苦味,改善烟叶品质,从发酵雪茄烟叶中分离纯化得到18株细菌菌株,通过对菌株的性质测定,选出两种能够降解淀粉和纤维素的菌株SN-1与SN-2,经鉴定该菌株分别为阿尔莱特葡萄球菌(Staphylococcus arlettae)和乳酸芽孢杆菌(Paenibacillus lactis),并且筛选出最优生长条件分别为30℃、pH为6、碳源为蔗糖、氮源为胰蛋白胨和35℃、pH为6、碳源为蔗糖、氮源为胰蛋白胨。
In order to reduce the content of starch and cellulose in cigar tobacco leaves, reduce the bitterness in cigar tobacco leaves and improve the quality of tobacco leaves, 18 bacterial strains were isolated from the surface of cigar tobacco leaves. Two strains, SN-1 and SN-2, which can degrade starch and cellulose, were screened through property identification. The two strains were identified as Staphylococcus arlettae and Paenibacillus lactis. The optimal growth conditions for SN-1 were 30˚C, pH 6, carbon source was sucrose and nitrogen source was tryptone, while the optimal growth conditions for SN-2 were 35˚C, pH 6, carbon source was sucrose and nitrogen source was tryptone.
