提取细菌基因组dna除了CTAB⼀NaCl 法之外还有其他方法吗？谢谢！

有，用试剂盒。
独特的结合液/蛋白酶K迅速裂解细胞和灭活细胞内核酸酶，然后基因组DNA在高离序盐状态下选择性吸附于离心柱内硅基质膜， 再通过一系列快速的漂洗－离心的步骤，抑制物去除液和漂洗液将细胞代谢物，蛋白等杂质去除， 最后低盐的洗脱缓冲液将纯净基因组DNA从硅基质膜上洗脱。

特点：
1.离心吸附柱内硅基质膜全部采用进口世界著名公司特制吸附膜，柱与柱之间吸附量差异极小，可重复性好。克服了国产试剂盒膜质量不稳定的弊端。
2.不需要使用有毒的苯酚等试剂，也不需要乙醇沉淀等步骤。
3.快速，简捷，单个样品操作一般可在30分钟内完成。
4.多次柱漂洗确保高纯度，OD260/OD280典型的比值达1.7～1.9，长度可达30kb -50kb，可直接用于PCR，Southern-blot和各种酶切反应。
