摘要

为了利用PCR DNA片段提高枯草芽孢杆菌马尔堡168的转化效率，我们在培养培养基中添加Mn2+，优化了适能细胞的制备。Mn2+的加入既促进了细胞生长，又增加了转化频率。此外，我们确定了两端同源序列的必要长度，从而通过双交叉重组实现实际充分的转化。

Improved transformation system of Bacillus subtilis competent cells using PCR DNA fragments as donor DNA.

To enhance the transformation efficiency of Bacillus subtilis Marburg 168 using PCR DNA fragments, we optimized the competent cell preparation by adding Mn2+ to the competence medium. This Mn2+ addition promoted both cell growth and increased transformation frequency. Moreover, we determined the necessary length of the homologous sequence on each end to achieve practically sufficient transformation through double crossover recombination.
