A highly efficient electroporation system for transformation of Bacillus licheniformis
- 228 Downloads
Transformation of intact cells of Bacillus licheniformis 5A24 with plasmids pLM6 (2.8 kb), pC194 (2.9 kb) and pCP49 (7.1 kb) by electroporation resulted in 1.5 × 106, 1.2 × 106 , and 5.2 × 104 transformants per μg DNA, respectively. Transformation was possible with plasmid DNA, which was religated after restriction endonuclease digestions. In addition, evidence is presented that indicates that B. licheniformis possesses DNA restriction and modification systems.
