Cell-to-Cell Natural Transformation Mediated Efficient Plasmid Transfer Between Bacillus Species

Area of Science:

• Microbiology
• Bacterial Genetics
• Synthetic Biology

Background:

• Horizontal gene transfer (HGT) drives bacterial evolution and genetic diversity.
• Bacillus subtilis is a model organism for HGT studies and has industrial applications.
• Existing plasmid transfer methods have limitations in efficiency and scope.

Purpose of the Study:

• To characterize a novel, efficient method for plasmid transfer in Bacillus subtilis.
• To evaluate the applicability of this method across different Bacillus species and natural isolates.

Main Methods:

• Co-culturing donor and recipient Bacillus subtilis cells under antibiotic stress.
• Comparing the efficiency of the novel method (CTCNT-P) with traditional methods like Spizizen medium and electroporation.
• Testing CTCNT-P on wild Bacillus isolates and related species (B. amyloliquefaciens, B. licheniformis, B. thuringiensis).

Main Results:

• The novel Cell-to-Cell Natural Transformation for Plasmid Transfer (CTCNT-P) method significantly increases plasmid transfer efficiency in B. subtilis.
• CTCNT-P is effective for plasmid transformation in wild B. subtilis strains and other Bacillus species.
• The method is more efficient than traditional transformation techniques.

Conclusions:

• CTCNT-P offers a simple and highly efficient approach for plasmid transfer in Bacillus species.
• This method has strong potential for industrial applications, including synthetic biology and biocontrol agent development.
• CTCNT-P facilitates genetic modification of wild Bacillus strains effectively.
