High Efficiency Transformation ofBacillus brevisby Electroporation

Various conditions in the Bacillus brevis transformation by electroporation were investigated to increase the efficiency. Competent cell volume and presence of polyethylene glycol 6000 and single stranded DNA on pulsing were critical for the efficiency. As a result, we established the improved method by which 10(7)-10(8) transformants/microgram plasmid DNA could be obtained.
