Polyethylene glycol-treated protoplasts of B. subtilis can be transformed by plasmid DNA at very high frequencies (Chang and Cohen 1979). From analysis of plasmid mediated transformation of transformation-deficient mutants it appeared that mutants, reduced in the transformation by plasmid DNA in the
A highly efficient method for transformation of Bacillus subtilis by plasmid DNA is reported. The procedure, which involves polyethylene glycol-induced DNA uptake by protoplasts and subsequent regeneration of the bacterial cell wall, yields up to 80% transformants with an efficiency of 4 x 10(7) tra
