[Plasmid transformation of Bacillus cereus protoplasts].
The process of polyethyleneglycol-induced plasmid transformation of Bacillus cereus protoplasts was studied. Plasmid transfer into Bacillus cereus strains was demonstrated with the frequencies 1.3.10(1)-1.6.10(2) transformants per 1 mkg of plasmid DNA. The plasmids transferred are stably inherited by Bacillus cereus cells causing tetracycline resistance (pBC16) or kanamycin resistance (pUB110 and pBD64). The proposed method can be used for construction of Bacillus cereus strains having the plasmid determined characteristics.
