title: Construction of shuttle vectors useful for transforming Clostridium acetobutylicum.
abstract: Plasmids pIM13, pT127 and pBC16 delta 1, introduced by transformation into Clostridium acetobutylicum N1-4081, were shown to replicate in, and to confer antibiotic resistance upon this new host. Recombinant plasmids were constructed by inserting erythromycin-resistant plasmid pIM13 into the unique ClaI site of pBR322 or by ligating a tetracycline-resistant determinant of plasmid pT127 to HindIII-linearized pIM13. The hybrid plasmids replicated and expressed erythromycin resistance in C. acetobutylicum strain N1-4081 and in Escherichia coli or Bacillus subtilis, indicating that they might be useful as shuttle vectors for transferring genes between these strains. The efficiency and stability of different replicons in C. acetobutylicum were compared.
