We constructed a cloning vector for use in the acidophilic heterotroph Acidiphilium facilis. The vector pAH1O1 (8.8kb) was constructed from a 6.1 kb restriction fragment of the Acidiphilium plasmid pAU1 and a pUC19 carrying a β-lactamase gene. The antibiotic resistance gene was efficiently expressed in A. facilis. Several factors which influenced the transformation efficiency were optimized, resulting in a transformation efficiency of up to 3 × 103 transformants per μg of plasmid DNA at a field strength of 10kV/cm with a 7.0ms pulse.
