title: Electroporation-mediated transformation of Aeromonas hydrophila.
abstract: A strain of Aeromonas hydrophila producing copolyesters of 3-hydroxybutyrate and 3-hydroxyhexanoate, abbreviated as PHBHHx, was successfully transformed by electroporation. The plasmid used was a broad host range plasmid pBBR1MCS. Electroporation conditions were varied systemically to develop an electroporation protocol. The optimal yield of transformant was approximately 4x10(2) CFU/microg DNA at 12.5 kV/cm and 1000 Omega, resulting in a time constant of approximately 5 ms. The A. hydrophila transformants expressed plasmid-encoded resistance to chloromphenicol. Plasmid DNA in the A. hydrophila transformant was stably maintained. This is the first report of transformation of bacteria A. hydrophila.
