Comments:
- pKD46 is more efficient than pKD20 for making gene disruptions. pKD46 sequence: GenBank AY048746. See also pKD78(CmR) and pKD119(TetR).
- The ara and rha deletions were published as Δ rhaBAD_LD78 and Δ araBAD_AH33
- This strain also contains the conjugative pB15 plasmid from PET297
- This strain should be grown on rich media with ampicillin (100 ug/ml at 30 C).
