  1. aThe restriction sites are underlined and may differ in sequence from the template genome of Veith et. al.[48].
  2. bThe primer is complement to the genome of Veith et. al.[48].
  3. cThe primer is complement to the SpR cassette of pMAD_SpR.
  4. dThe gerA fragment amplified contains a sequence 151 bp upstream of gerAA, gerAA, gerAB, gerAC and 177 bp downstream of gerAC relative to the genome of Veith et. al.[48].
  5. eThe primer is complement to the pHT315 vector.
