, creD101Strain Comments:
- Transfers predominantly from PO129 but PO130 may also be present.
- thyA117-- Strains with this marker must have their medium supplemented with thymine (25ug/ml). This is true even for rich medium such as LB. Otherwise thymine starvation can lead to thymineless death.
- strR = streptomycin resist.
