F- Chromosomal Markers: fhuA53
, lacY1 or Δ(cod-lacI)6
, hsdS3Strain Comments:
- dapD8-- Strains with this mutation require 100ug/ml diaminopimelic acid even when grown on LB
- ΔthyA57-- 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.
