F- Chromosomal Markers: leuB19
, deoC2Strain Comments:
- lacZ53(Am)-- is the Paris lac-Y14 amber.
- thyA36-- 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.
- Am = amber(UAG) mutation
- strR = streptomycin resist.
