thiE1Strain Comments: - leuB6(Am)-- Suppressed by serU suppressor (supH)
- galT23-- : This is the standard gal6 of Morse & Lederberg.
- thyA710-- 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.
