Strain Comments:

• The above is the description which we received with the strain. We do not know its derivation nor do we have a reference for it. A better description will be sent as soon as possible.
• thyA0-- 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.
• galP77::Tn10 was formerly called galP10::Tn10
• = tetracycline resistant
• Am = amber(UAG) mutation
• Const = constitutive
