CGSC Strain#: 7563
Strain Designation: DS112      Source of Strain: S. Rahuel-Clermont
Sex: F- Chromosomal Markers: λ^-, ΔgapA12::Cm, rph-1
Strain Comments:

• ΔgapA12::Cm-- : gap/epd deleted strains should be grown on minimal supplemented with casamino acids, Trp, Met, Thi, succinate + glycerol + antibiotic; they do not grow on LB or glucose media.
• rph-1-- is a 1 bp deletion that results in frameshift over last 15 codons and has polar effect on pyrE leading to suboptimal pyrimidine levels on minimal medium.(Jensen 1993 JBact.175:3401)
