Strain Designation: WA834      Source of Strain: W. Arber
Other Designations: B834
Other Designations: AC5612
Sex: F- Chromosomal Markers: Δ(ompT-nfrA)885, Δ(galM-ybhJ)884, Δ46, met-100, [mal⁺]_K-12(λ^S), hsdS10
Strain Comments:

• Δ(ompT-nfrA)885-- This deletions actually spans from distal region of the DLP12 prophage to an Rhs element just downstream of nfrA in the E. coli B genome. Actual genes deleted are appY, ompT, envY, ybcH, and nfrA.
• Δ(galM-ybhJ)884-- Deletion from base 769,048 to 786,294 in the REL606 genome and includes the following genes: galMKTE, modFE, acrZ, modABC, ybhA, pgl, ybhD, ybhH, ybhI, and ybhJ
• Δ46-- : cured of defective P2-like prophage found in wildtype E.coli B.
• [mal⁺]_K-12(λ^S)-- The malK, lamB, malM region was transduced in from E. coli K-12.
• Δ(galM-ybhJ)884 was formerly called
• LamS = Lambda sensitive
