Notes on various bacterial strains:

E. coli:

Strain	Description	Heritage	References
Dh5a
BW21578	rrnBT14 ΔlacZWJ16	BD792 via BW21342
BW22773	lacIq rrnBT14 ΔlacZWJ16 proC::Tn5-132;
BW27784
BW22786

Note on LacI satus of BW strains (copied from http://openwetware.org/wiki/E._coli_genotypes):

"We have now confirmed that BW25113, BW25141, and BW26434 are all lacI+, and not lacIq. We thank you for alerting us to the error with respect to BW26434. Apparently, the lacI region was restored to wild-type in a predecessor of BW25113.

As strains BW27784 and BW22786 were also constructed from BW25113, the former should also be LacI+.
