Of these three only HQNO (10-50 microM) worked in E.coli
in my hands. I tried up to 0.1 mM rotenone, but to no avail. These
were wild-type strains, though.
You might want to try piercidin (sp?) and/or amytal. Amytal
(5 mM) was succesfully used by M. Eisenbach in E.coli. You'll need a
special permision to use it (it's a barbiturate).

Stationary-phase E.coli have cyanide-resistant respiration and a
bunch of other nice features. You will be better of starting with log-

Let me know, what exactly you're looking for. I'll have to dig
out of the snow and get to my desk...
