I remember that one, but don't have the reference. Seems to me it was a pretty
old technique, and that might be the reason you can't find it. It might also be
in Miller, J. H. 1972. Experiments in molecular genetics. Did you check there?
Maybe it's referenced in the more recent paper for selecting tetracycline
sensitive bacteria:
@article{Maloy1981,
author = "S. R. Maloy
and W. D. Nunn",
title = "Selection for loss of tetracycline resistance
by {{\em Escherichia coli}}",
journal = "J. Bacteriol.",
volume = "145",
pages = "1110-1111",
year = "1981"}
Sorry I can't be more specific.
I hope those clues get you to the right place.
