I take it that you haven't found your mutant of choice yet. First a couple
questions and then a suggestion.
1) Are you sure that Aeromonas sobria has only one phosphatase? If there
are multiple phophatases that are active on LB/BCIP plates then the chances
of seeing a white is much lower.
2) Have you done a killing curve with your mutagenesis yet? This is a
handy thing to do in order get a handle on how hard you are hitting your
A realy good resource for your experiment is Jeffrey H. Miller's "A Short
Course in Bacterial Genetics" 1992. Cold Spring Harbor Laboratory Press.
ISBN 0-87969-349-5. Specifically, Experiment 3, Mutagenesis with EMS.
