..and if you know how many copies of the genome are swimming
around in your cells.
e.g. Churchward et al (1982) J Theor Biol 94, 651-70:
exponentially growing e. coli (in various minimal media) has 1.6
to 4.0 copies, depending on the growth rate.
since the original question was 'amount of DNA per CFU' you have
to know how many genomes are inside your bugs.
