Dear Colleauges;

	Does anyone know the origin of E. coli DC2, a K-12 derivative that was originally 
derived from E. coli UB1005?  Was it obtained as a consequence of purposeful chemical
or radiation mutagenesis, or was it simply a spontaneous mutant?

	Responders are kindly asked to contacte me _directly_ at

Thanks in advance to all repliers,
