We have in our laboratory two strains of Escherichia coli with the following genotypes:
Strain A: ara- met- ser- pyr- lys-
Strain B: ara+ met+ ser+ pyr+ lys+
[ara- = inability to use the sugar arabinose; met-, ser-, pyr-, lys- = inability to synthesize methionine, serine, pyrimidines, and lysine]
What kind of culture media and supplements is necessary to add to the culture plates to select ara+ met+ recombinants after a mating between strains A and B?
