strain selection

strain selection

the means of obtaining desired STRAINS, such as desired MUTANTS (from a MUTATION programme) or desired recombinant clones (formed by GENETIC ENGINEERING), by distinguishing them generally on the basis of one or more specific PHENOTYPES. This may involve the use of a SELECTIVE MEDIUM or a DIFFERENTIAL MEDIUM.
