title: Correlation between pigment production and amino acid requirements in Bacillus subtilis.
abstract: Several Bacillus subtilis W-23 auxotrophs were unable to produce wild-type pigment normally on minimal agars supplemented sufficiently for growth. This offers a reliable means for scoring genotypes.
