title: New maltose Blu mutations in Escherichia coli K-12.
abstract: Mutations in the genes pgi, pfkA, and ptsG resulted in a maltose Blu phenotype in Escherichia coli K-12, bringing the number of known Blu alleles to six. The Blu phenotype, as visualized by staining with iodine vapor, is a convenient mutant isolation technique.
