Method When 100 micrograms/ml erythromycin is added to nutrient agar plates, it is possible to obtain a 30-fold enrichment for cds mutants from a mutagen-treated stock, as judged by colony autoradiography. Using this approach researchers isolated 38 new cds mutants, nine of which are unable to grow at a culture pH greater than 8. Protein levels were calculated from the A550 of the culture
Comments In GN85 (cds+) at pH 6, the liponucleotides comprised about 0.04% of total phospholipids, or about a fifth of the size of the phosphatidic acid pool (See Table - link See BNID 104812, 104814
