Abstract
Colony productivities of 5 media (2 containing skim milk, 2 milk-free, and 1 synthetic) have been compared with that of the official (TGEM) medium, authorized by the American Public Health Association. The chief objective was to discover a suitable milk-free medium to replace the TGEM medium. Work on improving the milk-free media is being continued. The synthetic medium (selected amino acids, vitamins, purines, pyrimidines, mineral salts, glucose and agar) gave about 95 percent productivity of the TGEM medium. A synthetic medium has potential use as a reference productivity standard.Keywords
