Popis: Having noted that different lots of the same brand of milk plating agar showed considerable irregularity in colony counts of the same samples of milk, the authors devised a reproducable synthetic medium in dry form which might serve as a Reference Standard against which different lots of peptone media could be evaluated. Milk samples plated in this synthetic medium yielded colony counts comparable to those obtained in samples of the TGEM medium of two different manufacturers provided only that plates containing the synthetic medium were incubated longer to allow for the somewhat slower development of the colonies.
