Abstract
Five broth media and two solid media were compared for their ability to quantitatively recover total coliform bacteria from chemically treated water. M-Endo LES and mT7 media were used in the membrane filter technique. Lauryl tryptose broth, lactose broth, presence-absence broth, lactose broth with twice the amount of lactose, and lauryl tryptose broth with twice the amount of sodium lauryl sulfate were used in the fermentation tube procedure. The differences in recovery were not significant for the five broth media and M-Endo LES agar. The M-Endo LES and mT7 media were not significantly different; however, the five broth media did yield significantly higher counts than mT7.
