The usual method of counting heterotrophic bacteria in water is by the poured plate method with Yeast Extract Agar. Separate counts are made of those aerobic mesophilic organisms which form visible colonies in this medium after 24 hours incubation at 37°C and those which form colonies after three days incubation at 22°C. The two methods give different results2.
The organisms growing under these conditions comprise bacteria, yeasts, and molds.
