Adding sodium pyruvate to 1/2 strength PYG medium yielded higher plate counts for a river bacterial community. Maximal counts were obtained when 0.15g liter-1 of sodium pyruvate was added to the medium for both river water and epilithon samples. The degree of magnification of the plate counts on the medium supplemented with sodium pyruvate varied depending on the source of the sample. The findings suggested that the variations in magnification reveal aspects of physiological activities of microbial communities in river environments.
