Synthetic Media for Pleuropneumonialike Organisms.

Abstract

A synthetic medium is described which permits almost optimal growth of some strains of pleuropneumonialike organisms. The strains employed were found to vary in their nutritional requirements. Some strains did not require lipoprotein, some required the ash of peptone, while others failed to grow on synthetic media. Sn++ appears to have some nutritional role in the growth of these organisms. Amino acids appear to serve as the only energy source.
