Variations in the nucleic acid content of <i>Bact. lactis aerogenes</i> during the growth cycle

Abstract

Abstract During the growth cycle of Bact. lactis aerogenes in a medium containing glucose and inorganic salts the ratio RNA/DNA rises steeply to a maximum and declines. The variation is due in the main to the RNA. It depends on a complex set of factors affecting the environment, and is not primarily a question of the number of divisions undergone by the original inoculum.
