EFFECT OF PENTAMIDINE ON THE GROWTH OFESCHERICHIA COLI

Abstract
The growth in simple medium of E. coli strain K-12 is inhibited by pentamidine. This inhibition is overcome by glutamic acid or a-ketoglutaric acid in a competitive manner. A "sparing" of glutamic acid in the suppression of inhibition occurs with combinations of isoleucine and valine. Transamination in dried cells between glutamic acid and a-keto valine is inhibited by pentamidine.
