Abstract
The effect of boric acid in a peptone-lactose broth on the growth of cultures of the genera Escherichia and Aerobacter is reported. The pH of the media caused little differences in growth. In the medium, containing 0.325% boric acid, 59% of the Aerobac-ter cultures, 92.5% of the Escherichia Cultures, and 35.5% of the Citrobacter cultures produced gas. In the solid media a greater concn. of boric acid was required to prevent growth than in liquid.Keywords
