the effect of sulfanilamide on the growth of broth cultures of eight species of luminous bacteria indicates that there is no regular relationship among the different organisms between the concentration of the drug that prevents growth , and that which prevents luminescence in the cells which develop in the presence of sulfanilamide . p-aminobenzoic acid ( pab ) antagonizes the sulfanilamide inhibition of growth in luminous bacteria , and the cultures that develop are luminous .
