ultraviolet absorption data and thermal chromatography through a hydroxyapatite column revealed that nitrofurantoin treatment of v. cholerae strain ogawa 154 produced a maximal amount of 55 % reversibly bihelical dna at a nitrofurantoin dose of 120 micrograms/ml/h , which indicated the formation of inter-strand cross-links in dna .
