It is discovered that the antimicrobial effect of red azo dye Prontosil was caused by the reductively cleaved (azo reduction) product sulfanilamide, and the significance of azo reduction is revealed.
Effects of nisin on growth of bacteria attached to meat
It is disclosed that nisin delays the growth of some gram-positive bacteria attached to meat, however, nisin alone may not be sufficient to prevent meat spoilage because of the presence of gram-negative and other nisin-resistant gram- positive bacteria.
Mutagenicity studies of benzidine and its analogs: structure-activity relationships.
Physicochemical parameters of these compounds including oxidation potentials, the energy difference between the lowest unoccupied molecular orbital and the highest occupied molecular orbital, ionization potentialS, dipole moment, relative partition coefficient, and basicity did not correlate with their bacterial mutagenic activities.

Possible roles of excess tryptophan metabolites in cancer
It could be concluded that tryptophan metabolites play a complementary role in promoting carcinogenesis along with carcinogens like aflatoxin, CCl4,2‐acetylaminofluorene, 4‐aminobiphenyl, 2‐naphthylamine, or N‐[4‐(5‐nitro‐2‐furyl)−2‐thiazolyl] formamide.
