Reduction of 4-Nitroquinoline 1-Oxide by Microörganisms

抄録

The ultraviolet absorption maximum of 4-nitroquinoline 1-oxide was shifted toward shorter wave length when the substance was added to the growing media of microorganisms. The investigation of this phenomenon revealed that the shift in ultraviolet absorption maxima is due to the reduction of nitro group at 4-position. It was also foundthat the reduction of N→Obond in 1-position occurs to a smaller extent.
