  • Method for eliminating a nitrogenated heterocyclic, or aromatic, compound in an effluent
    Patent number: 6582952
    Abstract: This invention relates to a method for the removal of a nitrogen containing heterocyclic or aromatic compound, comprising at least one nitro group, in an effluent by the conversion of said, at least one nitro group into an amine group by means of a reducing agent. The reducing agent can be hydrogen in the presence of Pd/C or a micro-organism. This invention also relates to a method for the synthesis of 5-amino-1,2,4-triazole-3-one from 5-nitro-1,2,4-triazole-3-one by said method of conversion, that allows one to achieve synthesis yields greater than 80%. This invention also relates to a colony of the type Bacillus licheniformis capable of converting one or more nitro groups of nitrogen containing heterocyclic compounds into one or more amine groups. This colony has been filed in the CNCM, held by the Pasteur Institute, under the number I-1915.
