Mikroorganismen und Verfahren zur biologischen Entfernung von Nitratderivaten

摘要

Procedure for the biological removal of nitrated derivatives. The removal of 2,4-DNT, 2,6-DNT and TNT contained in industrial effluents, water and soil polluted with said compounds may be carried out biologically by inoculating the effluents and soil to be treated with a culture of microorganisms capable of degrading 2,4-DNT, 2,6-DNT and TNT. The bacteria belonging to the genus Pseudomonas that are capable of utilizing said compounds as a source of C and/or N, thereby inducing their removal, have been isolated. This process can be applied to the removal of 2,4-DNT, 2,6-DNT and TNT contained in polluted industrial effluents, water and soil, as well as to the destruction of excess TNT from arsenals and plants, thereby providing an effective solution to the environmental problem associated with the treatment of said pollutants.
