  • Process for the degradation of s-triazine derivatives in aqueous solutions
    Patent number: 4745064
    Abstract: The invention relates to a novel microorganism of the genus Rhodococcus, to the use thereof in a process for the microbiological degradation of amino-s-triazines and cyanuric acid in wastewaters, as well as to a process for the microbiological degradation of s-triazine derivatives to biomass or to degradation products such as NH.sup.30.sub.4 and/or chloride, which comprises the combined use of said microorganism with Pseudomonas spp.

  • Process for decomposing 2,4-dihydroxy-6-amino-s-triazine derivatives
    Patent number: 4415658
    Abstract: The invention relates to a process for decomposing 2,4-dihydroxy-6-amino-s-triazine derivatives in effluents. The essential feature of the process is that the effluent is brought into contact under aerobic conditions with either of the strains Pseudomonas sp. NRRL B-12228 or Pseudomonas sp. NRRL B-12229. It is likewise possible according to one variant of the process to convert 2-hydroxy-4,6-diamino-s-triazine derivatives present into 2,4-dihydroxy-6-amino-s-triazine derivatives by bringing the effluent into contact with Pseudomonas sp. NRRL B-12227.
