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.

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.

Abstract: The invention relates to a microbial process for the degradation of cyanuric acid in waste water containing cyanuric acid. The essential feature of the process is that a fungus of the Sporothrix genus, particularly a fungus of the Sporothrix schenkii variety is used for degrading the cyanuric acid. According to a variant of the process, it is possible to degrade, in addition to cyanuric acid, also any ammeline and ammelide present by using, besides a fungus of the Sporothrix genus, a second microorganism which is compatible with the fungus and which effects degradation of ammeline and ammelide to cyanuric acid. Waste water such as that accumulating in the commercial production of triazine herbicides can be purified by the process according to the invention.
