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.
