Biological treatment specific for an industrial wastewater containing s-triazines

Mixed cultures of bacteria grew in medium containing real s-triazine wastes as nitrogen source. About 80% of the s-triazine waste could be degraded as determined by HPLC and by measurements of dissolved nitrogen. The culture required an added carbon source in order to degrade s-triazines. A temperature optimum near 40 degrees C was observed and a salt concentration above about 4% markedly retarded growth and the degradation of s-triazines. This system was examined as a biological treatment for wastes from syntheses of s-triazines.
