Biodegradation of s-triazine xenobiotics
Biodegradation of xenobiotic compounds is examined with s-triazines as an example and with biological treatment of wastewater containing striazines as an aim. s-Triazines have been termed recalcitrant, but examination of the literature indicates that a potential for biodegradation exists. Ni t rogenl imi ted enr ichment cultures yield organisms able to degrade by-products of the industrial synt...
متن کاملEnzymatic degradation of chlorodiamino-s-triazine.
2-Chloro-4,6-diamino-s-triazine (CAAT) is a metabolite of atrazine biodegradation in soils. Atrazine chlorohydrolase (AtzA) catalyzes the dechlorination of atrazine but is unreactive with CAAT. In this study, melamine deaminase (TriA), which is 98% identical to AtzA, catalyzed deamination of CAAT to produce 2-chloro-4-amino-6-hydroxy-s-triazine (CAOT). CAOT underwent dechlorination via hydroxya...
متن کاملBiodegradation of an s-triazine herbicide, simazine
Two types of simazine-degrading microorganisms were isolated from soil samples where the herbicide had been spread with the enrichment culture using simazine as the sole carbon and nitrogen source. A fungal strain, DS6F, identified as Penicillium steckii, is the first simazine-degrading fungus ever reported. Ž Simazine was gradually degraded by P. steckii DS6F in the mineral medium containing s...
متن کاملNitrogen-14 NQR in s-Triazine Derivatives*
Within a study of the temperature dependence of NQR frequencies in some s-triazine derivatives [1], resonance frequencies at 4.2 K were determined in melamine, cyanuric acid, and cyanuric chloride. New lines, which were not reported so far, were detected in two of these compounds. In melamine, nine more lines were found as already described in [4], In cyanuric chloride, two more lines were foun...
متن کاملPrediction of s-triazine components lipophilicity of total herbicides
A liquid chromatography method has been developed and validated for the determination of mathematical models for prediction of the lipophilicity of s-triazine compounds. Correlation between retention factors, RM 0 , of several s-triazine derivatives and their physico-chemical and structural properties has been studied by TLC on silica gel impregnated with paraffin oil. The research in this pape...
