Sažetak
Aims: To characterize an atrazine-degrading bacterial community enriched from the wastewater of a herbicide factory. Methods and Results: The community mineralized 81.4+/-1.9% of [14C-ring]atrazine and 31.0+/-1.8% of [14C-ethyl]atrazine within 6-days of batch cultivation in mineral salts medium containing atrazine as the sole nitrogen source. Degradation activity of the community toward different chloro- and methylthio-substituted s-triazine compounds was also demonstrated. Restriction analysis of amplified 16S rDNA (ARDRA) revealed high diversity of bacterial populations forming the community, with Pseudomonas species dominating in the clone library. Atrazine-degrading genetic potential of the community determined by PCR revealed the presence of trzN, atzB, atzC and trzD genes. The trzN, atzB, atzC genes were shown to be located on a plasmid of 322 kb. Quantitative PCR showed that relative abundances of atzB, atzC and trzD genes were approx. 100-fold lower than 16S rDNA. Conclusions: The enriched community represents a complex bacterial association expressing substantial atrazine mineralizing activity and a broad specificity toward a range of s-triazine compounds. Significance and Impact of the Study: Our study is beginning to yield insights into the richness, genetic potential and density of functional atrazine-mineralizing community that could be potential bioaugmentation agent for improving biotransformation processes in wastewaters bearing different s-triazine compounds.
