A system of primers was designed on the basis of analysis of nucleotide sequences of the emoA gene encoding ethylenediaminetetraacetate (EDTA) monooxygenase, which are deposited in GenBank. This system of primers makes it possible to obtain emoA gene fragments approximately 750 bp long for bacterial destructors of EDTA. Polymerase chain reaction (PCR) of total DNA isolated from enrichment and pure cultures showed that this system can be effectively used for detecting the emoA gene in representatives of Alpha- and Gammaproteobacteria. Partial sequences of emoA genes of bacteria of the genera Chelativorans and Stenotrophomonas, which are able to degrade this pollutant, have been sequenced and deposited in GenBank.
