Bacteria-destructors of persistent organic pollutants - phthalic acid esters, as a basis for the creation of new ecobiotechnology

In this article we analyzed the problem of microbial degradation of environmentally dangerous pollutants by the example of dibutyl phthalate as one of the most common pollutants, including waste potash production. From the samples of technogenic mineral formations, soil and ground of a salt-mining plant JSC "Uralkali" (Berezniki, Solikamsk, Perm krai) there were isolated active halotolerant strains-destructors of dibutyl phthalate being promising for creation a biotechnology based on microbial degradation of toxicants. Following a phylogenetic analysis of the isolated bacteria the strains-destructors were assigned to the genera Rhodococcus, Arthrobacter, Dietzia, Bacillus, Exiguobacterium, Halomonas and Pseudomonas.
