Abstract

The bioaugmantation effect of bacterial strains on plant development in organochlorine pesticides (OCP) polluted soil has been in the focus of attention, however there is little information about Comamonas testosteroni strains influence. The investigation was performed by classic methods. The results of the research showed that Comamonas testosteroni UCM B-400 and B-401has a high destroying potential to xenobiotics in the soil, and also has a positive effect on plant development. The tomato plants ability to develop under conditions with Comamonas testosteroni UCM B-400 and B-401 bioaugmentation in HCB - contaminated and uncontaminated soil were studied. Comamonas testosteroni UCM B-400 and B-401 promoted the increasing of photosynthetic activity, biometric parametrs and increase the resistance to phytopathogens, such as Clavibacter michiganensis subs. michiganensis UCM Ас-629 (up to 36%) and Alternaria alternata UCM F-16866 (up to 32%). Comamonas testosteroni UCM B-400 and B-401 can be used as an inoculant to improve plant development conditions in HCB load soils.
