Study of Biological Properties of Effective Pesticides Destructor Pseudomonas Putida P2

Abstract

A promising approach for remediation of contaminated soils is the use of biological products based on microorganisms-destructors. Of particular interest are the strains that can decompose several types of pollutants. Potential strains-destructors should be not only effective but also adapted for certain soil and climatic conditions. In addition, when introducing a significant amount of biological agents into the ecosystem, the lack of toxicological and pathogenic effects on plants, animals, and humans is particularly important. The object of the study is the destructor strain of sim-triazine herbicide of prometrin Pseudomonas putida P2. The study explores the ability of strain to use various pesticides as the only carbon source, the effect of bacterial culture on seed germination, biotesting of strain on toxicity using earthworms. Besides, the study presents the phytopathogenic factors and enzymes causing bacteria invasiveness into animals and humans. The determination of dehydrogenase activity of prometrin destructor strain shows that this strain can also use active ingredients of pesticide malathion, HCH, and 4,4-DDT as only sole carbon source. It is also established that the studied strain Pseudomonas putida P2 increases the germination of seeds of the variety Saratovskaya 70 and carrots of the variety Samson and does not possess pathogenicity factors. The strain biotesting on the earthworms revealed no acute toxicity of the culture. The analysis of data obtained from the model pollution shows that the introduction of the destructor of Prometrium Pseudomonas putida P2 into the soil can create favorable conditions for vital activity and reproduction of earthworms.
