It has been previously shown that a selenium (Se) nanocomposite (NC) based on the natural polysaccharide arabinogalactan (AG) produced from Siberian larch wood (Larix sibirica Ledeb.), containing 0.000625% of Se, antibacterial properties against phytopathogens, such as Clavibacter sepedonicus, Pectobacterium carotovorum, and Phytophthora cactorum. The same concentration Se/AG NC stimulated growth development potato plants in vitro, well formation their roots, while Se did not accumulate tissues after plant treatment. However, to realize full potential agriculture for fighting phytopathogens with aim developing commercial nanopreparations, additional toxicological studies are needed fully address effects. In this study, assess environmental risk using NCs, it was applied number bacteria isolated soil (Escherichia coli, Bacillus cereus, B. megaterium), water (Micrococcus luteus, subtilis, Sarcina flava), activated sludge wastewater treatment facilities (Serratia marcescens, M. Pseudomonas aeruginosa). When studying activity 11 test cultures agar diffusion method, had toxic effect only at high concentrations range 40 mg/mL (1.68 Se) 0.625 (0.026 two types luteus waters Lake Baikal cereus obtained facilities. maximum diameter inhibition zone exposure different noted (water) E. coli (soil) − 26.3 20.3 mm, respectively. Thus, negative impact ecological niches registered concentrations, similar predicted wastewater, which demonstrates safety use agriculture.
