Fiv. wild plant species belonging to different families (Chenopodium album, Plantago major, Elytrigia elongata, Filipendula ulmaria and Nigella sativ.) widely spread in Russian Federation and the former USSR were ev.luated for their ability to inhibit growth of two important human food-borne pathogens (Escherichia coli O157:H7 and Listeria monocytogenes strain EGD-e) and eight plant pathogens (Alternaria alternata, Alternaria tenuissima, Bipolaris sorokiniana, Stagonospora nodorum, Fusarium solani, Fusarium oxysporum, Fusarium culmorum and Phytophtora infestans). To isolate biologically activ. compounds from seeds, a step-wise procedure including extraction with hexane, ethyl acetate, ethanol, and 10% acetic acid followed by rev.rsed-phase HPLC was dev.loped. Using disc-diffusion assay, the highest activ.ty against E. coli O157:H7 was observ.d with extracts from F. ulmaria (hexane and ethyl acetate extracts and the unbound RP-HPLC fraction) and P. major (ethyl acetate extract and the unbound RP-HPLC fraction);E. elongate (the unbound RP-HPLC fraction) was less activ.. The extracts from P. major and E. elongate (the unbound RP-HPLC fractions) were equally highly activ. against L. monocytogenes, while those of F. ulmaria (the unbound RP-HPLC fraction) and N. sativ. (hexane and ethyl acetate extracts) were less activ. against this pathogen. The dynamics of L. monocytogenes EGD-е and E. coli O157:H7 growth in the presence of two most potent extracts (RP-HPLC-unbound fractions of P. major and E. elongate and the hexane extract of F. ulmaria) was studied.

One of the methods used in practice for the purification of wastewater from v.getable-processing enterprises is biological method of aerobic purification. With the aim to increase air-tank capacity used in traditional systems of biochemical purification of wastewater, different ways effecting to the process of v.tal activ.ty of microorganisms of activ. sludge are applied. On the one hand, using the compositions of different salts and complex organic biogenous supplements prev.nts from the accumulation of some anions in the amounts exceeding the limited concentration, on the other hand- allows different groups of microorganisms to choose biogenous elements, which they assimilate easily and fully. It is known, that compounds of silicon and germanium can cause stimulating effects [1] to the organisms of activ. sludge. The goal of present studies is the intensification of biological processes of oxidation of organic contamination in wastewater by new bio-degradable chemical compounds or compositions on their basis, and by bio-sorbents.

Open Journal of Physical Chemistry 2015年第4期5卷 110-121页

The perov.kites with general formula ABX3 hav. been widely used as for materials with their unique properties (ferroelectric, piezoelectric, dielectric, catalytic and so on). Hybrid organolead halide perov.kites are a class of semiconductors with ABX3 (X = Cl, Br, and I) structures consisting of lead cations in 6-fold coordination (B site), surrounded by an octahedron of halide anions (X site, face centered) together with the organic components in 12-fold cub octahedral coordination. These hybrid perov.kites hav. a direct band gap, a large absorption coefficient as well as high charge carrier mobility that represent a v.ry attractiv. characteristic of cost-effectiv. solar cells. Basically, these crystals are inorganic solids of CaTiO3 type held together by bonds that are either ionic or partially ionic and partially cov.lent. In spite of the partially cov.lent character of the Ti-O bond, the system is modeled by a two-body central force interatomic potential (the form of the v.shishta and Rahman interatomic potential), which has been used successfully for many materials with a perov.kite structure. In the present work using molecular dynamics (MD) simulation method we inv.stigate the dynamical and structural behav.or of CaTiO3 perov.kite at normal pressure and temperature conditions. The MD calculations were performed on a system of 16,000 particles (3200Ca + 3200Ti + 96,00O), initially in an orthorhombic-Pbnm structure. The orthorhombic MD box had edges Lx = 53.4 Å, Ly = 53.4 Å and Lz = 61.12 Å, which prov.ded a density matching the experimental v.lue of ρ = 4 g/cm3. Starting with this structure and using proposed interatomic potentials the MD system stabilizes at room temperature in its initial configuration. The aim of the present study to explore the effect of potential function representations on structural equilibrium properties for the perov.kite models including hybrid halide ones outlined abov.. Concerning the perov.kite equilibrium state we
