Аннотация: The significant growth in applications of silver nanoparticles across -various branches of industry as well as in consumer products has caused concerns that nanosilver may have a toxic effect on the environment and human health and may have implications for eco-terorism. This paper presents research on antimicrobial effects of silver nanoparticles. We studied the cytotoxicity of silver nanoparticles via an MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium-bromid) assay that measures cell activity through the mitochondrial cleavage of a molecule that exhibits a change of colour that can be measured spectrophotometrically. NIH-3T3 (Swiss mouse embryo), HEP-G2 (human hepatocellular carcinoma), A-549 (human lung carcinoma), PC-12 (rat adrenal pheochromocytoma), and Colo-320 (human colon adenocarcinoma) cells were chosen in order to study different possible absorption paths of nanoparticles into the organism and various areas of particle accumulation in the body. The obtained MTT test results have shown that silver nanoparticles with concentrations of ∼1-10 ppm entering the body from air or liquid suspensions can present a potential risk to human health. © Springer Science+Business Media B.V. 2011.

Аннотация: Antimicrobial and antifungal properties of silver nanoparticles, silver ions, acrylate paint and cotton fabric impregnated with Ag nanoparticles were assessed against Escherichia coli (Gram-negative bacterium); Staphylococcus aureus and Bacillus subtilis (Gram-positive bacteria); Aspergillus niger, Aureobasidium pullulans and Penicillium phoeniceum (cosmopolitan saprotrophic fungi). The silver ions used in the bacterial susceptibility tests were released from pure silver electrodes using a 12 V battery-operated direct current generator. The water-based silver colloidal solution was obtained by electroreduction of silver ions in water. Nanosilver was less effective against E. coli, S. aureus, B. subtilis and P. phoeniceum compared to silver ions. However silver nanoparticles have prolonged bactericidal effect as a result of continuous release of Ag ions in sufficient concentration and thus nanoparticles can be more suitable in some bactericidal applications. The synthesized silver nanoparticles added to water paints or cotton fabrics have demonstrated a pronounced antibacterial and antifungal effect. В© 2011 Springer Science+Business Media B.V.

Аннотация: The minimum inhibitory concentrations (MICs) assays conducted for E. coli, S. aureus, B. subtilis and P. phoeniceum have shown that the antimicrobial activity of silver ions was superior to that of silver nanoparticles. As silver nanoparticles can be more suitable in some bactericidal applications than silver ions, the efficacy of nanosilver as an antimicrobial agent against a range of microbes on the surface of water paints and cotton fabrics has been studied. The cytotoxicity of silver nanoparticles has been studied using NIH-3T3, HEP-G2, A-549, PC-12, and Colo-320 cells via the MTT ((3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium-bromid) test. The MTT test results obtained have shown that silver nanoparticles in concentrations of ~1-10 ppm entering the body from air or liquid suspensions can present a potential risk to human health. However, silver nanoparticles as a commercially viable addition to be used in paint and textile industry are unlikely to present a direct health risk. © 2010 Nova Science Publishers, Inc.

Аннотация: Оценена антимикробная активность летучих соединений хвои 23-летних клонов <i>Pinus sylvestris</i> L. методом «опарения» штриховых посевов микробных культур в чашках Петри. Исследования проведены 18 и 26 июля 2011 г. на трех тест-объектах - грамположительных бактериях <i>Staphylococcus epidermidis</i>, грамотрицательных бактериях <i>Esсherichia coli</i> и дрожжеподобных грибах <i>Candida albicans</i>. Оценка антимикробного действия сосны проводилась в сравнении с контролем по шкале фитонцидной активности в баллах от 0 (отсутствие эффекта) до 4 (сильный эффект). Средний балл фитонцидной активности клонов по отношению к отдельным тест-системам варьировал в пределах 0.00-3.00. Выявлены слабая дифференциация клонов сосны к <i>Staphylococcus epidermidis</i> и отсутствие достоверных межклоновых различий по воздействию эфирных масел сосны на остальные микробные тест-объекты. Частота парных сравнений, в которых обнаружены достоверные различия между клонами, составляет менее 5 % для S. epidermidis и около 1.5 % для всех тест-микробов. Наряду с этим прослеживались высокодостоверные эффекты времени проведения тестов (календарной даты), вида тест-объекта («патогена») и взаимодействия «дата тестирования - патогены» и «дата тестирования - клоны», на которые в 3-факторном дисперсионном анализе приходится около 23, 33 и 15 % соответственно. Наиболее вероятными причинами этого являются динамика состава летучих соединений хвои и взаимодействие генотип - среда, что должно стать объектом более пристальных исследований. Очень важным в этой связи является вопрос о сезоне, который оптимален для надежного выявления генотипов сосны, отличающихся максимальной фитонцидностью. Выявлена отрицательная межклоновая (генотипическая) корреляция между фитонцидностью сосны к <i>S. epidermidis</i> и к <i>C. albicans</i>. Возможно, это обусловлено обратно пропорциональной зависимостью между содержанием определенных компонентов в эфирных маслах, которые отвечают за ингибирование различных патогенных организмов. При анализе генетических особенностей протестированных клонов выделяются их совокупности, достоверно различающиеся, с одной стороны, по фитонцидности к стафилококку <i>S. epidermidis</i>, с другой - по индивидуальной гетерозиготности аллозимных локусов. Такого рода дифференциация генотипов отмечена впервые и также может быть в фокусе дальнейших исследований.
Streak inoculation of microbial test-cultures was treated with volatile emissions of needles of 23-years clones of <i>Pinus sylvestris</i> L. The study was conducted in July 2011 on three test-objects - gram-positive bacteria <i>Staphyllococcusepidermidis</i>, gram-negative bacteria <i>Esсherichia coli</i> and yeast-like fungi <i>Candida albicans</i>. Antimicrobial effect of pine volatile emissions was assessed in comparison with the control on 0 (absence of the effect) - 4 (strong effect) scale of antimicrobial activity. The mean marks of antimicrobial activity of clones, calculated in relation to separate test-systems, were within the limits of 0.00-3.00. The weak differentiation of pine clones to <i>S. epidermidis</i> is revealed. Frequency of pair comparisons in which statistically significant differences between clones was found to be less than 5 % for <i>S. epidermidis</i> and about 1.5 % for all the test-microbes. Alongside with it significant effects of the time of testing (calendar dates), a microbial species («pathogens») and interactions «date of testing-pathogens» and «date of testing-clones» were revealed: in ANOVA their effects amounted to nearly 23, 33 and 15 % of the total dispersion accordingly. The most probable reasons for it are dynamics of structure of essential oils and «genotype-environment» interaction that should become object of future research. In this connection, an important question is what is the season that is optimum for reliable revealing of the pine genotypes with maximal antimicrobial activity? Negative between-clones (between-genotypes) correlations between antimicrobial activity to <i>S. epidermidis</i> and to <i>C. albicans</i> are revealed. It is probably caused by inversely proportional dependence between concentrations of the components in essential oils, which are responsible for inhibition of various pathogenic organisms. The sample of investigated clones was divided into two sub-samples that sufficiently differed by the levels of both antimicrobial activity to <i>S. epidermidis</i> and individual heterozygosity of allozyme's loci. Such differentiation of genotypes is noted for the first time, and can be in focus of further studies.

Аннотация: In vitro cultivation of embryogenic cultures of Siberian larch on AI medium supplemented with different concentrations of antimicrobial peptides of two Trichoderma species, T.citrinoviride (strain TYVI 4/11) and T. viride (strain 346), has been performed to achieve a direct antimicrobial effect and initiate the mechanisms of induced resistance (regulatory function of embryogenic cultures) as well as to study the morphogenesis and growth activity of regenerant plants. The experiment was arranged using four cell lines, CL4, CL5, CL6, and CL12, differing in their embryogenic activity. The effect of treatment of cell cultures with Trichoderma peptides was manifested via significant growth stimulation of proliferating embryogenic cell lines, root growth stimulation, and formation of callus excrescences on regenerant plants. No difference between the treated and untreated variants was observed in seedlings. Conceivably, such peptide treatment may provide an increased immunity of soil-grown seedlings in forest nurseries. Study of the effect of biocontrol strains' use in a plantation reforestation to stimulate the growth and development of calluses and embryos and to obtain disease-resistant regenerant plants of conifer species will provide the development of a clonal silviculture, a new trend that recently appeared abroad (Park 2002, 2014).

Аннотация: By the method of exhaustive hydroparodistillation, essential oil was obtained from Siberian pine (Pinus sibirica Du Tour) and Siberian fir (Abies sibirica Ledeb.), growing on the territory of the Krasnoyarsk territory. Separate fractions of oil were obtained: the first one after 45 min from the beginning of distillation, the second - after 2 hours, the third - after 5 hours, the fourth-after 10 hours, the fifth fraction was collected after the end of hydrodistillation. The antimicrobial activity of separate fractions of essential oil of P. sibirica and A. sibirica was studied against strains of opportunistic microorganisms: Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus 209p, Micrococcus luteus, Acinetobacter baumanii, Candida albicans. The performed studies showed that all the studied samples of essential oils showed either bactericidal or bacteriostatic activity against the strains of microorganisms taken in the experiment, except Pseudomonas aeruginosa. The type of activity displayed depended on the type of strain and sample of essential oil. It is noted that the sensitivity of the experimental strains to the components of the essential oils of P. sibirica and A. sibirica decreases during the transition from the first to the last fraction. We assume that, apparently, this is due to a decrease in the number of monoterpenes in the composition of oils.To study the antiradical activity, the reaction of essential oil components with a stable free 2,2-diphenyl-1-picrylhydrazyl radical was used. Antiradical activity of both whole essential oils of P. sibirica and A. sibirica and their separate fractions was established. There was an increase in antiradical activity with a decrease in the content of monoterpenes in the composition of essential oil. © 2020 Altai State University. All rights reserved.

Аннотация: Essential oil from the spruce branches of Siberian pine (Pinus sibirica Du Tour) and Siberian fir (Abies sibirica Ledeb.) growing on the territory of Krasnoyarsk krai has been obtained by exhaustive hydrosteam distillation. Five separate oil fractions have been extracted: the first was collected 45 min after the onset of distillation; the second, at 2 h; the third, at 5 h; the fourth, at 6 h after the onset of distillation, and the fifth fraction was collected after the termination of hydro-steam distillation. The antimicrobial activity of separate fractions of essential oil from P sibirica and A. sibirica toward the strains of conditionally pathogenic bacteria has been tested: Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus 209p, Micrococcus luteus, Acinetobacter baumanii, and Candida albicans. The results of the study have shown that all samples of essential oils exhibit either bactericidal or bacteriostatic activity toward microbial strains used in the experiment except for Pseudomonas aeruginosa. The type of activity depends on the microbial strain and the sample of essential oil. It has been noted that the sensitivity of the strains to the components of P sibirica and A. sibirica essential oils diminishes on going from the first to the last fraction. It has been assumed that this is due to a decrease in the content of monoterpenes in the oil composition. The antiradical activity has been examined by the reaction of essential oil components with the stable free 2,2-diphenyl-1-picrylhydrazyl radical. It has been found that both whole essential oils from P sibirica and A. sibirica and their individual fractions exhibit antiradical activity. It has been noted that the antiradical activity increases with decreasing content of monoterpenes in the composition of the essential oil.

Аннотация: The growth of bacteria and fungi on a nanofiltration (NF) membrane is known to reduce its permeability and lifetime and increase overall energy use. Over the last decade, application of silver nanoparticles (AgNPs) has shown to present a strong potential in preventing biofouling of NF membrane processes. The paper deals with a novel facile method developed to in situ incorporate nanosilver stabilized with the polyhexamethylene biguanide hydrochloride (PHMB) onto the commercial NF membrane surface. The scanning electron microscopy (SEM) investigations confirmed a uniform distribution of AgNPs on the surface of NF membrane although AgNPs tend to agglomerate into nano-sized colloidal clusters. Our results showed that AgNPs had little impact on the performance of the NF membrane, including salt rejection and water permeation properties. To evaluate the antibacterial properties of nanocomposite membranes, a "time-kill" analysis, a microbiological technique for measuring the change in a population of microorganisms under the impact of a specific sample, has been used against representatives of Gram-positive and Gram-negative bacteria. Inductively coupled mass spectrometry (ICP-MS) was used to study kinetics of Ag release from modified NF membrane. Leaching rates of Ag were low that will possibly result in long-established antimicrobial and antifungal properties. The present research offers a potential for its further use as a new type of modified NF membrane mitigating biofouling.
