Air disinfection from bacteria and viruses by means of photocatalytic oxidation is investigated with microorganisms loaded over photocatalysts' films aerosols. Deposition method equipment have been developed to load Mycobacterium smegmatis, Bacillus thuringiensis, vaccinia virus, influenza A (H3N2) virus on slides undoped TiO2 platinized sulfated (Pt/TiO2). Inactivation dynamics was measured under UVA irradiation in the dark. About 90% inactivation reached 30 min 90 99.8% Pt/TiO2. The...
Atmospheric sounding using the Tu-134 Optik aircraft-laboratory was conducted in September 2020 over seas of Russian sector Arctic Ocean, namely Barents, Kara, Laptev, East Siberian, Chukchi and Bering seas. Unique samples atmospheric aerosols at altitudes from 200 up to 10,000 m were taken, including for identification cultivated microorganisms their genetic analysis. Data on concentration diversity bacteria fungi isolated 24 are presented; main phenotypic genomic characteristics obtained...
Background: Biological components of atmospheric aerosol affect the quality air. Long-term trends in changes concentrations total protein (a universal marker biogenic component aerosol) and culturable microorganisms air are studied. Methods: Atmospheric samples taken at two locations south Western Siberia during airborne sounding atmosphere. Sample analysis is carried out laboratory using standard culture methods (culturable microorganisms) fluorescence method (total protein). Results:...
This research investigates a promising antiviral compound based on polyprenols from Siberian silver fir (Abies sibirica). The physico-chemical characteristics of preparation developed in aerosol form and an estimation its protective efficacy against challenge laboratory animals are presented. It is shown that (1) by using simple ultrasonic disperser one can obtain three formulations studied with about 70% mass accumulated the size range below 1.8 microm; (2) 40-100% particles contain for...
Abstract Multi‐year monitoring of atmospheric bioaerosol in Southwestern Siberia revealed the presence a large number various culturable microorganisms. It is known that viable microorganisms can cause directly or provoke different human diseases. It's very difficult to evaluate danger represented by each microorganism man directly. Therefore, relatively simple method required for evaluation potential whole assembly an aerosol sample. For bacteria, be based on individual characteristics...
The purpose of this study was to compare the concentration total protein, as well composition and abundance culturable microorganisms in atmospheric aerosols collected over Vasyugan marshes Karakan pine forest during a flight September 2018 at altitudes from 500 7000 m. determined concentrations protein samples were on average much less than those for same area other years. aerosol by cultural methods isolate genotyping. Altitude dependences revealed. A rather stable altitude profile...
This study demonstrates the possibility of achieving a prophylactic effect by intramuscular injection Abies sibirica polyprenols for control influenza virus infection in mice. One five polyprenol preparations tested, preparation N1, which had lowest hydrophilic-lipophilic balance (8.6), produced significant protective when injected dose 2000 μg/mouse 2 days before aerosol mice with virus. A moderate was also observed using second preparation, designated N2. day after infection, animals...
To contribute to the comprehensive study of atmospheric pollution in Siberia, aircraft soundingwas carried out Northwestern Siberian along following route: Novosibirsk - Surgut Igarka Novosibirsk. This work was aimed at studying quantity and representation culturable microorganisms other biogenic components atmosphere altitudes up 8,000 m. The air samples were collected impingers (flow rate 50 ± 5 L/min) where ml Hanks’ solution (ICN Biomedicals) used as sorbing liquid applied on fibrous...
One of the most important components atmospheric aerosols are microorganisms. Therefore, it is necessary to assess hazard humans, both from individual microorganisms which present in bioaerosols as well their pool. An approach for determining bacteria and yeasts found humans has previously been proposed. The purpose this paper compare our results 2006–2008 with studies obtained 2012–2016 identify changes characteristics occurring over a decade south Western Siberia. Experimental data on...
Quick label-free virus screening and highly sensitive analytical tools/techniques are becoming extremely important in a pandemic. In this study, we developed biosensing device based on the silicon nanoribbon multichannel dielectrophoretic controlled sensors functionalized with SARS-CoV-2 spike antibodies for use as platform detection studding of properties viruses their protein components. Replicatively defective viral particles vesicular stomatitis HIV-1 were used carrier molecules to...
The atmospheric environment is formed under the influence of local and distant sources as a result horizontal vertical transport. In present work, microbiological analysis 604 samples aerosol collected in period from September 2020 to 2023 at four sites differing anthropogenic load, located Novosibirsk region, was carried out. Day night were during 12 h every two weeks by filtration using Sartorius reinforced Teflon membranes, then sown on set nutrient media. taxonomic affiliation isolated...
It was noted that the detection time of West Nile virus protein E by standard methods – immunoenzyme assay for antigen, antibody seroconversion, polymerase chain reaction with reverse transcription, isolation and neutralization assay, is at least one hour. (genus Flavivirus) belongs to Japanese encephalitis antigenic complex family Flaviviridae capable causing fever or severe disease. To increase rate recombinant virus, an express method using developed promising biosensor-based analytical...
