A closed ecological system as a means of providing high quality of life in an antarctic station and as a model of a life-support system for the martian mission / J. I. Gitelson [et al.] // International Astronautical Federation - 55th International Astronautical Congress 2004. - 2004. - Vol. 3: International Astronautical Federation - 55th International Astronautical Congress 2004 (4 October 2004 through 8 October 2004, Vancouver) Conference code: 69653. - P1428-1435

Аннотация: This closing technology developed for experimental BIOS-3 facility seems to be highly expedient for providing normal life conditions in high-latitude settlements and first of all for life-support of Antarctic stations. Obvious advantages of ecological life-support system based on photosynthesis, in comparison with used now in Antarctic Continent, are: 1) highly effective cascade usage of energy for performance of all functions of life-support; 2) minimization of environmental pollution due to processing human excretions and polluted water; 3) providing crew with fresh vegetable food all-the-year-round; 4) contact with alive plants is powerful source of positive emotions and effective means of psychological relaxation; 5) significant reduction of the transport charges on delivery of foodstuff to Antarctic Continent. First of all, the usage of closed ecosystem can be recommended for high-mountainous station "Concordia". Similar ecosystems can be used in northern high-latitude settlements - Russian North, Canadian Northern territories, Alaska. Finally, the experience of closed ecological life-support system operation in Antarctic Continent can serve as the best range for modeling some aspects of Martian mission - its ecological, biotechnological and psychophysiological problems - since there are no natural conditions on the Earth closer to Mars with respect to severity of a place.

Bioluminescence -- Database -- Natural and transgenic luminous microorganisms -- Bacteria (microorganisms)
Аннотация: The database BiolumBase was designed for the collection and systematization of available information on microorganisms containing bioluminescent systems; it includes two sections: natural and transgenic luminous microorganisms. By now, logic schemes of these sections have been developed, classification of the objects has been performed, ways of presentation of characteristics and structure of fields for input of information have been elaborated, and the necessary program modules have been developed. The database is filled on the basis of published data and our own experimental results; subsequent linkage of the database to the Internet is envisaged. Users will be able to obtain not only catalogues of strains but also information concerning the properties and functions of the known species of luminous bacteria, the structure, regulatory mechanisms, and application of bioluminescent systems and genetically engineered constructions with lux genes, as well as to find references and to search strains by using any set of attributes. The database will provide information that is of interest for the development of microbial ecology and biotechnology, in particular, for the prediction of biological hazard from the application of transgenic strains.

Аннотация: The present study addresses the seasonal dynamics of productivity and species composition of the meadow and steppe vegetation communities in Khakassia, determined using the ground-based and satellite data of 2017. The MODIS/Terra satellite data were used to analyze the Normalized Difference Vegetation Index (NDVI) and the Land Surface Water Index (LSWI). The NDVI and LSWI were found to be related to the productivity of the meadow and steppe vegetation. The NDVI increased as the portion of the mesophyte grasses in the grass canopy became larger. The LSWI was higher in the steppe communities, which had lower projective coverage, with spots of bare soil, than in the meadow communities, with their abundant vegetation. © Published under licence by IOP Publishing Ltd.

Аннотация: This study investigates synthesis of poly(3-hydroxybutyrate)/diethylene glycol copolymers (P3HB/DEG) by Cupriavidus eutrophus B-10646 cells as related to DEG concentration in the medium and the time when it is added to the culture of cells synthesizing P3HB. The study determines the limits of physiological effect of DEG on C. eutrophus cells, showing that at DEG concentrations above 30 g/L, it inhibits cell growth, decreasing cell concentration and total P3HB/DEG yield and inducing an increase in the degree of saturation of fatty acids in lipids of cell cytoplasmic membrane. A series of copolymers containing different molar fractions of DEG (between 0.13 and 3.0 mol%) have been synthesized and their physicochemical, physical/mechanical, and biological properties have been investigated as related to the chemical composition and proportions of DEG monomers of the polymers. © 2016 American Institute of Chemical Engineers Biotechnol.

Аннотация: The wide use of pesticides in agriculture has caused uncontrolled distribution of these chemicals in the environment, calling for the development and investigation of new environmentally friendly formulations, which would reduce human impact on nature. In the present study, the metribuzin (MET), tribenuron-methyl (TBM), and fenoxaprop-P-ethyl (FPE) herbicides were encapsulated in microparticles of degradable microbial polymers – polyhydroxyalkanoates (PHAs) – of two types – poly-3-hydroxybutyrate [P(3HB)] and poly(3-hydroxybutyrate-co-3-hydroxyvalerate [P(3HB/3HV)]. The use of P(3HB) resulted in higher yields of microparticles (63% to 79%) and larger sizes of the particles, whose average diameter was 0.60 ± 0.06–0.75 ± 0.11 ?m, while the average diameter of copolymer particles varied between 0.43 ± 0.12 and 0.55 ± 0.05 ?m. Encapsulation efficiency was rather determined by the type of herbicide and its solubility, varying from 24.7% to 48.2%. In vitro herbicide release from microparticles to water was affected by herbicide solubility and PHA chemical composition. The readily soluble MET showed the highest release rate, and over 30 days, 64% and 78% of the encapsulated amounts were released from P(3HB) and P(3HB/3HV) microparticles, respectively. High herbicidal activity of microparticles loaded with metribuzin and tribenuron-methyl was demonstrated in the laboratory stands of the Elsholtzia ciliata weed plant. © 2021 Wiley Periodicals LLC.

Аннотация: The proposed elementary mathematical model of formation and decomposition of soil organic matter (SOM) is based on using equations of chemical kinetics to describe the multistage process of SOM transformation. The model both describes each step of transformation in accordance with the law of mass action and postulates the trend of increasing stability of the matter towards further transformation, which is common for all steps. Analysis of the model demonstrates that it is extremely difficult to construct a realistic model of SOM dynamics by assembling elementary models of the type presented in this study into the full description of SOM transformation processes. © 2018 Elsevier B.V.

Аннотация: A series of 3D implants and filling materials prepared from powdered biodegradable polymers, polyhydroxyalkanoates (PHAs), have been designed for the purposes of reparative osteogenesis. The 3D implants are made of resorbable polymer of hydroxybutyric acid (poly-3-hydroxybutyrate, P3HB) and a composite of this polymer with hydroxyapatite (HA) (P3HB/HA). The properties of the implants were studied in vivo in a model of segmental osteotomy and compared with commercial material Bio-Oss®. All implants containing P3HB as the main component facilitate reconstructive osteogenesis. P3HB and P3HB/HA show pronounced osteoplastic properties; their in vivo degradation is slow and corresponds to the growth of a new bone tissue, facilitating normal reparative osteogenesis. Also, powdered P3HB and P3HB/tienam can be used as filling materials for osteoplasty of bone cavities infected by Staphylococcus aureus. Biodegradable 3D implants and P3HB-based filling materials show pronounced osteoplastic properties and degrade in vivo at a slow rate, enabling normal reparative osteogenesis.

Аннотация: In this study, tebuconazole (TEB)-loaded poly-3-hydroxybutyrate (P3HB)-based microparticles were developed and comprehensively characterized. TEB-loaded microparticles with the initial loading amounts of the fungicide of 10, 25, and 50% of the polymer mass (TEB 10, TEB 25, and TEB 50%) were prepared using emulsion technique. Encapsulation efficiency of TEB varied from 59 to 86%. As the loading amount was increased, the average diameter of microparticles increased too, from 41.3 to 71.7 µm, while zeta potential was not influenced by TEB loading, varying between –32.6 and –35.7 mV. TEB was gradually released from the microparticles to the model medium, and after 60 d, from 25 to 43% of TEB was released depending on the content of the encapsulated fungicide. The data obtained from in vitro TEB release were fitted to different mathematical models. It was shown that the release profiles of TEB could be best explained by the Zero-order, Higuchi, and Hixson–Crowell models. The antifungal activity of the P3HB/TEB microparticles against phytopathogenic fungi Fusarium moniliforme and Fusarium solani was demonstrated by in vitro tests conducted in Petri dishes. Thus, hydrophobic agrochemicals (TEB) can be effectively encapsulated into P3HB microparticles to construct slow-release formulations. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.

Аннотация: Nowadays luciferases are effectively used as analytical instruments in a great variety of research fields. Of special interest are the studies dealing with elaboration of novel analytical systems for the purposes of medical diagnostics. The ever-expanding spectrum of clinically important analytes accounts for the increasing demand for new techniques for their detection. In this chapter we have made an attempt to summarize the results on applications of luciferases as reporters in binding assays including immunoassay, nucleic acid hybridization assay, and so on. The data over the last 15 years have been analyzed and clearly show that luciferase-based assays, due to extremely high sensitivity, low cost, and the lack of need for skilled personnel, hold much promise for clinical diagnostics.

Аннотация: This review examines the general principles of bioluminescent enzymatic toxicity bioassays and describes the applications of these methods and the implementation in commercial biosensors. Bioluminescent enzyme system technology (BEST) has been proposed in the bacterial coupled enzyme system, wherein NADH: FMN-oxidoreductase-luciferase substitutes for living organisms. BEST was introduced to facilitate and accelerate the development of cost-competitive enzymatic systems for use in biosensors for medical, environmental, and industrial applications. For widespread use of BEST, the multicomponent reagent "Enzymolum'' has been developed, which contains the bacterial luciferase, NADH: FMN-oxidoreductase, and their substrates, co-immobilized in starch or gelatin gel. Enzymolum is the central part of Portable Laboratory for Toxicity Detection (PLTD), which consists of a biodetector module, a sampling module, a sample preparation module, and a reagent module. PLTD instantly signals chemical-biological hazards and allows us to detect a wide range of toxic substances. Enzymolum can be integrated as a biological module into the portable biodetector-biosensor originally constructed for personal use. Based on the example of Enzymolum and the algorithm for creating new enzyme biotests with tailored characteristics, a new approach was demonstrated in biotechnological design and construction. The examples of biotechnological design of various bioluminescent methods for ecological monitoring were provided. Possible applications of enzyme bioassays are seen in the examples for medical diagnostics, assessment of the effect of physical load on sportsmen, analysis of food additives, and in practical courses for higher educational institutions and schools. The advantages of enzymatic assays are their rapidity (the period of time required does not exceed 3-5 min), high sensitivity, simplicity and safety of procedure, and possibility of automation of ecological monitoring; the required luminometer is easily available.

Аннотация: It has been found that the carbon monoxide (CO)-resistant strain of the hydrogen bacteria Ralstonia eutropha B5786 is able to synthesise polyhydroxy-alkanoates (PHAs) in the presence of CO under autotrophic conditions. This strain, grown on model gas mixtures containing 5-25% CO (v/v), accumulates up to 70-75% (of absolutely dry matter) PHA, without significant variation in the yield coefficient on hydrogen. No suppression of the activities of the key enzymes of PHA synthesis (?-ketothiolase, acetoacetyl-CoA-reductase, butyrate dehydrogenase and poly-3-hydroxybutyrate synthase) was recorded. The PHA synthesised is a copolymer containing mostly ?-hydroxybutyrate (more than 99 mol%) with trace amounts of ?-hydroxyvalerate. The investigated properties of the polymer (molecular weight, crystallinity, temperature characteristics) do not differ from those of the polymer synthesised on electrolytic hydrogen.

Аннотация: It has been found that the carbon monoxide (CO)-resistant strain of the hydrogen bacteria Ralstonia eutropha B5786 is able to synthesise polyhydroxyalkanoates (PHAs) in the presence of CO under autotrophic conditions. This strain, grown on model gas mixtures containing 5-25% CO v/v), accumulates up to 70-75% (of absolutely dry matter) PHA, without significant variation in the yield coefficient on hydrogen. No suppression of the activities of the key enzymes of PHA synthesis (beta-ketothiolase, acetoacetyl-CoA-reductase, butyrate dehydrogenase and poly-3-hydroxybutyrate synthase) was recorded. The PHA synthesised is a copolymer containing mostly beta-hydroxybutyrate (more than 99 mol%) with trace amounts of beta-hydroxyvalerate. The investigated properties of the polymer (molecular weight, crystallinity, temperature characteristics) do not differ from those of the polymer synthesised on electrolytic hydrogen.

Аннотация: The paper presents a brief overview of the results of the implementation of the project "Agropreparations of the new generation: a strategy of construction and realization". The first part contains the analysis of the growth of the wild-type strain Cupriavidus necator B-10646 (formerly eutrophus) and the synthesis of polyhydroxyalkanoates by this strain on various substrates: glycerol, palm oil, Siberian oil seed, sunflower seed oils, and oleic acid. On refined glycerin, a highly productive process is implemented when scaling up, allowing to obtain 128 ± 11 g / L PHA. Evaluation of oils has shown that palm oil is the best carbon substrate. The second part presents the results of the development of environmentally friendly slow-release pesticide formulations. They are a degradable matrix of poly-3-hydroxybutyrate mixed with natural materials (peat, clay, wood flour), into which a pesticide (metribuzin, tribenuron-methyl, fenoxaprop-P-ethyl, azoxystrobin, epoxiconazole, and tebuconazole) has been. The developed preparations showed high activity against pathogenic fungi and weeds and had a much weaker negative effect on the soil microflora. Studies of the degradation of the developed preparations and the release of pesticides into the soil confirm their effectiveness over a long period of time, up to 90 days. © Published under licence by IOP Publishing Ltd.

Аннотация: The Institute of Biophysics SB RAS hosts and maintains a specialized collection of luminous bacteria (CCIBSO 836) containing over 700 strains isolated in various regions of the world's oceans. The culture collection is a source of lux genes and biologically active substances. The wide application of bioluminescence in medicine and ecology has given importance to analys-ing information on the structure and functioning of bioluminescence systems in natural and transgenic microorganisms, as well as on their features that are closely interrelated with bioluminescence. The aims of our BIOLUMBASE database are: gathering information on microorganisms with lux genes, their analysis and free access, and distribution of this data throughout the global network. The database includes two sections, natural and transgenic luminous microorganisms, and is updated by our own experimental results, the published literature and internet resources. For the future, a publicly available internet site for BIOLUMBASE is planned. This will list the strains and provide comprehensive information on the properties and functions of luminous bacteria, the mechanisms of regulation of bioluminescence systems, constructs with lux genes, and applications of bioluminescence in microbiology, ecology, medicine and biotechnology. It is noteworthy that this database will also be useful for evaluation of biological hazards of transgenic strains. Users will be able to carry out bibliographic and strain searches starting from any feature of interest. Copyright В© 2005 John Wiley & Sons, Ltd.

Bioluminescent properties of semi-synthetic obelin and aequorin activated by coelenterazine analogues with modifications of C-2, C-6, and C-8 substituents / E. V. Eremeeva, T. Jiang, N. P. Malikova [et al.] // Int. J. Mol. Sci. - 2020. - Vol. 21, Is. 15. - Ст. 5446. - P1-21, DOI 10.3390/ijms21155446 . - ISSN 1661-6596

Аннотация: Ca2+-regulated photoproteins responsible for bioluminescence of a variety of marine organisms are single-chain globular proteins within the inner cavity of which the oxygenated coelenterazine, 2-hydroperoxycoelenterazine, is tightly bound. Alongside with native coelenterazine, photoproteins can also use its synthetic analogues as substrates to produce flash-type bioluminescence. However, information on the effect of modifications of various groups of coelenterazine and amino acid environment of the protein active site on the bioluminescent properties of the corresponding semi-synthetic photoproteins is fragmentary and often controversial. In this paper, we investigated the specific bioluminescence activity, light emission spectra, stopped-flow kinetics and sensitivity to calcium of the semi-synthetic aequorins and obelins activated by novel coelenterazine analogues and the recently reported coelenterazine derivatives. Several semi-synthetic photoproteins activated by the studied coelenterazine analogues displayed sufficient bioluminescence activities accompanied by various changes in the spectral and kinetic properties as well as in calcium sensitivity. The poor activity of certain semi-synthetic photoproteins might be attributed to instability of some coelenterazine analogues in solution and low efficiency of 2-hydroperoxy adduct formation. In most cases, semi-synthetic obelins and aequorins displayed different properties upon being activated by the same coelenterazine analogue. The results indicated that the OH-group at the C-6 phenyl ring of coelenterazine is important for the photoprotein bioluminescence and that the hydrogen-bond network around the substituent in position 6 of the imidazopyrazinone core could be the reason of different bioluminescence activities of aequorin and obelin with certain coelenterazine analogues. © 2020 by the authors.

Аннотация: This work is a review of the results of biomedical studies of polymer devices (films, fibers, microparticles, 30 implants) made from resorbable PHAs synthesized by the bacterium Wautersia (Ralstonia) eutropha 65786, using the technology developed at the Institute of Biophysics of the Siberian Branch of the Russian Academy of Sciences. Two types of PHAs - polyhydroxybutyrate (PHB) and a hydroxybutyrate/hydroxyvalerate copolymer (PHB/PHV) - have been proven to be biocompatible in vitro in cultures of fibroblasts, endothelial cells, hepatocytes, and osteoblasts, and in short- and long-duration experiments on animals. Polymer films and membranes have been found to be usable as scaffolds for functioning cells and monofilament suture fibers - for stitching muscular-fascial wounds and in abdominal surgery. Ectopic bone formation assay and experiments with the model of segmental osteotomy showed that 30 PHB and PHB/HA implants can be used for reparative osteogenesis. The paper reports beneficial results of using polymers to repair bone defects in oral surgery. Copyright В© 2008 WILEY-VCH Verlag GmbH & Co. KGaA.

Аннотация: This report presents some new methodological opportunities that biophysics can offer for solving the fundamental problem of planetary ecology-deciphering the mechanism that maintains the equilibrium state of the biosphere. The Institute of Biophysics, Siberian Branch, Russian Academy of Sciences, where the author of this report works, is developing two complementary directions in ecological biophysics. The first is monitoring the vital activity of natural and constructed ecosystems by optical methods using the example of bioluminescence of the sea and closed ecosystems, and the second is studying the laws of parametric biosynthesis control and creating biotechnological control systems for these processes in order to construct noosphere-like ecosystems, in particular, for human life-support and survival systems in extreme conditions on the Earth and in space.
