Аннотация: To create a life support system based on biological and physical-chemical processes is the optimum solution providing full-valued condidtions for existence and efficient work of people at a lunar base. Long-standing experinece in experimental research or closed ecosystems and their components allows us to suggest a realistic functional structure of the lunar base and to estimate qualitatively its parameters. The original restrictions are as follows: 1) the basic source of energy to support the biological processes has to be the solar radiation; 2) the initial amount of basic biological elelments forming the turnover of substances (C, O, H, P, K, N) has to be delivered from Earth; 3). Moon materials are not to be used in the biological turnover inside the base; 4) the base is to supply the crew fully with atmosphere and water, and with 90% (A scenario) or 40% (B scenario) of food. Experimental data about the plant productivity under the "Moon" rhythm of light and darkness allow us to suggest that the A scenario requires per one human: plant area - 40 m2 irradiated during the lunar day by 250-300 W/m2 PAR producing 1250 g of dry biomass a terrestrial day; a heterotrophic component of "biological incineration" of inedible plant biomass (800 g/day) including the aquaculture of fish to produce animal products and contaminating the environment less than birds and mammals, and the culture of edible mushrooms; a component of physical-chemical correction for the LSS envi ronment including the subsystems of: deep oxidation of organic impurities in the atmosphere and of water, organic wastes of human activity and that biological components (420 g/day) Co2 concentration in "Moon" nights, damping O2 in "Moon" days, etc. The stock of presotred or delivered from Earth substances (food additions, seeds, etc.) to be involved in biological turnover is to be about 50 kg/year per man. Increase of the mass of prestored substances per man up to 220 kg/year would reduce twice the plant area and consumed amount of radiant energy to exclude the components of "biological incineration" and physical-chemical destruction of organic wastes.

Direct utilization of human liquid wastes by plants in a closed ecosystem / G. M. Lisovsky [et al.] // Advances in Space Research. - 1997. - Vol. 20, Is. 10. - P1801-1804 . - ISSN 0273-1177

Аннотация: Model experiments in phytotrons have shown that urea is able to cover 70% of the demand in nitrogen of the conveyer cultivated wheat. At the same time wheat plants can directly utilize human liquid wastes. In this article by human liquid wastes the authors mean human urine only. In a long-term experiment on "man-higher plants" system with two crewmen, plants covered 63 m2, with wheat planted to - 39.6 m2. For 103 days, complete human urine (total amount - 210.7 1) wassupplied into the nutrient solution for wheat. In a month and a half NaCl supply into the nutrient solution stabilized at 0.9-1.65 g/l. This salination had no marked effect on wheat production. The experiment revealed the realistic feasibility to directly involve liquid wastes into the biological turnover of the life support system. The closure of the system, in terms of water, increased by 15.7% and the supply of nutrients for wheat plants into the system was decreased. Closedness of biological turnover of matter in a man-made "man - higher plants" ecological system might involve, among other processes, direct utilization of human liquid wastes by plants. The amount of urine comprises 15-20% of the total amount of water cycling within the system including water as part of food, household, hygiene and potable water necessary for man. What is more, it they contains most nitrogen-bearing compounds emitted by man, almost all of the NaCl and some other substances involved in the biological turnover. Human liquid wastes can be utilized either by preliminary physical-chemical treatment (evaporating or freezing out the water, finally oxidizing the organic matter, isolating the mineral components required for plants, etc.) and further involvement of the obtained products or by direct application into the nutrient solution for plants. The challenge of direct utilization is that plants have no need of Na+ and Cl-, and also the organic forms of nitrogen emitted by man cannot fully meet the demand of plants forthis element. Besides, hygienic and/or psychological reasons make it desirable to avoid direct use of liquid wastes in the nutrient solutions that would have direct contact with edible part of plants (tubers, roots, bulbs). Feasibility of direct utilization of liquid wastes by plants in a closed "man - higher plants" ecosystem has been experimentally studied on wheat - grain culture as a model plant with the edible part in the form of seeds spatially dissociated with the nutrient medium. The wheat covered 60-65% of the area under higher plants. The studies have been carried out in "Bios-3"experimental facility described in detail elsewhere (Lisovsky, 1979; Gitelson et al., 1989).

Аннотация: The life support systems (LSS) for long-term missions are to use cycling-recycling systems, including biological recycling. Higher plants are the traditional regenerator of air and producer of food. They should be used in many successive generations of their reproduction in LSS. Studies of influence of microbial associations on germination of wheat seeds and on growth of seedlings under impact of heavy metals are necessary because of migration of heavy metals in LSS. Microbial associations are able to stimulate growth of plants, to protect them from pathogenic organisms and from toxicity of heavy metal salts. The goal of this work was to investigate effect of microbial associations on the germination of wheat seeds and on the growth of seedlings under impact of different concentrations of ZnSO4. The results of investigations showed that:(1)Zinc salt had an adverse effect on germination of wheat seeds, beginning with concentrations of 8 MPC (Maximum Permissible Concentration) and higher.(2)Microbial associations (concentrations -104 to 107 cells/ml) were able to decrease (partly or completely) the adverse effect of ZnSO4 on germination of wheat seeds.(3)Concentrations (104-107 cells/ml) of microbial associations were able to decrease partly the adverse effect of zinc salts (intervals: from 1 to 32 MPS{cyrillic}) on the growth and development of wheat plantlets during heterotrophic phase.(4)The root system of plants was more sensitive to the adverse effect of ZnSO4 than shoots of plants.

Аннотация: A mathematical model describing the interaction of plants and rhizospheric microorganisms on complete mineral medium at a higher CO2 level in the atmosphere was constructed. The positive effect of CO2-enrichment on the system plant--rhizospheric microorganisms was shown. The effect of rhizospheric microorganisms on plant growth at normal and high level of carbon dioxide was demonstrated. It was shown that the biomass of plant in the system is smaller than the biomass of plant growing without microorganisms. It was experimentally demonstrated that a simple ecosystem wheat--Pseudomonas putida--artificial soil develops and functions differently than its individual constituents in the case of a wheat-artificial soil system. With unlimited nutrition and a higher CO2 level (0.06%), plants with roots inoculated with microorganisms have a smaller biomass than plants that were not inoculated with microorganisms.

Аннотация: The influence of two rhizosphere bacteria-Pseudomonas fluorescens and Pseudomonas putidaon the growth of wheat seedlings was studied under conditions of complete mineral supply and nitrogen deficiency in the medium. On complete mineral medium, the plants that developed from the seeds inoculated with the pseudomonads had some advantages for growth over those developed from the non-inoculated seeds. Inoculated plants showed an increased transpiration and a higher content of organic nitrogen in their biomass. Under conditions of nitrogen deficiency in the medium, no differences were found between inoculated and noninoculated plants. No competition for the nitrogen sources was revealed between the bacteria and plants; the development of the rhizosphere bacteria was limited by the rate of organic compound excretion by plant roots. The stimulatory effect produced on plant growth by the rhizosphere bacteria was shown to vary depending on the environmental factors.

Аннотация: The effect has been studied of inoculation of seeds of wheat with two species of rhizospheric microorganisms, -Pseudomonas fluorescens and Pseudomonas putida - on young plant growth with complete and with nitrogen deficit mineral nutrition. With complete mineral medium, plants grown from seeds inoculated with bacteria of Pseudomonas genus (experiment plants) have been found to have better growth over plants not inoculated with these bacteria (control plants). The experiment plants had increased transpiration and their biomass had higher organic nitrogen content. With nitrogen deficit medium, the plants inoculated with bacteria and those without them, have not revealed changes in growth. Neither case demonstrated competition of microorganisms with plants for nitrogen sources. В© 1997 COSPAR. Published by Elsevier Science Ltd.

Аннотация: Response of "wheat plants--rhizospheric microorganisms--artificial soil"--a simple terrestrial ecosystem--to carbon dioxide increased in its atmosphere to 0.06% has been studied. It has been experimentally demonstrated that a simple ecosystem develops and functions different from its individual elements (components), in this case "plants-artificial soil" without microorganisms. With mineral nutrition unlimited and CO2 enrichment the system is capable of binding (involving into turnover) 40% more carbon than the system without microorganisms. With material balance as the basis, this article evaluates the contribution of a system's elements into its development, namely, the contribution of the photosynthesizing component and the contribution of microorganisms.

Аннотация: The biodegradable polymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate) has been used to design experimental sustained-release formulations of the herbicide Zellek Super in the form of films and microgranules. The kinetics of polymer degradation and the dynamics of herbicide release show that the rate and extent of herbicide release from the polymer matrix into the soil depends on the geometry of the carrier and the proportion of the pesticide loaded into it (polymer/pesticide mass ratio). Experiments with the creeping bentgrass (Agrostis stolonifera L.) show that the formulations of the herbicide Zellek Super constructed as microgranules and films can be successfully used to suppress the growth of grasses. This study is the first to demonstrate that biodegradable polyhydroxyalkanoates can be used effectively to construct environmentally friendly sustained-release PHA-herbicide systems that can be placed into the soil together with seeds.

Аннотация: One of the key problems of long-term space missions is limited service life of units. The only exceptions are biological components of biological Life Support Systems - higher plants or microorganisms. These components are capable of self-restoration: after complete disintegration, they can appear again from seeds or spores. The estimate of failure intensity of BLSS regeneration component includes: a number of self-sustained sections of the regeneration component; permissible boost (how many times can productivity of a component be increased); time required to repair (restore) a component; the crew existence time, when all LSS regeneration components fail; failure rate of one section of a regeneration component. Evaluations show that for hydrogen-oxidizing bacteria and micro-algae very high reliability is achieved even for one or two sections. In the case of higher plants (due to low rate of self-restoration) bio-regenerative module has to be divided into 10 self-sustained sections operating simultaneously. These measures can decrease the probability of catastrophe by a factor of 10 (C) 1999 COSPAR. Published by Elsevier Science Ltd.

One of the approaches to preventing these problems is to develop controlled release forms of fertilisers. RESULTS: Experimental formulations of the nitrogen fertiliser urea loaded in a degradable matrix of the natural polymer poly-3-hydroxybutyrate (P3HB) in the form of films, pellets and coated granules were constructed and investigated. Nitrogen release into soil occurred as the polymer was degraded, and it was dependent on the geometry of the carrier and the amount of nitrogen loaded in it, showing that nitrogen release can last for 30 days or longer and that release rates can be controlled by varying the fabrication technique employed. P3HB/urea formulations have a favourable effect on the soil microbial community. The use of embedded urea has a beneficial influence on the growth of creeping bentgrass (Agrostis stolonifera) and lettuce (Latuca sativa) and reduces removal of nitrogen with drain water. CONCLUSION: The slow-release nitrogen formulations developed in this study can be buried in soil together with seeds preventing nitrogen deficiency. The use of such slow-release formulations can decrease the amounts of chemicals in the environment and prevent their adverse effects on the biosphere. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry

Constructing Slow-Release Formulations of Ammonium Nitrate Fertilizer Based on Degradable Poly(3-hydroxybutyrate) / A. N. Boyandin [et al.] // J. Agric. Food Chem. - 2017. - Vol. 65, Is. 32. - P6745-6752, DOI 10.1021/acs.jafc.7b01217 . - ISSN 0021-8561

Аннотация: The present study describes construction and investigation of experimental formulations of ammonium nitrate embedded in a matrix of degradable natural polymer poly-3-hydroxybutyrate [P(3HB)] and P(3HB) blended with wood flour shaped as tablets, some of them coated with P(3HB). Kinetics of ammonium release into soil as dependent on the composition of the polymer matrix was investigated in laboratory experiments. The rates of fertilizer release from formulations coated with a biopolymer layer were considerably (two months or longer) slower than the rates of fertilizer release from uncoated formulations, while release from polymer and composite (polymer/wood flour) formulations occurred with comparable rates. The use of the experimental formulations in laboratory ecosystems with wheat (Triticum aestivum L.) was more effective than application of free ammonium nitrate. The advantage of the slow-release fertilizer formulations is that they are buried in soil together with the seeds, and the fertilizer remains effective over the first three months of plant growth. The use of such slow-release formulations will reduce the amounts of chemicals released into the environment, which will curb their accumulation in food chains of ecosystems and mitigate their adverse effects on the biosphere. © 2017 American Chemical Society.

Аннотация: Fungicidal activity of experimental tebuconazole (TEB) formulations was investigated in laboratory soil ecosystems in wheat plant communities infected by Fusarium moniliforme. TEB was embedded in the matrix of poly-3-hydroxybutyrate, shaped as films and microgranules. These formulations were buried in the soil with wheat plants, and their efficacy was compared with that of commercial formulation Raxil and with the effect of pre-sowing treatment of seeds. In the experiment with the initially infected seeds and a relatively low level of natural soil infection caused by Fusarium fungi, the effects of the experimental P(3HB)/TEB formulations and Raxil were comparable. However, when the level of soil infection was increased by adding F. moniliforme spores, P(3HB)/TEB granules and films reduced the total counts of fungi and the abundance of F. moniliforme more effectively than Raxil. Seed treatment or soil treatment with Raxil solution showed an increase in the percentage of rot-damaged roots in the later stages of the experiment. In the early stage (between days 10 and 20), the percentage of rot-damaged roots in the soil with TEB embedded in the slowly degraded P(3HB) matrix was similar to that in the soil with Raxil. However, the efficacy of P(3HB)/TEB formulations lasted longer, and in later stages (between days 20 and 30), the percentage of rot-damaged roots in that group did not grow. In experiments with different TEB formulations and, hence, different fungicidal activities, the increase in plant biomass was 15-17 to 40-60% higher than in the groups where TEB was applied by using conventional techniques.

Аннотация: The Allium-test is commonly used to assess genotoxicity of chemical and physical factors. In the present study, the roots of germinating onion (Allium cepa) were exposed to 0.02–13 Gy of ?-radiation. The dose dependencies of the frequency of chromosomal aberrations and micronuclei were nonlinear. An increase in the frequency of chromosomal aberrations in germinating seed root cells was first found under exposure to low doses of ?-radiation (0.05 and 0.1 Gy). Micronuclei inductions at low doses of radiation were not significantly different from the control. Our study suggests that germinating onion seed roots are a sensitive bioassay material for assessing the genotoxic effects of low-dose ?-radiation. © 2019 Elsevier Ltd

Аннотация: By the method of exhaustive hydroponically obtained essential oil from beans of Heracleum dissectum Ledeb., growing in the Krasnoyarsk region. Separate fractions of oil were obtained: the first after 45 minutes from the beginning of distillation, the second – after 2 hours, the third-after 5 hours, the fourth fraction was collected after the end of hydro-distillation. The component composition of both whole essential oil and its separate fractions was studied. The main components are octyl acetate (60.0%), octyl-2-methylpropanoate (10.2%), n-hexyl-2-methylbutanoate (9.0%). The main amount of octyl acetate (64.7%) is concentrated in the first fraction of the oil. The antimicrobial activity of various fractions of essential oil of borscht dissected against strains of opportunistic microorganisms: Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus 209p, MRSA, Proteus vulgaris. It was found that, depending on the duration of isolation, the antimicrobial activity of essential oil fractions in relation to Staphylococcus aureus 209p, MRSA and Pseudomonas aeruginosa decreases, and in relation to Escherichia coli, Klebsiella pneumoniae and Proteus vulgaris increases. The most pronounced inhibitory effect of the third and fourth fractions of essential oil against Klebsiella pneumonia. The antiradical activity of all studied samples of borscht essential oil dissected in reaction with stable free 2,2-diphenyl-1-picrylhydrazyl radical was established. The first fraction showed minimal antiradical activity (15.1%), the fourth – maximum (49.2%). © 2020 Altai State University. All rights reserved.

Allium cepa -- onion seedlings -- gamma-radiation -- low dose -- dose dependency
Аннотация: Purpose The purpose of this study was to assess the long-term effects of gamma-radiation, including low-dose radiation, on growth parameters of onion (Allium cepa) seedling roots 6-10 days after irradiation. Materials and methods Onion seedlings were exposed to a Cs-137 gamma source at doses ranging from 0.1 to 10 grays (Gy). Responses of root and shoot length growth were studied 6 and 10 days after irradiation. Results Our results showed inhibition of the root and shoot length growth 6 days after exposure at all doses, including the low dose - 0.1 Gy. At a later point in time (day 10), root and shoot inhibition was only observed after irradiation at high doses (above 5 Gy), and that suggested the occurrence of cell repair after irradiation at low doses. The results indicated that the length of seedling roots was more sensitive to gamma-irradiation than the shoot length. Conclusion The results of the study suggested that short-term gamma-irradiation of onion seedlings (absorbed doses of 0.1-10 Gy) caused inhibition of plant growth 6 and 10 days after irradiation. The dose dependence of the onion root length was linear. The present study showed for the first time that short-term low-dose gamma-irradiation could induce long-term negative effects on plant growth.

Аннотация: The paper dwells upon the use of autochthonous microbial cinosis as a source of antagonistic strains for bioprotection of wheat against Fusarium in biotechnical life support systems (BT LSS). Six bacterial strains antagonistic to 9 phytopathogenic fungi Fusarium responsible for seedling blight of wheat in BT LSS were isolated from hydroponic solutions and artificial soils and subject to the genetic typing. Five strains represent bacteria g. Bacillus, one strain - Chryseobacterium. The 16S rRNA sequencing showed 94 to 100 % genetic affinity with typical cultures. All spore-forming strains-antagonists were capable of germinating and going through the whole development cycle In the presence of swelling wheat seeds. The isolates did not demonstrate antagonism to each other and can grow in a mixed culture. Spectra and levels of the antiobiotic activity of the antagonists, along with the Fusarium sensitivity to their antibiotic action, differed statistically (p < 0.001). None of the antagonists was capable of suppressing the entire Fusarium spectrum detected in BT LSS individually. At the same time, treatment of seeds with a mixture of antagonists suppressed totally fungal development in wheat artificially inoculated by Fusarium conidia from a BT LSS roll culture, and had a statistical stimulating effect (p = 0.01) on seedlings. © 2020 Slovo Ltd.
