Аннотация: One of the ways of solving the problem of the human liquid wastes utilization in bioregenerative life support systems (BLSS) can be the use of halophytic vegetable plant Salicornia europaea capable of accumulating sodium chloride in rather high concentrations. Since the most specific higher plant function in BLSS, which at present cannot be substituted by physicochemical processes, appears to be the biosynthesis of a wide spectrum of nutritive substances necessary for a human, the object of the given work was the investigation of the S. europaea productivity, biochemical and mineral composition when grown under close to optimal BLSS vegetative component conditions. As the use of human urine after its preliminary physicochemical processing is supposed to be the mineral solution basis for the S. europaea cultivation, it is necessary to clear up the effect of reduced nitrogen on plants growth. Ground research was carried out. Biochemical composition of the S. europaea edible part showed that crude protein was contained in the highest degree. At that the content of crude protein (24% per dry weight) and cellulose (4.7% per dry weight) was higher in the plants grown on solutions containing amide nitrogen in comparison with the plants grown on solutions with nitrate nitrogen (15.4%-3.1% correspondingly). The water-soluble sugar contents were not high in the S. europaea edible part and depending on the nitrogen nutrition form they amounted to 1.1% (amide nitrogen) and 1.5% (nitrate nitrogen). The polysaccharide number (except cellulose) was rather higher and varied from 7.7% to 8.2%. Although the lipid content in the S. europaea plants was relatively low (7% per dry weight), it was shown that the plant lipids are characterized by a high nonsaturation degree mainly due to alpha linolenic and linoleic acids. Nitrogen nutrition form did not significantly affect the S. europaea productivity, and dry edible biomass of one plant was 8.6 g. Sodium and its concentrations predominated in the plant mineral composition and amounted in average to 9% per dry weight. Thus the S. europaea being the vegetable plant it can be the source of several biochemical substances and essential fatty acids. The present work also considers the influence of nitrate and amide forms of nitrogen on S. europaea biochemical and mineral composition. В© 2008 Elsevier Ltd. All rights reserved.

Effects of mineral nutrition conditions on heat tolerance of chufa (Cyperus esculentus L.) plant communities to super optimal air temperatures in the BTLSS / E. S. Shklavtsova [et al.] // Adv. Space Res. - 2014. - Vol. 54, Is. 6. - P1135-1145, DOI 10.1016/j.asr.2014.05.031 . - ISSN 1879-1948

Аннотация: The use of mineralized human wastes as a basis for nutrient solutions will increase the degree of material closure of bio-technical human life support systems. As stress tolerance of plants is determined, among other factors, by the conditions under which they have been grown before exposure to a stressor, the purpose of the study is to investigate the level of tolerance of chufa (Cyperus esculentus L.) plant communities grown in solutions based on mineralized human wastes to a damaging air temperature, 45 °C. Experiments were performed with 30-day-old chufa plant communities grown hydroponically, on expanded clay aggregate, under artificial light, at 690 ?mol m-2 s-1 PAR and at a temperature of 25 °C. Plants were grown in Knop's solution and solutions based on human wastes mineralized according to Yu.A. Kudenko's method, which contained nitrogen either as ammonium and urea or as nitrates. The heat shock treatment lasted 20 h at 690 and 1150 ?mol m -2 s-1 PAR. Chufa heat tolerance was evaluated based on parameters of CO2 gas exchange, the state of its photosynthetic apparatus (PSA), and intensity of peroxidation of leaf lipids. Chufa plants grown in the solutions based on mineralized human wastes that contained ammonium and urea had lower heat tolerance than plants grown in standard mineral solutions. Heat tolerance of the plants grown in the solutions based on mineralized human wastes that mainly contained nitrate nitrogen was insignificantly different from the heat tolerance of the plants grown in standard mineral solutions. A PAR intensity increase from 690 ?mol m -2 s-1 to 1150 ?mol m-2 s-1 enhanced heat tolerance of chufa plant communities, irrespective of the conditions of mineral nutrition under which they had been grown. © 2014 COSPAR.

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.
