Заглавие : Possibility of Salicornia europaea use for the human liquid wastes inclusion into BLSS intrasystem mass exchange

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.

Заглавие : Biochemical fractionation and cellular distribution of americium and plutonium in the biomass of freshwater macrophytes

Аннотация: Accumulation of americium ( 241Am) and plutonium ( 238,242Pu) and their distribution in cell compartments and biochemical components of the biomass of freshwater aquatic plants Elodea canadensis, Ceratophyllum demersum and Myrioplyllum spicatum and aquatic moss Fontinalis antipyretica have been investigated in laboratory experiments. Americium and plutonium taken up from water by Elodea canadensis apical shoots were mainly absorbed by structural components of plant cells (90% for 241Am; 89% for 238Pu and 82-87% for 242Pu). About 10-18% of isotope activity was recorded in the cytosol fraction. The major concentration (76-92%) of americium was bound to cell wall cellulose-like polysaccharides of Elodea canadensis, Myriophyllum spicatum, Ceratophyllum demersum and Fontinalis antipyretica, 8-24% of americium activity was registered in the fraction of proteins and carbohydrates, and just a minor concentration (<1%) in the lipid fraction. The distribution of plutonium in the biomass fractions of Elodea was similar to that of americium. Hence, americium and plutonium had the highest affinity to cellulose-like polysaccharides of cell walls of freshwater submerged macrophytes. В© 2011 Akademiai Kiado, Budapest, Hungary.

Ключевые слова (''Своб.индексиров.''): biopolymer--gelatin--starch--physical gel--microviscosity--molecular--rotor
Аннотация: The problem of correlation between rheological properties in macro- and micro- scales of media with biopolymers of polypeptide (gelatin) and polysaccharide (starch) nature is investigated. The viscosity of the biopolymer solutions with concentrations 0.5-5 wt% was estimated by standard rotational rheometry technique and with fluorescent molecular rotor at 15-50 A degrees C. Opposite trends were observed for relationship between microviscosity eta (m) and macroviscosity eta for two biopolymers: eta (m) eta for gelatin and eta (m) eta for starch solutions. The temperature dependence of eta (m) followed the monoexponential decay law in all samples over the whole temperature range indicating insensitivity of microviscosity to gel mesh melting under heating. The dissimilarity of macro- and micro-rheological properties of gelatin and starch-containing media is discussed in terms of difference in architecture of the gels.

Заглавие : Estimating levels of light emission and extracellular peroxidase activity of mycelium of luminous fungus Neonothopanus nambi treated with ?-glucosidase
Место публикации : Curr. Res. Environ. Appl. Mycol. J. Fungal: Beijing Academy of Agriculture and Forestry Sciences, Institute of Plant and Environment Protection, 2018. - Vol. 8, Is. 1. - С. 75-85. - ISSN 22292225 (ISSN) , DOI 10.5943/cream/8/1/6
Ключевые слова (''Своб.индексиров.''): basidiomycetes--cell wall--luminescence--polysaccharide sheath
Аннотация: The present study estimates the level of extracellular peroxidase activity and light emission intensity of mycelium of luminescent basidiomycete Neonothopanus nambi treated with ?-glucosidase. A hypothesis has been proposed that treatment with ?-glucosidase may trigger biochemical mechanisms of activation of ROS (primarily hydrogen peroxide) generation in N. nambi mycelium. The results obtained indicate that the enzyme causes partial disintegration of the slimy sheath of fungal hyphae and intracellular matrix, which leads to release of the extracellular peroxidases to the incubation medium. Mycelial cells treated with the enzyme reach the peak of their luminescence sooner. It has been assumed that partial loss of extracellular peroxidases, as important enzymes of antioxidant defense, may be compensated for by an increase in the level of light emission by the fungus. © 2018 Beijing Academy of Agriculture and Forestry Sciences.

Аннотация: In this work, magnetite nanoparticles coated with polysaccharides were synthesized. Arabinogalactan and chitosan were used as polysaccharides. The possibilities of immobilization of biospecific molecules on the surface of the obtained composites were studied. Experiments on covalent immobilization of biospecific molecules on magnetic nanoparticles coated with a polysaccharide showed a high density of immobilized molecules. This suggests the use of such materials in bioanalytical systems or as affinity sorbents. (c) 2020 Elsevier B.V. All rights reserved.
