Biosorption of 241Am from solution and its biochemical fractionation in the mycelium of macromycetes / D. V. Dementyev [et al.] // Radiochemistry. - 2015. - Vol. 57, Is. 6. - P661-665, DOI 10.1134/S1066362215060144 . - ISSN 1066-3622

Аннотация: Experiments with macromycetes Pleurotus ostreatus, Neonothopanus nambi, and Agaricus bisporus demonstrated for the first time that live mycelium of mushrooms, cultivated on a liquid culture medium, can efficiently take up dissolved 241Am in its biomass. Biochemical fractionation of the mycelium biomass demonstrated for the first time that the major fraction (up to 90%) of 241Am accumulated in the mycelium is bonded to structural polysaccharides of the cell walls. The sorption capacity of cell wall polysaccharides for 241Am is 2.7-3.6 times higher than that of the initial mycelium biomass, and the activity concentration of 241Am in the polysaccharides reached 950 Bq g-1 dry weight. © 2015 Pleiades Publishing, Inc.

Effect of biohumus on growth of oyster fungus Pleurotus ostreatus and Agaricus bisporus [Текст] / N. S. Manukovsky, V. S. Kovalev // Mikol. Fitopatol. - 1998. - Vol. 32, Is. 5. - P. 67-70. - Cited References: 8 . - ISSN 0026-3648

Аннотация: The influence of biohumus on the yeild of oester mushroom has been studied. It was shown, that the highest yeild 9.73 g of dry mass per 100 g of dry substrate mass was an the substrate, containing 25 % of biohumus and 75 % of wheat straw. The possible cause of this effect could arise from increasing phosphorus content in the substrate. The hughest growth rate of champignon mycelium was 2.2-2.4 mm/day on the substrate, containing 94-96 % of wheat grains and 4-6 % of biohumus.

Fungistatic Activity of Engineered Nanoparticles / A. A. Asanova [et al.] // Nanotechnologies Russ. - 2018. - Vol. 13, Is. 5-6. - P277-280, DOI 10.1134/S1995078018030023 . - ISSN 1995-0780

Аннотация: The influence of various concentrations of Ag, TiO2, and SiO2 nanoparticles on conidia germination of the phytopathogenic fungus Bipolaris sorokiniana and mycelium growth of the xylotrophic fungi Pleurotus ostreatus and Neonothopanus nambi was analyzed. It is established that a decrease in conidia germination of phytopathogenic fungus and mycelium growth of the xylotrophic fungi occurs at relatively high silver nanoparticle concentrations. The appropriate ЕС50 values for Bipolaris sorokiniana, Pleurotus ostreatus, and Neonothopanus nambi are found to be 30, 14, and 31 mg/dm3, respectively. No effect of various concentrations of TiO2 and SiO2 nanoparticles on the studied cultures of fungi is highlighted. Thus, the negative impact of nanosilver on the growth of fungi at a high concentration which is untypical for objects of the environment and a lack of this influence of titanium dioxide and silica nanoparticles testifies to the high resistance of mycelial forms of organisms to engineered nanoparticles. © 2018, Pleiades Publishing, Ltd.

Growing of Pleurotus florida on substrates with inedible potato biomass [Текст] / N. S. Manukovsky, V. S. Kovalev, I. V. Gribovskaya // Mikol. Fitopatol. - 2002. - Vol. 36, Is. 4. - P. 48-54. - Cited References: 14 . - ISSN 0026-3648

РУБ Mycology

Аннотация: The possibility to grow oyster mushroom Pleurotus florida Fovose on the substrate prepared from inedible potato biomass was tested. It was shown that mycelium growth rate was increased by 61-69 % after boiling or soaking of inedible potato biomass and mixing it with wheat straw. The increase in growth rate can be accounted for the decrease of potassium content in the substrate from 5,53 % to 0.87-0.88 %. Mixing inedible potato biomass with wheat straw has had a positive impact on the oyster mushroom fruiting and the convertion of spent mushroom compost into biohumus.

Mass exchange in an experimental new-generation life support system model based on biological regeneration of environment / A. A. Tikhomirov [et al.] // Advances in Space Research. - 2003. - Vol. 31, Is. 7. - P1711-1720, DOI 10.1016/S0273-1177(03)80017-0 . - ISSN 0273-1177

Аннотация: An experimental model of a biological life support system was used to evaluate qualitative and quantitative parameters of the internal mass exchange. The photosynthesizing unit included the higher plant component (wheat and radish), and the heterotrophic unit consisted of a soil-like substrate, California worms, mushrooms and microbial microflora. The gas mass exchange involved evolution of oxygen by the photosynthesizing component and its uptake by the heterotroph component along with the formation and maintaining of the SLS structure, growth of mushrooms and California worms, human respiration, and some other processes. Human presence in the system in the form of "virtual human" that at regular intervals took part in the respirative gas exchange during the experiment. Experimental data demonstrated good oxygen/carbon dioxide balance, and the closure of the cycles of these gases was almost complete. The water cycle was nearly 100% closed. The main components in the water mass exchange were transpiration water and the watering solution with mineral elements. Human consumption of the edible plant biomass (grains and roots) was simulated by processing these products by a unique physicochemical method of oxidizing them to inorganic mineral compounds, which were then returned into the system and fully assimilated by the plants. The oxidation was achieved by "wet combustion" of organic biomass, using hydrogen peroxide following a special procedure, which does not require high temperature and pressure. Hydrogen peroxide is produced from the water inside the system. The closure of the cycle was estimated for individual elements and compounds. Stoichiometric proportions are given for the main components included in the experimental model of the system. Approaches to the mathematical modeling of the cycling processes are discussed, using the data of the experimental model. Nitrogen, as a representative of biogenic elements, shows an almost 100% closure of the cycle inside the system. The proposed experimental model of a biological system is discussed as a candidate for potential application in the investigations aimed at creating ecosystems with largely closed cycles of the internal mass exchange. The formation and maintenance of sustainable cycling of vitally important chemical elements and compounds in biological life support systems (BLSS) is an extremely pressing problem. To attain the stable functioning of biological life support systems (BLSS) and to maintain a high degree of closure of material cycles in them, it is essential to understand the character of mass exchange processes and stoichiometric proportions of the initial and synthesized components of the system.

Utilization of substrate when growing oyster mushroom Pleurotus florida Fovose [Текст] / N. S. Manukovsky, V. S. Kovalev, I. V. Gribovskaya // Mikol. Fitopatol. - 1998. - Vol. 32, Is. 6. - P. 43-46. - Cited References: 8 . - ISSN 0026-3648

Аннотация: Content of biogenic elements in the residual substrate after growing of oyster mushroom Pleurotus florida Fovose on wheat straw was studied. It was calculated, that masses of sulphur, calcium and magnesium in the residual substrate were more than 90 % of their initial masses in wheat straw used for growing. Therefore the accumulation of these elements in the substrate under its repeated recycling for mushroom growing is possible. On the contrary the lack of phosphorus is expected. After washing content of all biogenic elements tested in residual substrate, except for calcium, was lower than their content in wheat straw. The decreasing of mushroom yield under increasing rate of residual substrate in its mixture with wheat straw was shown. Washing of residual substrate did not lead to decreasing of yield.
