Аннотация: The study addresses the effect of humic substances on marine luminous bacteria Photobacterium phosphoreum exposed to Am-241 (3,000 Bq L -1, water solution). Luminescent intensity of the bacteria was applied as a marker of their physiological activity. Humic substances have been found to reduce the effect of Am-241 on luminescence, decrease damage to cells, and change distribution of Am-241 between bacterial cells and intercellular media. It was shown that water-soluble humic substances, being products of natural transformation of organic substances in soil and bottom sediments, can serve as protecting agents for water microorganisms exposed to alpha radionuclides.

Аннотация: The source of radioactive contamination of the Yenisei River floodplain, including contamination with transuranic elements, is the Mining-and-Chemical Combine of the Russian Ministry of Atomic Energy, which has for many years been producing weapons-grade plutonium. Transuranic elements have been detected not only in the soil and sediment of the river but also in the biomass of aquatic plants. This work is an investigation of accumulation and release of 241Am by a submerged macrophyte of the Yenisei River (Elodea canadensis) in laboratory experiments. In 2000-2003, laboratory experiments were carried out with biomass of E. canadensis Mich. and filtered river water. The samples were collected from the Yenisei River upstream of the discharge of the Combine's radioactive effluent. The experiments showed that 241Am is accumulated by Elodea biomass: the activity concentration of 241Am can reach 3280 В± 240 Bq/g, with the concentration factor for 241Am 16 600 В± 2200 l/kg. Results of chemical fractionation have proved that in the course of 241Am accumulation by Elodea biomass, 241Am tightly bound to biomass increases from 11% to 27% of the total 241Am in the biomass. Release of 241Am from the decaying Elodea biomass has been evaluated experimentally. By the end of the experiment (lasting up to 127 days), the Elodea plants had lost up to 65% of their initial 241Am activity and the rate of 241Am release into the water environment reached 23 Bq/day.

Аннотация: A short survey and critical analysis of previously proposed criteria for growth control of populations of microorganisms in the chemostat are presented. Based on the analysis of a mathematical model of the steady-state of a microbial population in the chemostat, an adequate control criterion is suggested, along with a method to identify the corresponding regulating factors. The new control criterion is expressed as a product of the factor transformation coefficient and the biomass sensitivity coefficient (SC) with respect to the change of the factor at the chemostat inlet (referred to in the sequel as the biomass SC). The control criterion determines the strength of the control exerted by this or that factor. The method of determination of the regulating factors consists in experimental determination of the real SCs for factors and the biomass and in calculating on this basis the corresponding ideal SCs for constant factor transformation coefficients. The ideal SCs are shown to add up to an integer value, a constraint that we call "quantization" relationships. Such relationships are used to test the completeness of the drawn list of control factors. The proposed method was applied to our own and literature data.

Аннотация: Physiological-biochemical, genetic, and cultural properties of the glucose-utilizing mutant strain Ralstonia eutropha B8562 have been compared with those of its parent strain R. eutropha B5786. It has been shown that growth characteristics of the strain cultured on glucose as the sole carbon and energy source are comparable with those of the parent strain. Strain B8562 is characterized by high polyhydroxyalkanoate (PHA) yields on different carbon sources (CO(2), fructose, and glucose). PHA accumulation in the strain batch cultured on glucose under nitrogen deficiency reaches 90 %. The major monomer in the PHA is beta-hydroxybutyric acid (more than 99 mol %); the identified minor components are beta-hydroxyvaleric acid (0.25-0.72 mol %) and beta-hydroxyhexanoic acid (0.08-1.5 mol %). The strain is a promising PHA producer on available sugar-containing media with glucose.

Аннотация: The study was done to investigate the content of manmade radionuclides in aquatic organisms of the Yenisei River near the Mining-and-Chemical Combine (MCC) and to estimate the exposure dose rates to organisms from various sources. The results of the investigation and calculations suggest that the main source of radioactive contamination of aquatic organisms is the coolant of the third MCC reactor, which is still being released into the Yenisei. Gamma-spectrometric analysis revealed 23 manmade radionuclides in the biomass of aquatic plants. The aquatic animal Phylolimnogammarus viridis and diatoms also contain manmade radionuclides. Among aquatic organisms, the highest dose rate is received by aquatic plants (up to 39 ?Gy/day). For most aquatic organisms under study, the dose received from the technogenic irradiation is an order of magnitude higher than the dose received from natural irradiation. The water moss (Fontinalis antipyretica) features the highest capacity to accumulate manmade radionuclides; hence, it accumulates the largest technogenic exposure dose among the study aquatic organisms.

Аннотация: Bioregenerative life-support systems (BLSS) are studied for developing the technology for a future biological life-support system for long-term manned space missions. Ways to utilize human liquid and solid wastes to increase the closure degree of BLSS were investigated. First, urine and faeces underwent oxidation by Kudenko's physicochemical method. The products were then used for root nutrition of wheat grown by the soil-like substrate culture method. Two means of eliminating sodium chloride, introduced into the irrigation solution together with the products of urine oxidation, were investigated. The first was based on routine electrodialysis of irrigation water at the end of wheat vegetation. Dialysis eliminated about 50% of Na from the solution. This desalinization was performed for nine vegetations. The second method was new: after wheat cultivation, the irrigation solution and the solution obtained by washing the substrate containing mineral elements not absorbed by the plants were used to grow salt-tolerant Salicornia europaea L. plants (saltwort). The above-ground biomass of this plant can be used as a food, and roots can be added to the soil-like substrate. Four consecutive wheat and Salicornia vegetations were cultivated. As a result of this wheat and Salicornia cultivation process, the soil-like substrate salinization by NaCl were considerably decreased. В© 2008 Humana Press.

Аннотация: Wheat was cultivated on soil-like substrate (SLS) produced by the action of worms and microflora from the inedible biomass of wheat. After the growth of the wheat crop, the inedible biomass was restored in SLS and exposed to decomposition ("biological" combustion) and its mineral compounds were assimilated by plants. Grain was returned to the SLS in the amount equivalent to human solid waste produced by consumption of the grain. Human wastes (urine and feces) after physicochemical processing turned into mineralized form (mineralized urine and mineralized feces) and entered the plants' nutrient solution amounts equal to average daily production. Periodically (once every 60-70 days) the nutrient solution was partly (up to 50%) desalinated by electrodialysis. Due to this NaCl concentration in the nutrient solution was sustained at a fixed level of about 0.26%. The salt concentrate obtained could be used in the human nutrition through NaCl extraction and the residuary elements were returned through the mineralized human liquid wastes into matter turnover. The control wheat cultivation was carried out on peat with use of the Knop nutrient solution. Serial cultivation of several wheat vegetations within 280 days was conducted during the experiment. Grain output varied and yield/harvest depended, in large part, upon the amount of inedible biomass returned to SLS and the speed of its decomposition. After achieving a stationary regime, (when the quantity of wheat inedible biomass utilized during vegetation in SLS is equal to the quantity of biomass introduced into SLS before vegetation) grain harvest in comparison with the control was at most 30% less, and in some cases was comparable to the control harvest values. The investigations carried out on the wheat example demonstrated in principle the possibility of long-term functioning of the LSS photosynthesizing link based on optimizations of biological and physicochemical methods of utilization of the human and plants wastes. The possibilities for the use of these technologies for the creation integrated biological-physicochemical LSS with high closure degree of internal matter turnover are discussed in this paper.

Аннотация: The paper considers problems of biosynthesis of higher plants' biomass and "biological incineration" of plant wastes in a working physical model of biological LSS. The plant wastes are "biologically incinerated" in a special heterotrophic block involving Califomian worms, mushrooms and straw. The block processes plant wastes (straw, haulms) to produce soil-like substrate (SLS) on which plants (wheat, radish) are grown. Gas exchange in such a system consists of respiratory gas exchange of SLS and photosynthesis and respiration of plants. Specifics of gas exchange dynamics of high plants - SLS complex has been considered. Relationship between such a gas exchange and PAR irradiance and age of plants has been established. Nitrogen and iron were found to the first to limit plants' growth on SLS when process conditions are deranged. The SLS microflora has been found to have different kinds of ammonifying and denitrifying bacteria which is indicative of intensive transformation of nitrogen-containing compounds. The number of physiological groups of microorganisms in SLS was, on the whole, steady. As a result, organic substances - products of exchange of plants and microorganisms were not accumulated in the medium, but mineralized and assimilated by the biocenosis. Experiments showed that the developed model of a man-made ecosystem realized complete utilization of plant wastes and involved them into the intrasystem turnover.

Аннотация: The chromatographic conditions presented allowed the separation of the nitrophenacyl derivatives of standards of eleven free fatty acids (FFA) using a portable high-performance chromatograph, suitable for use aboard a research vessel. A statistically significant linear correlation between UV absorbance and amount of the analytes injected was obtained. The method was tested on FFA from algae cultural media. The method can be used for the ecological monitoring of natural waters.

Bioluminescence of bacteria: a rhythmic process / L. Y. Berzhanzkaya, I. I. Gitel'zon, A. M. Fish // BIOPHYSICS. - 1973. - Vol. 18, Is. 2. - P293-301 . - ISSN 0006-3509

Аннотация: New results obtained in the detection of rhythms in the low frequency range in the light signal of a small number of photo bacteria are reported. The luminescence of a small number of bacteria was recorded with an apparatus the sensitivity of which was 12 quanta/pulse. To check the possible rhythms in the luminescence of the bacteria, correlation analysis was made of the interpulse intervals of the detection of the signal with a computer. This revealed a definite rhythm in the bacterial luminescence the fundamental frequency of which lies in the region 8 c/s. Profound modulation of a bioluminescent signal at this and multiple frequencies was demonstrated. The harmonic components found in the spectrum of the signal refute the existing view of the continuous character of bacterial luminescence.

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).

Impaired growth of plants cultivated in a closed system: Possible reasons / J. I. Gitelson [et al.] // Advances in Space Research. - 1997. - Vol. 20, Is. 10. - P1927-1930 . - ISSN 0273-1177

Аннотация: Plants in experiments on "man-higher plants" closed ecosystem (CES) have been demonstrated to have inhibited growth and reduced productivity due to three basic factors: prolonged usage of a permanent nutrient solution introduction into the nutrient medium of intra-system gray water, and closure of the system. Gray water was detrimental to plants the longer the nutrient solution was used. However, higher plant growth was mostly affected by the gaseous composition of the CES atmosphere, through accumulation of volatile substances. В© 1997 COSPAR. Published by Elsevier Science Ltd.
