Аннотация: The growth of the carboxydobacterium Seliberia carboxydohydrogena Z-1062 was studied at a different concentration of mineral elements under the conditions of continuous turbidostat cultivation. The chemical composition of the bacterium was determined and the dynamics of its specific growth rate and the intracellular content of mineral elements were studied when the concentration of these elements was changed in the growth medium. The synthesis of 1 g of biomass by this strain required: N, 120 mg; P, 23 mg; S, 5.5 mg; K, 1.5 mg; Mg, 3.5 mg. Changes in the residual concentrations of the elements within a broad range had no effect on the specific rate of the carboxydobacterial growth and chemical composition.

Аннотация: We describe the experimental system having maximal possible closure of material recycling in an ecosystem, including people and plants, which was carried out in a hermetically sealed experimental complex "BIOS-3", 315 m2 in volume. The system included 2 experimentators and 3 phytotrons with plants (total sowing area of 63 m2). Plants were grown with round-the-clock lamp irradiation with 130 Wm-2 PAR intensity. The plants production was food for people. Water exchange of ecosystem, as well as gas exchange, was fully closed excluding liquids and gas samples taken for chemical analysis outside the system. The total closure of material turnover constituted 91%. Health state of the crew was estimated before, during and after the experiment. A 5-months period did not affect their health. The experiments carried out prove that the closed ecosystem of "man-plants" is a prototype of a life-support system for long-term space expeditions. В© 1989.

A NEW EXPERIMENTAL-METHOD TO REVEAL DENSITY-DEPENDENT CHEMICAL FACTORS INVOLVED IN MICROBIAL-POPULATION GROWTH-CONTROL [Text] / A. G. DEGERMENDZHI, V. V. ADAMOVICH, V. A. ADAMOVICH // Microbiology. - 1993. - Vol. 62, Is. 3. - P308-313. - Cited References: 11 . - 6. - ISSN 0026-2617

РУБ Microbiology

Аннотация: Experiments based on an earlier developed theory with a culture of Escherichia coli 0-124 were undertaken to determine the feedback strength (FBS) in growth control. FBS is defined as the change in growth acceleration brought about by a discontinuous reduction in microbial concentration under conditions of constant chemical composition of the medium, and is an over-all measure of the regulatory influence of all chemical factors dependent on biomass concentration. FBS was determined for batch cultivation with glucose. In various growth phases the culture was diluted by its own filtrate and then the change in growth acceleration as compared to the control was measured. FBS was reliably different from zero at the end of the exponential phase and in the phase of decelerated growth and was of the order of -20 to -200 (h.g/liter)(-1). The feedback component due to glucose alone was estimated using the obtained relation between specific growth rate and glucose concentration (mu(max) = 0.55 +/- 0.05 h(-1), K-s = 2.5 +/- 0.7 mg/liter). The glucose-dependent regulatory contribution to FBS was found to be as low as 0.5 to 40%, which suggests the presence of other growth control factors. Upon accuracy improvements, this method may develop into an accepted microbiological tool for identifying major density-dependent factors involved in microbial growth control.

Аннотация: The examination of four species of luminous bacteria Photobacterium leiognathi, Photobacterium phosphoreum, Vibrio fischeri and Vibrio harveyi has enabled us to reveal some nutrient medium components effecting growth, luminescence intensity and luciferase synthesis. These agents are nucleic components (nucleotides, nucleotides and amine bases), amino acids and vitamins, which are part of hydrolysates from the biomass of various lithotrophic microorganisms, hydrogen-oxidizing, iron-oxidizing and carboxydobacteria. The effect of promoting agents essentially alters the physiological state and ultrastructure of the cells of luminous bacteria and increases luciferase biosynthesis two- to three-fold compared to a control.

EXPERIMENTAL-MODEL OF A GAS-CLOSED AUTOTROPH HETEROTROPH ECOSYSTEM [Text] / T. I. PISMAN [et al.] // Microbiology. - 1995. - Vol. 64, Is. 5. - P560-562. - Cited References: 7 . - ISSN 0026-2617

РУБ Microbiology

Аннотация: The dynamics of components were studied in a gas-closed autotroph-heterotroph ecosystem with spatially separated components. Oxygen-producing green microscopic algae served as the autotrophic component, and carbon dioxide-producing yeasts served as the heterotrophic component. The longevity of the gas-closed autotroph-heterotroph system was two times greater than that of separately cultivated components. Making the system more closed by additing glucose (the limiting factor for heterotroph growth) prolonged the longevity of the system up to 25 days. Further system closing by complicating the heterotrophic component (comprised now of two yeast species differing in the rate of substrate consumption) further increased the longevity of the system and the biomass of both the autotrophic and heterotrophic components.

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.

Effect of the intracellular poly-?-hydroxybutyrate pool on the growth of a hydrogen-oxidizing bacterium under nonoptimum conditions / T. G. Volova, G. S. Kalacheva, A. P. Puzyr // Mikrobiologiya. - 1996. - Vol. 65, Is. 5. - P594-598 . - ISSN 0026-3656
Аннотация: -Growth of the hydrogen-oxidizing bacterium Alcaligenes eutrophus under nonoptimum conditions (acidic and alkaline pH, elevated and lowered temperatures, absence of exogenous sources of carbon and energy) was studied in relation to the initial intracellular concentration of poly-?-hydroxybutyrate (PHB), which varied from virtually zero, to 60-70% of the dry biomass. An initial PHB pool of greater than 30-40% provided for a 2- to 2.5-fold higher biomass yield in acidic and alkaline media or at nonoptimum temperatures as compared with cultures initially containing no pommer. The intracellular PHB pool also provides for the growth of the culture in the absence of exogenous carbon sources and its survival (without growth) with no exogenous energy supply.

Аннотация: Measurements of trace elements incoming and exiting ''Bios-3'' biological-engineering life support system evidence presence of a source of these elements inside the system. This source is, most probably, structural units (steel walls, hose rubber, plastic coatings), catalysts of the thermal catalytic incinerator, expanded clay aggregate mechanically fixing plants and so on. The trace elements are received by the nutrient solutions and build up in the plant biomass. As a consequence the crew may receive elevated doses of such trace elements as aluminum, lead, nickel, chromium. To reduce income of trace elements to LSS requires thorough selection and preliminary treatment of structural materials with reduced desorption capacities and running-in of the system in idle mode prior to exploitation. This mode involves operation of the engineering part of the system (without plants and humans, but with nutrient solutions) for several months.

Аннотация: A simple fluorometric method is proposed for rapid determination of the concentration or biomass of bacterioplankton in various natural freshwater reservoirs and streams directly under field conditions. Fluorescamine, which specifically binds to proteins and amino acids in microbial cells, was used as the fluorescent marker. Regression equations were calculated on the basis of the results obtained. The coefficient of correlation between the fluorescence intensity and the bacterial biomass (cell number) was found to be 0.93 (0.89) for the total body of data obtained in the reservoirs studied.

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.

Mineralization of wastes of human vital activity and plants to be used in a life support system [Text] / Y. A. Kudenko, I. V. Gribovskaya, R. A. Pavlenko // Acta Astronaut. - 1997. - Vol. 41, Is. 3. - P. 193-196, DOI 10.1016/S0094-5765(97)00215-4. - Cited References: 8 . - ISSN 0094-5765

РУБ Engineering, Aerospace

Аннотация: Available methods for mineralizing wastes of human activity and inedible biomass of plants used in this country and abroad are divided into two types: dry mineralization at high temperatures up to 1270 K with subsequent partial dissolution of the ash and the other-wet oxidation by acids. In this case mineralization is performed at a temperature of 470-460 K and a pressure of 220-270 atmospheres in pure oxygen with the output of mineral solution and dissoluble sediments in the form of scale. The drawback of the first method is the formation of dioxins, CO, SO2, NO2 and other toxic compounds. The latter method is too sophisticated and is presently confined to bench testing. The here proposed method to mineralize the wastes is in mid-position between the thermal and physical chemical methods. At a temperature of 89-90 degrees C the mixture was exposed to a controlled electromagnetic field at normal atmospheric pressure. The method merits simplicity, reliability, produces no dissoluble sediment or emissions noxious for human and plants. The basic difference from the above said methods is to employ as an oxidizer atomic oxygen, its active forms including OH-radicals with hydrogen peroxide as the sourer. Hydrogen peroxide can be produced with electric power from water inside the Life Support System (LSS). (C) 1998 Elsevier Science Ltd. All rights reserved.

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: Dynamics of active sludge microorganism activity in aerotanks under chemostat conditions has been studied. Dependence of microorganism catalase activity has been found to depend on residual substrate concentration in proportion to the biomass of microorganisms. Experimental data and field observations has formed the basis to develop a technique to evaluate in relative units the amount of the substrate consumed by biocenosis of the active sludge in the air tanks of purification facilities.

Аннотация: The influence of two rhizosphere bacteria-Pseudomonas fluorescens and Pseudomonas putida-on 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.
