The vertical structure of a pelagic community in the tropical ocean / M. E. Vinogradov, I. I. Gitelzon, Yu. I. Sorokin // Marine Biology. - 1970. - Vol. 6, Is. 3. - P187-194, DOI 10.1007/BF00347226 . - ISSN 0025-3162
Аннотация: The vertical structure of the ecosystem in the euphotic zone of the western Equatorial Pacific has been studied. The studies were based on a continuous sounding of the bioluminescence field, with simultaneous, vertically aimed sampling made with the aid of a 5l water bottle and plankton nets. The bioluminescence field has a two-maxima structure with a more pronounced and permanent lower maximum found in the oligotrophic regions as deep as 60 to 100 m. In the narrow (10 m) layer of maximum bioluminescence, the concentration of zooplankton, as well as the concentration, activity and production of bacteria and phytoplankton, are several times higher than those in immediately adjacent waters at greater or lesser depth. At the same time, the concentration of nutrient salts in that layer diminishes sharply and approaches zero in the overlying water. Analysis of the data obtained shows that the production processes above the lower maximum layer are dependent not only on the turbulent influx of nutrient salts from the underlying layers, but also on the horizontal supply from the zone of upwelling. A pelagic community, in its different time aspects from the moment of water ascending until its sinking in the convergence zone, is suggested as a common system for modelling.

Theoretical and experimental decisions in the creation of an artificial ecosystem for human life support in space. / L. V. Kirensky [et al.] // Life sciences and space research. - 1971. - Vol. 9. - P75-80 . - ISSN 0075-9422

Аннотация: All of man's former space flights were not real ventures into space in the biological sense, as his life was supported with unregenerated earth supplies. The coming stage of space exploration requires man's long existence in the cosmos and on the other planets. This stage of man's activity outside the earth become possible only by creating small man-made ecosystems, permitting the support of his metabolism by the recycling of substances of the terrestrial biosphere. Creation of such systems is a new scientific and technical task. Man-made ecosystems are a new product of man's activity, which have no complete analogy, either in nature, or in technology. Stochastic mechanisms, which stabilize biogeocenosis, cannot be effective in small ecosystems. A technique of parametric control over biosynthesis made it possible to calculate, and put to practice, an ecosystem for man with a cyclic regeneration of the atmosphere, water and, partially, food. The specific bio-technological properties of small man-made ecosystems are being analysed. The possibility of their application for man's excursions into space and for the settlement of other planets is being considered.

Life support system with autonomous control employing plant photosynthesis / I. I. Gitelson [et al.] // Acta Astronautica. - 1976. - Vol. 3, Is. 9-10. - P633-650 . - ISSN 0094-5765

Аннотация: This research was aimed at obtaining a closed control system. This was achieved by placing all the technological processes providing for human vital activities within the hermetically sealed space, and by transferring the entire control and guidance of these processes to people inhabiting the system. In contrast to existing biological life support systems, man has been included not only as a participant of metabolism, but as an operator who is the central figure in collecting information, making decisions and controlling all technological processes. To tackle this problem, the "BIOS-3" experimental complex was created for performing long-term experiments using different structures of biological life-support system. The experiment lasted six months and consisted of three stages. During the first stage the system was comprised of two equivalent phytotrons with the culture of wheat and an assortment of vegetable plants, and the living compartment. At the second stage, one of the phytotrons was removed while a compartment of chlorella cultivators was introduced. The third stage differed from the second, the former using wheat phytotron and the latter employing phytotron with an assortment of vegetable cultures. Three men inhabited the system simultaneously. The experiment demonstrated that a biological life support system controlled autonomously from the inside is feasible within a small confined space. However, immunological and microbiological research shows, that the medium created by the system is not fully adequate for man. In conclusion, some prospects have been outlined for further studies of biological life support systems. В© 1976.

Аннотация: Исследованы амфифильные свойства бакт. люциферазы в различных условиях и ее взаимодействие с длинноцепоч. алифатич. альдегидом и соответствующей жирной к-той. Методом малоуглового рассеяния рентген. лучей определены радиусы инерции фермента в р-ре и найдены зависимости их от состояния люциферазы. Исследована реология монослоев, полученных из белка, субстрата, продукта и их комбинаций со строго определенными соотношениями на поверхности различных субфаз. Соответствующие 'пи'-А изотермы показывают, что во всех случаях образуются твердые двумерные пленки, сжимаемость к-рых сильно зависит от соотношения компонент. Монослои перенесены на твердую подложку и получены мультислойные пленки на разных носителях. Рентгеновское исследование позволило определить ближний порядок в толстых пленках, к-рый также зависит от соотношения компонент. Метод позволяет конструировать регулярные неоднородности распределения люциферазы в монослое. Результаты электр. микроскопии чистых и смешанных ионо- и бислоев, перенесенных на твердые подложки, свидетельствуют в пользу микроэмульсионной модели амфифильности люциферазы. Получены ленгмюровские пленки с сохранением активности. Это открывает путь к новому поколению люциферазных твердотельных биосенсоров. Библ. 21

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.

Аннотация: The inhibition of bacterial luminescence has been used in testing industrial enterprises sewage. The toxicity of the sewage is less than the total toxicity of separate components due to neutralization of quinone products of polyphenol oxidation in the reactions with the other phenol components of sewage. Toxicity increase is due to their influence on the cell membrane. Studies of cell ultrastructure confirm this fact. The studied mechanism of the complex effect allowed a more accurate forecast of the ecological situation during the discharge of phenol compounds and metals. It also showed the necessity of taking into account the complex effect of sewage components on contaminant discharge into water reservoirs.

Аннотация: Using experimental microecosystems the kinetics of phenol disappearance in river and reservoir water were investigated. In river water the disappearance kinetics could be described by A first-order equation, the same kinetics took place in reservoir water before and after the period of ''bloom'' of blue-green algae. During the ''bloom'', the phenol seemed to be mineralized by bacteria which grew at the expense of another compound, and the model of best fit was the model of exponential growth and low concentration of the test substrate. In the river, two sections differed according to the difference between the mean values of the specific disappearance rates. In the reservoir these rates were lower than those in the river. In general the specific disappearance rate values did not correlate with the values of initial bacterioplankton density, the concentrations of inorganic nutrients nor the chemical oxygen demand. Conclusions about the integral influence of ecosystems on the disappearance rates and dependence of self-purification kinetics on the type of aquatic ecosystem were made.
