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: Создана экспериментальная модель замкнутой экосистемы "продуцент-консумент" (Chlorella vulgaris-Paramecium caudatum) с пространственно разделенными звеньями. Данная экосистема существовала около 7 мес. В течение 60 сут численность звеньев достигала стационарного состояния. Исследована динамика трех форм азотистых соединений: азота в аммонийной, нитратной и нитритной формах. Показана роль хищника в круговороте азота, выявлена прямая зависимость между размножением простейших и выделением ими азота в аммонийной форме, к-рая наиболее предпочтительна для роста хлореллы. Обнаружено появление и монотонное увеличение конц-ии азота в нитритной форме от 0 до 300 мг/л. Предполагается, что данная форма азота является продуктом метаболизма клеток хлореллы, не доступным ни их собственным ферментам, ни ферментам сопутствующей микрофлоры.

Аннотация: Experimental and theoretical models of closed 'autotroph-heteretroph' (chlorella-yeast, chlorella- protozoa) ecosystems with spatially separated components have been created and studied. The chart of flows and interaction of components of gas-closed 'chlorella-yeast' system have formed the basis describe mathematically the functioning of the given system, experimental results have been found to agree with computer solution of the problem in terms of quality. Investigation of the experimental model of the 'producer-consumer' trophic chain demonstrated the role of protozoa in nitrogen turnover. 'Production-decomposition' and 'production-grazing-decomposition' cycle models has been theoretically analyzed and compared. The predator has been shown to be a more intensive mineralizer than the reducer component.

Аннотация: На примере накопительных культур Chlorella vulgaris и Spirulina platensis впервые установлено, что состав внеклеточных СЖК синезеленой водоросли зависел от т-ры роста и изменялся в основном за счет увеличения в среде ненасыщенных к-т при повышенной т-ре, хотя в липидах мембран при этой т-ре степень ненасыщенности жирных к-т существенно снижалась. Состав внеклеточных СЖК зеленой водоросли оставался неизменным при исследованных т-рах, несмотря на снижение содержания триеновых кислот в клеточных липидах при повышенной т-ре. Предполагается, что прокариотические микроводоросли могут использовать дополнительный регуляторный механизм состава мембран за счет выброса избытка определенных жирных к-т, в эукариотных клетках этот механизм не реализуется. Состав внеклеточных СЖК зеленой и синезеленой водоросли был сходным, что могло быть обусловлено метаболическим сходством жирнокислотного синтеза C. vulgaris с таковым прокариотических водорослей.

Аннотация: Experimental models of small biotic cycles of different degree of closure and complexity with spatially separated components based on unicellular organisms have been studied. Gas closure of components looped into "autotroph-heterotroph" (chlorella-yeast) system doubled the lifetime of the system (as opposed to individually cultivated components). Higher complexity of the heterotroph component consisting of two yeast species also increased the lifetime of the system through more complete utilization of the substrate by competing yeast species. The lifetime of gas and substrate closed "producer-consumer" trophic chain (chlorella-paramecia) increased to 7 months. In 60 days the components' numbers reached their steady state followed by more than 40 cycles of the medium. The role of a predator organism (protozoan) in nitrogen cycling was demonstrated; reproduction of protozoa correlated directly with their emission of nitrogen in the ammonia form that is most optimum for growth of chlorella.

Аннотация: The growth and development of Brachionus plicatilis (Muller), a rotifer and one of the most abundant zooplankton species in Lake Shira, a saline lake at low temperature in the Republic of Khakassia, was studied in cultures at different trophic conditions. Growth indices were evaluated at natural (lake) concentrations of bacteria, Chlorella vulgaris, a microalga, and Candida utilis, a yeast. The negative effect on rotifer reproduction in the algal-bacterial community by blue-green algae was demonstrated. The ratio of ontogenetic periods was shown to be in accord with species and food concentration. Base values required to calculate B. plicatilis population simulation model parameters were defined.

With increasing growth temperature, the degree of unsaturation of the intracellular FAs of both algae decreased, while that of the extracellular FFAs of S. platensis increased. The composition of the extracellular FFAs of C vulgaris practically did not depend on the growth temperature.

Paramecium bursaria -- endosymbiosis -- matter exchange cycle
Аннотация: A hypothesis is considered that the establishment and maintenance of mass exchange processes in the Paramecium bursaria symbiotic complex (infusorian-alga) depends on the presence of the third component-bacteria-whose role is underestimated but essential for completing the exchange cycle. The role of this component in the symbiotic cycle of Paramecium bursaria is possible to reveal using special bactericidal preparations specifically inhibiting the bacteria involved in the metabolic cycle but having no effect on the functions of the host cell and the zoochlorella population. Experiments with various preparations of this type were performed, and the response to treatment was estimated from growth rates of the symbiotic complex and its components. This allowed identification of an antibiotic (rifampicin) that had no adverse influence on free-living zoochlorella and chlorella-free paramecia (the basic components of the symbiotic cycle) but drastically inhibited the growth of the P. bursaria symbiotic complex, which could be interpreted as evidence in favor of the hypothesis concerning the existence of the third symbiotic component.

Аннотация: A hypothesis is considered that the establishment and maintenance of mass exchange processes in the Paramecium bursaria symbiotic complex (infusorian-alga) depends on the presence of the third component-bacteria-whose role is underestimated but essential for completing the exchange cycle. The role of this component in the symbiotic cycle of Paramecium bursaria is possible to reveal using special bactericidal preparations specifically inhibiting the bacteria involved in the metabolic cycle but having no effect on the functions of the host cell and the zoochlorella population. Experiments with various preparations of this type were performed, and the response to treatment was estimated from growth rates of the symbiotic complex and its components. This allowed identification of an antibiotic (rifampicin) that had no adverse influence on free-living zoochlorella and chlorella-free paramecia (the basic components of the symbiotic cycle) but drastically inhibited the growth of the P. bursaria symbiotic complex, which could be interpreted as evidence in favor of the hypothesis concerning the existence of the third symbiotic component.
