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: Изучен состав внеклеточных свободных жирных к-т (СЖК) и внутриклеточных жирных к-т (ЖК) в накопительных культурах водорослей - прокариотической Spirulina platensis и эукариотической Chlorella vulgaris, выращенных при пониженной, повышенной и оптимальной температурах. Состав внутриклеточных ЖК у обоих видов изменялся в зависимости от т-ры по обычно наблюдаемой схеме: степень ненасыщенности уменьшалась с повышением т-ры. Состав внеклеточных СЖК у прокариотической S. platensis изменялся противоположным образом: степень их ненасыщенности с увеличением т-ры увеличивалась. В то же время, т-ра не оказывала достоверного влияния на состав внеклеточных СЖК эукариотической C. vulgaris. Ил. 2. Табл. 3. Библ. 19

Аннотация: Исследовали влияние т-ры среды на состав внутриклеточных жирных к-т липидов и выделение в среду свободных жирных к-т (СЖК) у цианобактерии (Spirulina platensis) и эукариотических (Chlorella vulgaris и Botryococcus braunii) микроводорослей в условиях периодических лабораторных культур. Установлено, что температурная реакция внутриклеточного состава ЖК была схожей у всех изученных видов: независимо от их таксономического положения при повышении т-ры относительное содержание более ненасыщенных ЖК уменьшалось. При этом, у прокариотического вида повышение т-ры вызывало подавление элонгации 16:0 в 18:0 и их дальнейшей десатурации, а у эукариотических видов - снижение десатурации диеновых кислот до триеновых. В противоположность эукариотическим видам, у S. platensis с повышением т-ры соотношение диеновых и триеновых к-т практически не менялось. Для эукариотических водорослей достоверного влияния температурного фактора на состав внеклеточных СЖК обнаружено не было. В то же время у цианобактерий S. platensis относительное содержание ненасыщенных внеклеточных СЖК при повышении т-ры увеличивалось. Ил. 2. Табл. 3. Библ. 31

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.

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.

Stable isotope fractionation of fatty acids of Daphnia fed laboratory cultures of microalgae / M. I. Gladyshev [et al.] // Limnologica. - 2016. - Vol. 56. - P23-29, DOI 10.1016/j.limno.2015.12.001 . - ISSN 0075-9511

Аннотация: We tested a comparatively new method of tracing of natural food webs, compound-specific isotope analysis (CSIA) of fatty acids (FA), using laboratory culture of Daphnia galeata fed Chlorella vulgaris and Cryptomonas sp. In general, Daphnia had significantly lighter carbon stable isotope composition of most fatty acids, including essential, than those of their food, microalgae. Thus, our results did not support the pivotal premise of the FA-CSIA application for food web analysis, i.e., transmitting the isotope 'signal' of essential FAs to consumers from their food without any modification. Moreover, the values of isotope fractionation of particular FAs in the consumer relative to its food were not constant, but varied from 1.35‰ to 7.04‰. The different isotope fractionation (depletion) values of diverse FAs in consumer were probably caused by different processes of their synthesis, catabolism and assimilation. More work is evidently to be done for correct interpretation of results of FA-CSIA during field studies for tracing of natural food webs. © 2015 Elsevier GmbH.

Аннотация: Sustainability is one of the most important criteria and evaluation of human life support systems intended for use during long space flights. The common feature of biological and physicochemical life support systems is that basically they are both catalytic. But there are two fundamental properties distinguishing biological systems: 1) they are auto-catalytic: their catalysts - enzymes of protein nature - are continuously reproduced when the system functions; 2) the program of every process performed by enzymes and the program of their reproduction are inherent in the biological system itself - in the totality of genomes of the species involved in the functioning of the ecosystem. Actually, one cell with the genome capable of the phenotypic realization is enough for the self-restoration of the function performed by the cells of this species in the ecosystem.

microalgae-bacteria relationships -- photosynthates -- detritus -- Chlorella -- biotic cycle
Аннотация: The paper deals with microalgae-bacteria interrelationships in the "autotroph-heterotroph" aquatic biotic cycle. Explanations of why and how algal-bacterial ecosystems are formed still remain controversial. The paper presents results of experimental and theoretical investigations of the functioning of the algal-bacterial cenosis (the microalga Chlorella vulgaris and concomitant microflora). The Chlorella microbial community is dominated by representatives of the genus Pseudomonas. Experiments with non-sterile batch cultures of Chlorella on Tamiya medium showed that the biomass of microorganisms increases simultaneously with the increase in microalgal biomass. The microflora of Chlorella can grow on organic substances released by photosynthesizing Chlorella. Microorganisms can also use dying Chlorella cells, i.e. form a "producer-reducer" biocycle. To get a better insight into the cenosis-forming role of microalgae, a mathematical model of the "autotroph-heterotroph" aquatic biotic cycle has been constructed, taking into account the utilization of Chlorella photosynthates and dead cells by microorganisms and the contribution of the components to the nitrogen cycle. A theoretical study showed that the biomass of concomitant bacteria grown on glucose and detritus is larger than the biomass of bacteria utilizing only microalgal photosynthates, which agrees well with the experimental data.

Аннотация: The problem of interaction between man and microorganisms in closed habitats is an inextricable part of the whole problem of co-existence between macro- and microorganisms. Concerning the support of human life in closed habitat, we can, conventionally, divide microorganisms, acting in life support system (LSS) into three groups: useful, neutral and harmful. The tasks, for human beings for optimal coexistence with microhabitants seem to be trivial: (1) to increase the activity of useful forms, (2) decrease the activity harmful forms, (3) not allow the neutral forms to become the harmful ones and even to help them to gain useful activity. The task of efficient management and control of microbial population's development in LSS highly depends on mission duration. As for short-term missions without recycling, the proper hygienic procedures are developed. For longer missions, the probability of transformation of the neutral forms into the harmful ones is becoming more dangerous. The LSS for long-term missions are to use cycling-recycling systems, including system with biological recycling. In these systems, microbial populations as regenerative link should be useful and active agents. Some problems of microbial populations control and management are discussed in the paper.

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: 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.

Interaction of a mixed yeast culture in an "autotroph-heterotroph" system with a closed atmosphere cycle and spatially separated components / T. I. Pisman, L. A. Somova // Advances in Space Research. - 2003. - Vol. 31, Is. 7. - P1751-1756, DOI 10.1016/S0273-1177(03)00116-9 . - ISSN 0273-1177

Аннотация: The study considers an experimental model of the "autotroph-heterotroph" system with a closed atmosphere cycle, in which the heterotrophic link is a mixed yeast population. The autotrophic link is represented by the algae Chlorella vulgaris and the heterotrophic link by the yeasts Candida utilis and Candida guilliermondii. The controls are populations of Chlorella and the same yeasts isolated from the atmosphere. It has been shown that the outcome of competition in the heterotrophic link depends on the strategy of the yeast population towards the substrate and oxygen. The C. utilis population quickly utilizes the substrate as it is an r-strategist and is less sensitive to oxygen deficiency. The C. guilliermondii population consumes low concentrations of the substrate because it is a K-strategist, but it is more sensitive to oxygen deficiency. That is why, in the "autotroph-heterotroph" system with a closed gas cycle, after a considerable amount of the substrate has been consumed, the C. guilliermondii population becomes more competitive that the C. utilis population. In the culture of yeasts, isolated from the atmosphere, the C. utilis population finds itself in more favorable conditions due to oxygen deficiency. The system with a complex heterotrophic component survive longer than a system whose heterotrophic component is represented by only one yeast species. This is explained for by the positive metabolite interaction of yeasts and a more complete utilization of the substrate by a mixed culture of yeasts featuring different strategies towards the substrate.

Experimental models of small closed systems with spatially separated unicellular organism-based components. / T. I. Pis'man [et al.] // Life support & biosphere science : international journal of earth space. - 1999. - Vol. 6, Is. 2. - P133-139 . - ISSN 1069-9422

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: 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.
