Аннотация: Using mathematical modeling methods, the work investigates possible existence of a phytoflagellate population in the ecosystem of a stratified lake (Lake Shira, Khakasia, Russia). Until this study was carried out, no phytoflagellate population had been detected in the lake, although there had been indirect evidence of the possible presence of a cryptomonad population in this water body. To answer the question if this population may be present in this water body, as the first step of investigation, a mathematical model was developed describing the microorganism biomass dynamics and phytoflagellate relationship with the lake food web. The calculations showed that cryptophytic algae were abundant in the water column layers above the lake chemocline at the beginning of summer but showed low biomass concentrations during other periods of time. In the summer following the construction of the model, samples were collected from Lake Shira, as the next step of the study. A cryptophytic algae population was found in the water column, and the pattern of its distribution in the ecosystem was similar to that predicted by the model. In addition to that, we studied theoretically possible reasons for the early summer development of the population in the deep water layers and found that it was the result of the mixotrophic feeding strategy of cryptomonads and trophic interactions in the food web. The study shows that preliminary modeling of the locational and temporal distribution of populations whose presence in the ecosystem is only suggested by indirect evidence may be useful as a tool for searching for the species in natural ecosystems and as an approach enabling a more accurate description of the food web structure of a water body.

Аннотация: Studies were conducted to investigate the antibiotic resistance of freshwater, halophile and moderate halotolerant bacteria isolated from the nearshore part of Shira lake, which is affected by the activity of a health resort, and from the central part of the lake in the summer (June to August) of 1999. It has been shown that the allochthonous microflora, which is brought into the lake with the resort effluent in mid-summer, is the anthropogenic factor contributing to an increase in the number of freshwater bacteria that feature multiple antibiotic resistance in the central part of the lake. It has been found that resistance to ampicillin of freshwater and halophile heterotrophic bacteria is related to the increase in the biomass of blue-green and green algae in the central part of Shira lake between mid-July and the end of August. A mathematical model has been constructed to describe the dynamics of the antibiotic resistance of heterotrophic bacteria in the close-to-resort and the central parts of Shira lake under natural and anthropogenic impacts.

Аннотация: The work analyzes functioning of a "producer-consumer" closed aquatic system with spatially separated links, where each component consisted of two species. Producers in the system were the microalgae of Chlorella vulgaris and Scenedesmus sp., consumers - Paramecium caudatum infusoria and Brachionus sp. rotifers. In the experiment the competing predators were consuming on a mixed culture of algae, and the competition of algae was studied under nitrogen limitation. Under these conditions competitiveness of Scenedesmus was higher than that of Chlorella vulgaris. Metabolism products of Scenedesmus algae have been found to have negative effect on reproduction of Paramecium caudatum protozoa. Predator population dynamics in the "consumer" link demonstrated that the rotifers that consume two algal species are more competitive compared to protozoa feeding on chlorella only. (C) 2001 COSPAR.

Interaction of a mixed yeast culture in an "autotroph-heterotroph" system with a closed atmosphere cycle and spatially separated components [Text] / T. I. Pisman, L. A. Somova ; ed.

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.

Аннотация: The use of relative variable fluorescence (RVF) of chlorophyll, as measured in the presence of Diuron, an inhibitor of electron transfer, for the estimation of the photosynthetic activity of plankton microalgae was analyzed under a wide range of light intensities in the PAR region. Oxygen evolution rates (estimated by the method of light and dark bottles and the amperometric method), RVF, and chlorophyll a concentration were measured in parallel in natural algal cenoses and microecosystems. When the previously used regression equation, in the form A = b(DeltaF/F-d)CchlI, where A is O-2 evolution rate (g/(m(3) h), DeltaF/F-d is RVF (relative units), C-chl is chlorophyll a concentration (mg/m(3)), and I is light intensity (W/m(2)), was verified in the PAR region, we observed a nonlinear dependence of the correction coefficient b on I, which can be described by the formula b = 6.227 x 10(3)rootI. This result agrees with the hypothesis that chlorophyll a fluorescence quenching comprises photochemical (qQ) and energy (qE) components. On the basis of the energy model, we determined the upper limit b(max) = 0.003 for light intensity range I < 4.4 W/m(2) and the lower limit b(min) = 0.0003 for I = 400 W/m(2).

Аннотация: One of the key problems of long-term space missions is limited service life of units. The only exceptions are biological components of biological Life Support Systems - higher plants or microorganisms. These components are capable of self-restoration: after complete disintegration, they can appear again from seeds or spores. The estimate of failure intensity of BLSS regeneration component includes: a number of self-sustained sections of the regeneration component; permissible boost (how many times can productivity of a component be increased); time required to repair (restore) a component; the crew existence time, when all LSS regeneration components fail; failure rate of one section of a regeneration component. Evaluations show that for hydrogen-oxidizing bacteria and micro-algae very high reliability is achieved even for one or two sections. In the case of higher plants (due to low rate of self-restoration) bio-regenerative module has to be divided into 10 self-sustained sections operating simultaneously. These measures can decrease the probability of catastrophe by a factor of 10 (C) 1999 COSPAR. Published by Elsevier Science Ltd.

Аннотация: An experimental investigation was carried out, and a mathematical model of interaction between invertebrates (infusoria Paramecium caudatum and rotifera Brachionus plicatilis) and algae (Chlorella vulgaris and S enedesmus quadricauda) in the <> aquatic biotic cycle with spatially divided links was constructed. The model describes the dynamics of a mixed culture of infusoria and rotifera in the <> link, when they consume a mixed culture of algae coming from the <> link. A negative influence of products of algae Scenedesmus metabolism upon the reproduction of infusoria P. caudatum was revealed. Taking this into account, a qualitative coincidence of the results of mathematical modeling with experimental data was obtained. It was shown that the co-existence of mixed algae culture in the <> link with invertebrates in the <> link in the <> aquatic biotic cycle is impossible because of the displacement of infusoria P. caudatum by rotifera Brachionus plicatilis.

Аннотация: The paper presents a experimental and mathematical model of interactions between invertebrates (the ciliates Paramecium caudatum and the rotifers Brachionus plicatilis) in the "producer-consumer" aquatic biotic cycle with spatially separated components. The model describes the dynamics of the mixed culture of ciliates and rotifers ill the "consumer" component, feeding on the mixed algal culture of the "producer" component. It has been found that metabolites of the algae Seenedesmus produce an adverse effect on the reproduction of the ciliates P. caudatum. Taking into account this effect, the results of investigation of the mathematical model were in qualitative agreement with the experimental results. In the "producer-consumer" biotic cycle it was shown that coexistence is impossible ill the mixed culture of invertebrates of the "consumer" component. The ciliates P. caudatum are driven out by the rotifers B. plicatilis. (C) 2009 Published by Elsevier Ltd on behalf of COSPAR.

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

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.
