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: Dynamics of catalase activity has been shown to reflect the growth curve of microorganisms in batch cultivation (celluloselythic bacteria Bacillus acidocaldarius and bacteria of the associated microflora Chlorella vulgaris). Gas and substrate closure of the three component ecosystems with spatially separated components "producer-consumer-reducer" (Chl. vulgaris-Paramecium caudatum-B. acidocaldarius, two bacterial strains isolated from the associated microflora Chl. vulgaris) demonstrated that the functioning of the reducer component can be estimated by the catalase activity of microorganisms of this component.

Аннотация: The dynamics of accumulation of polyhydroxybutyrate (PHB) and the activities of the key enzymes of PHB metabolism (beta-ketothiolase, acetoacetyl-CoA reductase, PHA synthase, D-hydroxybutyrate dehydrogenase, and PHA depolymerase) in the hydrogen bacterium Ralstonia eutropha B5786 were studied under various conditions of carbon nutrition and substrate availability. The highest activities of beta-ketothiolase, acetoacetyl-CoA reductase, and PHA synthase were recorded at the stage of acceleration of PHB synthesis. The activities of enzymes catalyzing PHB depolymerization (PHB depolymerase and D-hydroxybutyrate dehydrogenase) were low, being expressed only at stimulated endogenous PHB degradation. The change of carbon source (CO2 or fructose) did not cause any marked changes in the time course of enzyme activity.

Заглавие : On monitoring the bacterial component as an indicator of the state of small man-made ecosystems

Аннотация: High reproduction rates make the bacterial component of ecosystems a good indicator of the state of the system on the whole. This determines the necessity to develop rapid monitoring of the functional state of the bacterial component of small ecosystems. Information about substrate concentration in the population is indicative of the state of the bacterial culture. Conventional methods of monitoring the concentration of integral substrate in the system take time much longer than the changes in the ecosystem. The paper presents theoretical foundations for the logical sequence "catalase activity - intracellular substrate concentration - estimate of substrate consumed by bacteria" for experimental verification and as a consequence of development of the integral method of monitoring the bacterial population on the basis of determining bacterial catalase activity.

Аннотация: We describe our experience with laboratory courses in enzymology based on the phenomenon of bioluminescence. The soluble and immobilized enzymes of luminous bacteria are used and the practical enzymological course consists of four main courses: (1) training in measuring the activities of soluble and immobilized enzymes; (2) the investigation of kinetic characteristics (kinetic constants) and enzyme-substrate and enzyme-inhibitor interactions in the bacterial bioluminescent reaction; (3) The testing of physico-chemical characteristics of enzymes (pH, temperature, ion strength, etc.); (4) the effect of inhibitors on enzymes. Training is possible in groups of about ten persons. Our practice work has been introduced in the biological, pedagogical and physical departments of Krasnoyarsk State University. Students of the pedagogical department have created a popular and interesting series of laboratory works for high school children aged 14-17 years. Copyright (C) 1999 John Wiley & Sons, Ltd.

Заглавие : Untangling metabolic and spatial interactions of stress tolerance in plants. 1. Patterns of carbon metabolism within leaves
Место публикации : Protoplasma. - 2010. - Vol. 245, Is. 1. - С. 49-73. - ISSN 0033183X (ISSN) , DOI 10.1007/s00709-010-0135-7

Аннотация: The localization of the key photoreductive and oxidative processes and some stress-protective reactions within leaves of mesophytic C3 plants were investigated. The role of light in determining the profile of Rubisco, glutamate oxaloacetate transaminase, catalase, fumarase, and cytochrome-c-oxidase across spinach leaves was examined by exposing leaves to illumination on either the adaxial or abaxial leaf surfaces. Oxygen evolution in fresh paradermal leaf sections and CO2 gas exchange in whole leaves under adaxial or abaxial illumination was also examined. The results showed that the palisade mesophyll is responsible for the midday depression of photosynthesis in spinach leaves. The photosynthetic apparatus was more sensitive to the light environment than the respiratory apparatus. Additionally, examination of the paradermal leaf sections by optical microscopy allowed us to describe two new types of parenchyma in spinach-pirum mesophyll and pillow spongy mesophyll. A hypothesis that oxaloacetate may protect the upper leaf tissue from the destructive influence of active oxygen is presented. The application of mathematical modeling shows that the pattern of enzymatic distribution across leaves abides by the principle of maximal ecological utility. Light regulation of carbon metabolism across leaves is discussed. В© 2010 Springer-Verlag.
