- Vibrio cholerae is the infectious agent of the deadly diarrheal disease, cholera. Na+ ion homeostasis is believed to play a key role in both physiology and pathogenicity of this bacterium. However, molecular mechanisms of sodium exchange in V. cholerae are still poorly understood. In the present work a gene encoding an unusual Na+/H+ antiporter, nhaD, was identified in the ...Journal: Molecular and Cellular Biochemistry - MOL CELL BIOCHEM , vol. 229, no. 1, pp. 119-124, 2002
- Effects of several surfactants and chemical mixtures on marine bivalves were studied. An anionic surfactant, sodium dodecylsulphate (SDS), and a cationic surfactant, tetradecyltrimethylammonium bromide (TDTMA), inhibited the filtering activity of oysters (Crassostrea gigas). Similar effects were exhibited by some chemical mixtures that included surfactants. Those mixtures inhibited the filtering activity of Crassostrea gigas and Mytilus galloprovincialis. The new results are ...
- Effects of three surfactants on the filtration rates by marine mussels were studied. The xenobiotics tested represented anionic, cationic and non-ionic surfactants (tetradecyltrimethylammonium bromide, a representative of a class of cationic surfactants; sodium dodecyl sulphate, a representative of anionic alkyl sulfates; and Triton X-100, a representative of non-ionic hydroxyethylated alkyl phenols). All three surfactants inhibited the clearance ...

- V.I. Vernadsky pointed out that “the living matter in the biosphere plays a fundamental and active role, and in exercising its power it is in no way comparable with anything else, with any other geological factor.” [1]. Finding concrete evidence that support this statement still remains an important aspect in the study of ecosystems, including aquatic systems. To ...
- A new contribution to the scientific basis of phytoremediation and phytotechnology for water treatment. It is the first paper that reports the experiment in which it was proved that the aquatic plants helped remove a synthetic surfactant from water. ** It was discovered that plant biomass help towards restoration the water quality in the system which was polluted with a synthetic ...
- Suspension-feeders are found in both pelagic and benthic systems. They function as an important part of an ecosystem's biomachinery that maintains water quality in aquatic systems. They remove suspended matter and excrete faeces, pseudofaeces and dissolved inorganic materials that contribute to nutrient cycling between the water column and the benthic habitats. Suspension-feeders are a key part of ...

KolesnichenkoThe search for proteins with immunochemical affinity to plant stress proteins in endemic Baikal fishes shows the presence of proteins, immunochemically related to plant heat-stabile proteins and plant uncoupling protein CSP 310. Western blotting showed that among the native cytoplasmic proteins of endemic Baikal fishes there are proteins immunochemically related to heat-stabile plant proteins with molecular weights about ...
- Principles of the theory of the ecological mechanism of water self-purification based on multiple functions of the biota in freshwater and marine ecosystems are formulated. In developing this theory, the results of the author's experiments with filtering hydrobionts have been used. These results indicate that the water self-purification mechanism is vulnerable to the impact of some pollutants ...

- Earlier, the author published two books and some papers, in which he described conceptual foundations of new scientific disciplines — biochemical ecology and biochemical hydrobiology. These trends in research include studies of the role of chemical substances in interorganismal interactions, in communication and regulation of supraorganismal systems. Another part of biochemical ecology concerns studies of the destiny and transformation of external ...
- Many species of planktonic and benthic invertebrates are active filter-feeders. The filtration activity of aquatic organisms is of great importance for the functioning of ecosystems [1‐3]. It was shown earlier that surfactant sodium dodecylsulfate (SDS) inhibits the filtration activity of Mytilus edulis, M. galloprovincialis , and some other aquatic filter-feeders [4‐15], which is manifested in a decreased removal of ...
- The effects of the anionic surfactant sodium dodecyl suplphate on the aquatic macrophyte Potamogeton crispus L. are studied. Concentrations of 83–133 mg/l caused fragmentation of the stems of plants. The tolerance of the plants to the negative effects of the surfactant was higher in the spring (April) than in the autumn (September).

Biodetritus that formed over a 7-month period in microcosms with Viviparus viviparus, Unio pictorum, and Ceratophyllum demersum contained a number of elements. This is the first study to determine concentrations of some elements in biodetritus. Neutron activation analysis showed that the elements’ concentrations decrease in the following order: Ca > Zn > Ba > Br > Ce > Se &...

The effect of synthetic anionic surface active substance (SAS) sodium dodecylsulfate (SDS, 4 mg/l) on the kinetics of water filtration by mussel Mytilus edulis was studied. A suspension of algae Isochrysis galbana was added to the vessel with the mussels, and their filtration activity was measured by counting the concentration of the algae cells in the experimental vessels. Algae ...

All aspects of regulatory interactions between organisms are of significant importance for ecosystem structure and functions. Certain aspects of regulatory interactions were considered in the preceding works [1, 2]. Regulatory interactions in trophic chains, including the regulation of lower links by higher links (the top‐ down control), are of cardinal importance [3, 4]. The ecosystem regulation disturbances caused by anthropogenic ...
