     Ostroumov S.A. New scientific disciplines in the system of ecological and biospheric sciences: biochemical ecology and biochemical hydrobiology / / Ecological Chemistry [St.Petersburg]. 2009, 18 (2): p.102-110. Bibliogr. 36 refs. The author has previously published two books in which the conceptual basis of the new scientific discipline of biochemical ecology were formulated. This direction of scientific research is focused on studies of the role of the chemicals produced by organisms in the interorganismal interactions, in communication and regulation of supraorganismal systems. Another part of the science of biochemical ecology deals with the fate and transformation of external chemicals when they interact with organisms. Both natural chemicals and the man-made chemicals are of importance for biochemical ecology. Fundamental concepts of biochemical ecology include ecological chemomediators and ecological chemoregulators, which have been included into the modern scientific concepts and are in use in modern ecological literature (see Rozenberg et al., 1999 ).

The new on phytoremediation potential: acceleration in the decrease in the concentrations of heavy metals (Pb, Cd, Zn, Cu) in water in the presence of elodea./ Ecological Chemistry [St.Petersburg] 2009, 18 (2): p.111-119. Bibliogr. 39 refs. Time-dependent decrease in the concentrations of heavy metals (Pb, Cd, Zn, Cu) in the water of experimental ecosystems (microcosms) with elodea Elodea canadensis was studied. Using the method of inversion voltamperometry, the concentrations of the heavy metals Cd, Zn, Cu, Pb were measured in the water of the experimental microcosms. Aquatic macrophytes Elodea canadensis were incubated in the microcosms. The concentration of Pb, Cd and the other metals decreased markedly. In this experiment, the first convincing evidence was obtained that the measured concentrations of all four heavy metals (Pb, Cd, Zn, Cu) decreased in the microcosms with the macrophytes Elodea canadensis much faster than in the control microcosms without any macrophytes, which proves the new aspect of the phytoremediation potential of elodea.

New experimental data were obtained that showed that one of the most important processes of ecological repairing (restoring water quality during the process of removal of suspended matter by aquatic organisms) is inhibited by a pollutant (a xenobiotic), which points to some degree of similarity or analogy with the processes of repairing at the molecular-genetic level. The repairing at the molecular-genetic level can also be inhibited by some xenobiotics and have some other attributes that are analogous to those of ecological repairing. The xenobiotics that produced those negative effects on the processes of the ecological repairing of water quality included various synthetic surfactants, detergents, and metals. New experimental data on the effects of tetradecyltrimethyl ammonium bromide on marine mussels (Mytilus edulis × M. galloprovincialis) are presented.

Microcosms with the macrophytes were studied in laboratory experiments. The effects of sodium dodecyl sulphate (SDS) on macrophytes were studied . The survival and weight of the biomass of macrophytes in a prolonged incubation were recorded. SDS was added in the form of repeated (recurrent) additions. The increase in the amount of SDS after each addition was: 0,5, 0,8, 1,7, 8,3, 16,7, 50,0 and 100,0 mg in 1 dm3. Duration of survival of plants decreased with increasing amount of SDS in one addition. If the amount of SDS (after a single addition) increased 200 times (from 0.5 to 100 mg / l), the period of survival decreased 53-fold (from 372 up to 7 days). In the presence of SDS, a decrease in macrophyte biomass was observed. The degree of the reduction of biomass depended on the total amount  of SDS added to the microcosms.

Ostroumov, 2009, published in Doklady Akademii Nauk, 2009, Vol. 425, No. 2, pp. 271–272].  The goal of this study was to test whether SDS has an inhibitory effect on the ability of planktonic filter-feeders Daphnia magna to remove phytoplankton from water during their filtration activity. Daphnia were kept under laboratory conditions in vessels and fed with phytoplankton: green algae Scenedesmus quadricauda (Turp.) Breb.). After filtration for 6–24 h in the presence of SDS at concentrations 5 and 10 mg/l, the abundance of S. quadricauda  cells in water was higher than in the control. At the lower SDS concentrations (0.1, 0.5, and 1 mg/l), differences in the abundance of algal cells relative to the control were observed after 3 h of incubation and disappeared after 6–24 h of incubation. The calculation of the mean rate of algae removal by daphnia  showed that this parameter decreased within the first 3 h after the beginning of incubation in the presence of SDS. Thus, the results of our experiments demonstrated that SDS decreases the rate of water filtration by the planktonic crustaceans D. magna.

Lazareva, S.A. Ostroumov, 2009, published in Doklady Akademii Nauk, 2009, Vol. 425, No. 6, pp. 843–845].  Addition of sodium dodecylsulphate (SDS) to water rapidly changed the surface tension of water in the microcosm. The measurements demonstrated that the surface tension of water in the microcosm with the  macrophyte OST1 restored to the level which was close to that of pure water within less than three days. As soon as after 46-h incubation of the system containing the plant phytomass, the surface tension increased significantly and reached that of distilled water. In the variants with water without plant phytomass, restoration of the normal surface tension was much longer (about 17 days). The results demonstrated an accelerated restoration of the normal surface tension which was typical of pure water in those systems that contained SDS in the presence of the phytomass of the  macrophyte OST1. This is consistent with the assumption that the macrophyte accelerates the  disappearance of the surfactant from water.

The level-block approach to the analysis of ecological hazards of anthropogenic effects on the biota (the new conceptualization proposed by the author). On the basis of the previous publications, our new data and the existing scientific literature, we have formulated some fundamental principles that characterize the pivotal roles of the biodiversity of filter-feeders in ecosystems. Among those roles are: (1) the role of ecological repair of water quality (water quality maintenance and improving), (2) the role of contributing to reliability and stability of the functioning of the ecosystem, (3)  the role of contributing to creation of habitat heterogeneity, (4) the role of contributing to acceleration of migration of chemical elements. It is an important feature of the biomachinery of filter-feeders that it removes from water various particles of a very broad range of sizes. Another important principle is that the amount of the organic matter filtered out of water is larger than the amount assimilated so that a significant part of the removed material serves no useful function to the organism of the filter-feeder, but serves a beneficial function to some other species and to the ecosystem as a whole. The new experiments by the author additionally demonstrated  a vulnerability of the filtration activity of filter feeders (e.g. bivalves and  rotifers) to  some   xenobiotics (synthetic surfactant tetradecyltrymethylammonium bromide, heavy metals and some others). The inhibition of the filtration activity of filter-feeders may lead to the situation previously described as that of an ecological bomb of the second type. DOI 10.1007/s10750-004-1875-1.

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 many natural aquatic remediation systems and they can decrease some negative anthropogenic impacts.

Abstracts in Eng. and Italian. [A fundamental concept is proposed of aquatic ecosystem as a bioreactor that carries out the function of water purification in natural water bodies and streams, water quality improvement. The ecosystem as a bioreactor has the following characteristic attributes: (1) it is a large-scale (large-volume) bioreactor; (2) it is a diversified (in terms of the number of taxa and the scope of functional activities) bioreactor; (3) it possesses a broad range of biocatalytic (chemical-transforming and degrading) capabilities. New experimental data on xenobiotics-induced inhibition of the functioning of the molluscs Unio tumidus, U. pictorum, Mytilus galloprovincialis and Lymnaea stagnalis emphasize the potential ecological hazard from sublethal concentrations of pollutants (including those exemplified by synthetic surfactants and detergents)].

Abstracts in Eng. and Italian (p.169). Bibliogr. 21 refs. [=Effetti dell' attività umana sul biota: verso un nuovo sistema di principi e criteri per l'analisi dei rischi ecologici. [The currently accepted system of criteria for evaluating environmental and ecological hazards of man-made chemicals (pollutants) is vulnerable to criticism. In this paper, a new concept of the system of approaches towards criteria for evaluating the ecological hazard from man-made impact is proposed. It is suggested to assess the man-made impacts (including effects of pollutants and xenobiotics) on the biota according to the following four levels of disturbance in biological and ecological systems: (1) the level of individual responses; (2) the level of aggregated responses of groups of organisms; (3) the level of stability and integrity of the ecosystem; (4) the level of contributions of the ecosystem to biospheric processes. On the basis of the author’s experimental studies, an example is given of how to apply the proposed approach and the system of criteria to the analysis of concrete experimental data. To exemplify the efficiency of the proposed approach, it is shown how to use it to analyze new data on effects of a synthetic surfactant on water filtering by bivalves. It is concluded that the proposed approach will be helpful in better assessing environmental and ecological hazards from anthropogenic effects on biota, including effects of man-made chemicals polluting ecosystems.

The role of filter-feeders as factors of water purification in ecosystems is so important that their inhibition is a danger for the entire ecosystem. The author emphasizes that not only the biodiversity of filter-feeders but also their level of functional (filtration) activity is to be protected. In order to do so, we suggest establishing a new type of protected areas whose main purpose is to protect functionally active populations of filter-feeders, including bivalves and other organisms. Those protected areas could be named hydrobiological (some variants: biofiltering, or malacological) reserves (some variants: refuges, sanctuaries, etc.)]. In Russ., translated into English:

It is especially important for aquatic ecosystems, water quality maintenance and improving.  Phytoplankton grazers contribute to the top-down control of phytoplankton populations. The paper is focused on the role of benthic filter feeders in the control of plankton populations as a result of water filtering and the removal of cells of plankton from the water column. New data on the inhibitory effects of surfactants and detergents on benthic filter-feeders (freshwater mussels Unio tumidus, U. pictorum, marine mussels Mytilus galloprovincialis, M. edulis, and oysters Crassostrea gigas) are presented and discussed. Importance and efficiency of that approach to the problems of eutrophication and water self-purification is pointed out.

[New data on the inhibition of filter-feeders by chemical mixtures (detergents) are reported. The detergent Lanza-Automat (20 mg/L) inhibited water filtration by the bivalves (oysters) Crassostrea gigas (incubation time 4-35 min, 23.4ºC).

[In 1935, the term 'ecosystem' was coined by A. Tansley. In the 1940s, another important term  'biogeocoenosis' was introduced by V. N. Sukachev. Since that time, a significant amount of new facts was accumulated in ecology. It is necessary to revisit the formulation of the basic concepts and terms in ecology, including the two terms mentioned above. The author proposed some new variants of the definition of the two terms that (1) reflect the modern vision of the basics of ecology; and (2) avoid the vicious circle of using other terms which  in turn request their definitions. 5 specific features of the proposed definition of ecosystem (Table 1). 8 specific features of the proposed definition of biogeocenosis, and 8 distinctions between the proposed definition and the classical definition by V.N.Sukachev (Table 2)].

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 concentration was measured every 30 min for an hour and a half. The inhibiting effect on the mollusk filtration rate (FR) was qualitatively described. After the first 30 min filtration at 4 mg/l initial SDS concentration, the cell density was 322% of the control. The inhibiting effect was observed later as well. Due to FR inhibition in the vessels with the above specified initial SDS concentration, the algae cell density was 6.4 and 14.7 times that of the control after 1 and 1.5 h, respectively. Thus, SDS can decrease the natural capacity of aquatic ecosystems for self-purification and disturb other aspects of ecosystem functioning through inhibiting the filtration activity of mussels.

Univ. (Biol.). [=Bulletin of Moscow University. Ser. Biology]. 1997. No. 3, pp. 30-36. Effects of sodium dodecyl sulphate (SDS) on the filtering rate of the mussels were studied. Anionic surfactant SDS (1, 2 and 4mg/L) inhibited water filtration by bivalves Mytilus edulis and removal from water of cells of algae Isochrysis galbana; the incubation time was 30-90 min (Tables 1 and 2). Aliquats of the alga Isochrysis galbana suspension were added to the beakers with mussels and sea water, and the filtering activity was measured by counting the algal cells at 30 min intervals during 1.5 h. After the first 30 min period, the cell density was 135% of that in the control at the initial SDS concentration 1 mg/L and 198% at 2 mg/L. A still greater difference in the algal cell concentration between the experiment and the control was observed when the SDS concentration was increased to 4 mg/L: it was 3 times higher after the first 30 min period, 6 times higher after 60 min and more than 14 times higher after 90 min. It is inferred that by inhibiting the filtering activity of the mussels SDS may reduce the natural self-purification capacity of aquatic ecosystems. The list of parameters of the ecosystem that may be changed under the effect of synthetic surfactants is given in Table 3. The experimental findings are discussed in the context of environmental protection and water quality improving with reference to literature data.

Reconstitution of Biological Molecular generators of electric current. Bacteriorhodopsin. - J. Biol. Chem., 1976 Vol. 251, Issue 22, 7059-7065. [1. Photoinduced generation of electric current by bacteriorhodopsin, incorporated into the planar phospholipid membrane, has been directly measured with conventional electrometer techniques. 2. Two methods for bacteriorhodopsin incorporation have been developed: (a) formation of planar membrane from a mixture of decane solution of phospholipids and of the fraction of violet fragments of the Halobacterium halobium membrane (bacteriorhodopsin sheets), and (b) adhesion of bacteriorhodopsin-containing reconstituted spherical membranes (proteoliposomes) to the planar membrane in the presence of Ca2+ or some other cations. In both cases, illumination was found to induce electric current generation directed across the planar membrane, an effect which was measured by macroelectrodes immersed into electrolyte solutions on both sides of the membrane. 3. The maximal values of the transmembrane electric potential were of about 150 mV at a current of about 10(-11) A. The electromotive force measured by means of counterbalancing the photoeffect by an external battery, was found to reach the value of 300 mV. 4. The action spectrum of the photoeffect coincides with the bacteriorhodopsin absorption spectrum (maximum about 570 nm). 5. Both components of the electrochemical potential of H+ ions (electric potential and delta pH) across the planar membrane affect the bacteriorhodopsin photoelectric response in a fashion which could be expected if bacteriorhodopsin were a light-dependent electrogenic proton pump. 6. La3+ ions were shown to inhibit operation of those bacteriorhodopsin which pump out H+ ions from the La3+-containing compartment. 7. The photoeffect, mediated by proteoliposomes associated with thick planar membrane, is decreased by gramicidin A at concentrations which do not influence the planar membrane resistance in the light. On the contrary, a protonophorous uncoupler, trichlorocarbonylcyanidephenylhydrazone, decreases the photoeffect only if it is added at a concentration lowering the light resistance. The dark resistance is shown to be higher than the light one, and decreases to the light level by gramicidin. 8. A simple equivalent electric scheme consistent with the above results has been proposed].
