Biosorption of copper by biomass of extremophilic algae.
Russian Journal of General Chemistry (2015-12-01) 85: 2961-2964 , December 01, 2015 By Ostroumov, S. A.; Shestakova, T. V.; Tropin, I. V. ; Copper and lead are among the most important chemical pollutants of the environment including hydrosphere. Interaction of these heavy metals with biomass of aquatic plant organisms including algae is an area of active research in ecological chemistry. We investigated the interaction of the biomass of unique extremophilic (thermophilic) algae Galdieria sulphuraria with these heavy metals in aquatic environment using stripping voltammetry. Biosorption of copper by the studied biomass from aquatic medium has been discovered; however, no biosorption of another heavy metal from aquatic environment with the biomass has been detected. The experiments with the mortmass of Galdieria sulphuraria have revealed no sorption of the heavy metals as measured by stripping voltammetry. The difference in the interaction of copper and lead with the algal biomass is important for deeper understanding of the biosorption phenomenon. The new data stimulated further interest to the concept of biogenic migration of chemical elements that was proposed by V.I. Vernadskii. The results contributed to the scientific basis for innovative biotechnology to decontaminate water.

Toxicity testing of chemicals without use of animals.
Russian Journal of General Chemistry (2016-12-01) 86: 2933-2941 , December 01, 2016 By Ostroumov, S. A. ;
A series of publications on the studies of phytotoxicity of chemicals (pollutants, ecotoxicants), carried out by the author and his research group, have been reviewed. Tests (bioassays) based on experiments with many higher plant species, both terrestrial and aquatic ones (macrophytes), were used in these studies. Among the chemicals tested there were various organic (synthetic detergents, surfactants, and pesticides) and some inorganic (e.g., metal oxide nanoparticles) compounds. New methods for bioassay using plant species never used before have been developed by the author. New facts of phytotoxicity of a synthetic detergent have been discovered and reported. Specifically, an aqueous solution of liquid detergent Frosch (Werner & Mertz, FRG) at a concentration of 0.25 mL/L (and higher concentrations) inhibited the elongation rate of seedlings of Lens culinaris higher plant species.

Also, phytotoxicity of synthetic cationic surfactant dodecyltrimethylammonium bromide has been reported for the first time. This surfactant at a concentration of 4 mg/L inhibited the elongation of Lens culinaris plant seedlings. The phytotesting methods contribute to the development of alternative approaches to studying the toxicity of chemicals through non-animal testing.

New Aspects of the Role of Organisms and Detritus in the Detoxification System of the Biosphere.
Russian Journal of General Chemistry (2017-12-01) 87: 3190-3198 , December 01, 2017 By Ostroumov, S. A. ; The review covers new aspects of the participation of organisms in the detoxification system of the biosphere. Problems of detoxification of toxic environmental pollutants are analyzed. New author’s experimental data in combination with a large amount of information in the scientific literature gave rise to a new concept of the role of biogenic detritus and related nutrients in environmental detoxification (ex-living matter concept). This may be useful for the development of new technologies for remediation and decontamination of the environment.

Water Quality and Conditioning in Natural Ecosystems: Biomachinery Theory of Self-Purification of Water.
Russian Journal of General Chemistry (2017-12-01) 87: 3199-3204 , December 01, 2017 By Ostroumov, S. A. ; General principles of the theory of polyfunctional role of biota in self-purification of water in aquatic ecosystems have been formulated. The theory includes the following elements: (1) energy sources for self-purification of aquatic ecosystems; (2) main functional units of the self-purification system; (3) main selfpurification processes; (4) contributions of major taxa to self-purification of aquatic ecosystems; (5) reliability of the system and mechanisms ensuring it; (6) self-regulation of biota; (7) response of the system to external stimuli (impacts); (8) analogy between an ecosystem and a bioreactor; (9) conclusions for nature conservation practice. The theory covers both freshwater and marine ecosystems.

Biocontrol of water quality: Multifunctional role of biota in water self-purification. Russian Journal of General Chemistry (2010-12-01) 80: 2754-2761 , December 01, 2010 By Ostroumov, S. A. ; 6+ Citations; The experimental data analysis, concepts, and generalizations in this article provide the fundamental elements of the qualitative theory of biocontrol of water quality in a systematized form. The theory covers water self-purification in freshwater and marine ecosystems. The theory is supported by the results of the author’s experimental studies of the effects exerted by some chemical pollutants including synthetic surfactants, detergents, and other xenobiotics onaquatic organisms. The theory provides a basis for remediation of polluted aquatic ecosystems including purification of water bodies and streams, and briefly present the qualitative theory of the self-purification mechanism of aquatic ecosystems, phytoremediation and other types of technologies.

Issues of the Study of Detritus in Aquatic Systems.
Russian Journal of General Chemistry (2017-12-01) 87: 3244-3249 , December 01, 2017 By Sadchikov, A. P.; Ostroumov, S. A. ; In this paper, we present the analysis of the ecological roles of detritus and suspended particulate matter in aquatic ecosystems. New data that have been obtained for freshwater ecosystems of the central part of Russian Federation (Moscow Region, e.g., Mozhaiskoe Reservoir) have been included in the analysis. These new data include the results of studies of samples of water and detritus from the aquatic ecosystems. The review analysis addresses both freshwater and marine ecosystems. The multifunctional important role of detritus in aquatic ecosystems has been shown and exemplified using data for aquatic bodies of different trophic level, from oligotrophic to eutrophic.

Phytotoxicity of a surfactant-containing product towards macrophytes. Russian Journal of General Chemistry (2013-12-01) 83: 2614-2617 , December 01, 2013 By Ostroumov, S. A.; Solomonova, E. A. ; 3+ Citations. Extending the studies of surfactant-containing products, we have investigated the effect of the Liquid Crystal Concentrate detergent on aquatic macrophytes Elodea canadensis within laboratory microcosms. It has been shown that the detergent produced some negative influence on the macrophytes at 50–150 μL/mL (5–15 vol %).

(Uranium, Palladium, Ruthenium, Selenium, Cerium, Zirconium, Indium),
by biogenic materials derived from an aquatic macrophyte was explored. The concentrations of scandium and some other chemical elements were measured in the dried biomass (mortmass) of aquatic plants Myriophyllum aquaticum. In the experiments, the mortmass was incubated in aquatic systems where some chemical elements were added to the aquatic medium. After the incubation, the concentrations of these chemical elements in the mortmass were measured using inductively coupled plasma atomic emission spectroscopy (ICP-AES), also referred to as inductively coupled plasma optical emission spectrometry (ICP-OES). Increases in the concentrations of scandium and some other chemical elements (Ce, In, Se, Ru, Pd, U, and Zr) were observed in the biogenic material. https://www.researchgate.net/publication/292950214;
