biodegradation -- fluorophenols -- (19)F NMR -- oxidative defluorination -- Rhodococcus species
Аннотация: Of all NMR observable isotopes (19)F is the one perhaps most convenient for studies on biodegradation of environmental pollutants. The reasons underlying this potential of (19)F NMR are discussed and illustrated on the basis of a study on the biodegradation of fluorophenols by four Rhodococcus strains. The results indicate marked differences between the biodegradation pathways of fluorophenols among the various Rhodococcus species. This holds not only for the level and nature of the fluorinated biodegradation pathway intermediates that accumulate, but also for the regioselectivity of the initial hydroxylation step. Several of the Rhodococcus species contain a phenol hydroxylase that catalyses the oxidative defluorination of ortho-fluorinated di- and trifluorophenols. Furthermore, it is illustrated how the (19)F NMR technique can be used as a tool in the process of identification of an accumulated unknown metabolite, in this case most likely 5-fluoromaleylacetate. Altogether, the (19)F NMR technique proved valid to obtain detailed information on the microbial biodegradation pathways of fluorinated organics, but also to provide information on the specificity of enzymes generally considered unstable and, for this reason, not much studied so far.

Аннотация: The study describes a small closed ecosystem used to test technologies to be further employed in full-scale manned closed ecosystems. The experimental ecosystem is designed to use a certain portion of human metabolism, which is included in the gas, water, and organic waste loops of the system. In this experimental ecosystem, gas and water loops are fully closed, and the model enables processing of human waste and plant inedible biomass. A physicochemical method is used to remove pollutants from the air in the system. A human takes part in the gas exchange of the system through its respiration loop. This experimental ecosystem can be used for testing and improving new technologies to be further used in the future space stations.

Аннотация: The source of radioactive contamination of the Yenisei River floodplain, including contamination with transuranic elements, is the Mining-and-Chemical Combine of the Russian Ministry of Atomic Energy, which has for many years been producing weapons-grade plutonium. Transuranic elements have been detected not only in the soil and sediment of the river but also in the biomass of aquatic plants. This work is an investigation of accumulation and release of 241Am by a submerged macrophyte of the Yenisei River (Elodea canadensis) in laboratory experiments. In 2000-2003, laboratory experiments were carried out with biomass of E. canadensis Mich. and filtered river water. The samples were collected from the Yenisei River upstream of the discharge of the Combine's radioactive effluent. The experiments showed that 241Am is accumulated by Elodea biomass: the activity concentration of 241Am can reach 3280 В± 240 Bq/g, with the concentration factor for 241Am 16 600 В± 2200 l/kg. Results of chemical fractionation have proved that in the course of 241Am accumulation by Elodea biomass, 241Am tightly bound to biomass increases from 11% to 27% of the total 241Am in the biomass. Release of 241Am from the decaying Elodea biomass has been evaluated experimentally. By the end of the experiment (lasting up to 127 days), the Elodea plants had lost up to 65% of their initial 241Am activity and the rate of 241Am release into the water environment reached 23 Bq/day.

Аннотация: The study addresses 242Pu accumulation by Elodea canadensis, one of the abundant species of submerged plants in the Yenisei River. 242Pu in water samples of the "Elodea - Yenisei River water" model system and in the biomass fractions was determined ?-spectrometrically, following radiochemical recovery of 242Pu using 236Pu - a chemical yield tracer. The experiments on accumulation of 242Pu by Elodea biomass showed that the activity concentration of 242Pu can reach 21 В± 2 Bq/g dry wt, with the concentration factor for 242Pu 13100 В± 2100 L/kg dry wt. Results of chemical fractionation proved that during the first few hours of the experiment 242Pu contained in Elodea was mainly concentrated in the exchangeable and the adsorbed fractions of biomass (about 100%). As Elodea biomass accumulated 242Pu, the absolute amount of 242Pu in the exchangeable and the adsorbed fractions remained almost unchanged, although the portion of 242Pu tightly bound to biomass increased. At the end of the experiment, on day 7, 242Pu tightly bound to biomass (fractions of organics and mineral residue) constituted 43-63% (in different experiments) of the total 242Pu in the biomass.

Аннотация: The aim of the paper is to investigate accumulation of artificial radionuclides by the Yenisei river aquatic plants collected in the area affected by the activity of the Mining-and-Chemical Combine (Zheleznogorsk) from 1997 to 2000. The samples of aquatic plants were of four species: Potamogeton lucens, Fontinalis antipyretica, Elodea canadensis, and Ceratophyllum demersum. The gamma-spectrometric analysis of the samples of aquatic plants for artificial radionuclides revealed a wide spectrum of radionuclides. Radionuclides of activation origin were found in the aquatic plants taken both near the Combine and 200 km down of it. The radiochemical analysis of aquatic plants revealed strontium and plutonium isotopes. Among the aquatic plants, the highest concentration factors for the principal radionuclides were recorded in Fontinalis antipyretica (water moss).

Аннотация: The bacterial bioluminescence has high sensitivity to the action of various inhibitors of biological activity. The lyophilized luminous bacteria Photobacterium phosphoreum (Microbiosensor B17 677F) and luminous strain Escherichia coli (Microbiosensor EC) from the Culture Collection IBSO were used to create bioluminescent biotests. They have been applied in ecological monitoring to determine the overall toxicity of the Yenisei and Angara Rivers and some water sources of Altai Territory. As a rule the heaviest pollution of water in studied rivers was registered near cities and settlements. The luminous bacteria biotests are simple and convenient in work, standardized and quantitative, have rapid response to actions of different substances and high sensitivity to environmental pollutants. It takes less than 30 min to do the biotest (the other biotests take 48-96 h). Copyright В© 1999 John Wiley & Sons, Ltd.

Аннотация: A number of approaches have been proposed and tested to transfer enzymatic reactions into the functional elements of microfluidic chips on the example of the bienzyme bioluminescent reaction involving NAD(P)H:FMN-oxidoreductase and luciferase. Measurement of the catalytic activity of these enzymes (under the influence of pollutants) is the basis of enzymatic bioassay of various liquids. It was found that all of the components of the reaction must be placed in the same cell of the chip to improve the reproducibility of the measurements. The use of starch gel as a carrier for immobilization and gelatin as a scaffold in the reactor of the chip enables the preservation of enzyme activity in the course of sealing the chip at room temperature. It is shown that the components of the reaction should be vigorously stirred in a microfluidic chip reactor to improve the efficiency of the analysis. As a result of the studies, a prototype of microfluidic chip based on the enzymatic bioluminescent reaction is proposed. It is characterized by a detection limit of copper sulfate of 3 mu M that corresponds to the sensitivity of traditional lux-biosensors based on living cells. The analysis time is reduced to 1 min, and the analysis can be performed by individuals without special laboratory skills.

Аннотация: This work considers antioxidant properties of natural detoxifying agents-humic substances (HS) in solutions of model inorganic and organic compounds of oxidative nature-complex salt K-3[Fe(CN)(6)] and 1,4-benzoquinone. Bioluminescent system of coupled enzymatic reactions catalyzed by NAD(P) H:FMN-oxidoreductase and bacterial luciferase was used as a bioassay in vitro to monitor toxicity of the oxidizer solutions. Toxicities of general and oxidative types were evaluated using bioluminescent kinetic parameters-bioluminescence intensity and induction period, respectively. Antioxidant activity of HS was attributed to their ability to decrease both general and oxidative toxicities; the HS antioxidant efficiency was characterized with detoxification coefficients D-GT and D-OxT, respectively. Dependencies of D-GT and D-OxT on HS concentration and time of preliminary incubation of the oxidizers with HS were demonstrated. The optimal conditions for detoxification of the oxidizers were >20-min incubation time and 0.5x10(-4) to 2x10(-4) M of HS concentration. The present study promotes application of the enzymatic luminescent bioassay to monitor toxicity of pollutants of oxidative nature in environmental and waste waters in remediation procedures.

Аннотация: The harmful potential of bulk bottom sediments of the Yenisei River has been assessed by the Allium test. Sediment samples have been taken in ten sites on a plot of about 100 km in length in the middle reaches of the Yenisei River affected by urban activity of the city of Krasnoyarsk and industrial plants. The samples of sediments differ considerably in the content of potentially toxic substances (heavy metals, artificial radionuclides, and organic pollutants) and nutrients and in physical properties. We use the mean length of onion root as an indicator of general toxicity, the mitotic index as an indicator of cytotoxicity, and the percentage of anatelophase cells in the apical root meristem with abnormal chromosomes as an indicator of genotoxicity. Both the stimulation and inhibition of indicator endpoints are revealed in sediment samples of the Yenisei River relative to the control (artificial sediments). An increased genotoxicity is recorded in the sample of sediments contaminated by a mixture of organic and chemical toxicants. A significant positive correlation between the percentage of abnormal cells and the content of copper and petrochemicals in the samples is revealed. No extremely strong reactions of onion endpoints to the quality of sediment samples are revealed, which is probably related to relatively low contamination of the sediments studied. This is in agreement with the data of chemical analyses. Based on the testing results, we can conclude that the endpoints of the Allium test are sensitive enough to the quality of bottom sediments of the Yenisei River and can be used for their biotesting.

Аннотация: There is a need for rapid simple and informative environmental assessment methods. The present investigation is aimed at assessing the possibility of using the combined enzyme system of luminescent bacteria: NAD(P)H:FMN-oxidoreductase + luciferase (Red + Luc) for predicting the potential toxicity of industrial urbostratozems sampled in the city of Krasnoyarsk. Three groups of urbostratozems polluted with fluorine, arsenic and lead, were tested by the methods of chemical analysis and enzymatic bioassay. Only the assessment of the arsenic-contaminated soil samples showed the dependence between the reduced activity of the enzyme system and the arsenic concentration variations. The results reveal that the sensitivity of the Red + Luc enzyme system to the soil pollutants depends on the properties of the studied soil samples. Moreover, the solubility of lead in the soil samples affects the accuracy of the enzymatic bioassays for soil toxicity testing. The results of the enzymatic bioassay of the fluoride-contaminated soil samples are ambiguous. The obtained data show the relevance of the sample preparation during integral bioassays. In addition, soil properties should be taken into account as well. The current study emphasizes the importance of conducting chemical and biological testing as a combined set to obtain comprehensive information about the anthropogenic load. (C) 2021 Elsevier B.V.

Аннотация: There is a need for rapid simple and informative environmental assessment methods. The present investigation is aimed at assessing the possibility of using the combined enzyme system of luminescent bacteria: NAD(P)H:FMN-oxidoreductase + luciferase (Red + Luc) for predicting the potential toxicity of industrial urbostratozems sampled in the city of Krasnoyarsk. Three groups of urbostratozems polluted with fluorine, arsenic and lead, were tested by the methods of chemical analysis and enzymatic bioassay. Only the assessment of the arsenic-contaminated soil samples showed the dependence between the reduced activity of the enzyme system and the arsenic concentration variations. The results reveal that the sensitivity of the Red + Luc enzyme system to the soil pollutants depends on the properties of the studied soil samples. Moreover, the solubility of lead in the soil samples affects the accuracy of the enzymatic bioassays for soil toxicity testing. The results of the enzymatic bioassay of the fluoride-contaminated soil samples are ambiguous. The obtained data show the relevance of the sample preparation during integral bioassays. In addition, soil properties should be taken into account as well. The current study emphasizes the importance of conducting chemical and biological testing as a combined set to obtain comprehensive information about the anthropogenic load. © 2021 Elsevier B.V.

Аннотация: The inhibition of bacterial luminescence has been used in testing industrial enterprises sewage. The toxicity of the sewage is less than the total toxicity of separate components due to neutralization of quinone products of polyphenol oxidation in the reactions with the other phenol components of sewage. Toxicity increase is due to their influence on the cell membrane. Studies of cell ultrastructure confirm this fact. The studied mechanism of the complex effect allowed a more accurate forecast of the ecological situation during the discharge of phenol compounds and metals. It also showed the necessity of taking into account the complex effect of sewage components on contaminant discharge into water reservoirs.

Аннотация: The Yenisei River is contaminated with artificial radionuclides released by one of the Russian nuclear plants. The aquatic plants growing in the radioactively contaminated parts of the river contain artificial radionuclides. The aim of the study was to investigate accumulation of artificial radionuclides and stable elements by submerged plants of the Yenisei River and estimate the strength of their binding to plant biomass by using a new sequential extraction scheme. The aquatic plants sampled were: Potamogeton lucens, Fontinalis antipyretica, and Batrachium kauffmanii. Gamma-spectrometric analysis of the samples of aquatic plants has revealed more than 20 radionuclides. We also investigated the chemical fractionation of radionuclides and stable elements in the biomass and rated radionuclides and stable elements based on their distribution in biomass. The greatest number of radionuclides strongly bound to biomass cell structures was found for Potamogeton lucens and the smallest for Batrachium kauffmanii. For Fontinalis antipyretica, the number of distribution patterns that were similar for both radioactive isotopes and their stable counterparts was greater than for the other studied species. The transuranic elements 239Np and 241Am were found in the intracellular fraction of the biomass, and this suggested their active accumulation by the plants. В© 2011 American Chemical Society.

Аннотация: During three field seasons (June-September) of 1997-99 contents of Na, K, Ca, Mg, Fe, Mn, Zn, Cu, Al, Cr, Ni, Cd, and Pb were determined in compartments of ecosystem (surrounding soils, bottom sediments, water, zoobenthos, macrophytes, and fish) of a fish and recreation pond situated at the edge of Krasnoyarsk City (Siberia, Russia). Contents of most parts of metals in soils, water, and macrophytes significantly correlated with each other. As concluded, their contents were determined by natural, general, geochemical peculiarities of the region. Heavy metals, contents of which were higher than federal upper limits of concentration, were revealed. In muscles of fish with different feeding spectra - crucian and perch - concentrations of some metals differed significantly; correlation graphs for metals also had different structures. Comparison of our data with those on diverse aquatic ecosystems of Siberia, Europe, North America, and China published in the last decade was carried out. It was concluded that a distribution of heavy metals in the compartments of an aquatic ecosystem presently have to be determined for each particular water body until general regularities are discovered.

Аннотация: The present study describes detection of potential gaseous pollutants that can produce a toxic effect on plants and humans in the system with wheat plants cultivated on solutions containing liquid products of mineralization of human waste and fish waste. These gaseous pollutants do not inhibit plant growth and development under the experimental conditions, but they may accumulate in closed ecosystems functioning for extended periods of time. Ways to convert gaseous pollutants into environmentally friendly compounds have been proposed. © 2018 Institute of Physics Publishing. All rights reserved.
