Abstract:
A 12-day incubation experiment with the addition of glucose to soils contaminated with persistent organic pollutants (POPs) was carried out in order to estimate the potential microbial activities and the potential of the soil microbial biomass C to degrade 1,1,1-trichloro-2,2-bis(p-chlorophenyl) ethane (DDT), polychlorinated biphenyls (PCB) and polycyclic aromatic hydrocarbons (PAHs). The microbial activities were affected in different ways depending on the type of pollutant. The soil organic matter also played an important role. The microbial activities were affected particularly by high concentrations of PAHs in the soils. Soil microorganisms in the PAHs contaminated soil used the added glucose to a lesser extent than in the non-contaminated soil, which in the contaminated soil resulted in a higher microbial biomass content during the first day of incubation. DDT, DDD and DDE, and PCB affected the soil microbial activities differently and, in comparison with control soils, decreased the microbial biomass C during the incubation. The increased microbial activities led to a significant decrease of PAH up to 44.6% in the soil long-term contaminated with PAHs, and up to 14% in the control soil after 12 days of incubation. No decrease of PAHs concentrations was observed in the soil which was previously amended with sewage sludges containing PAHs and had more organic matter from the sewage sludges. DDT and its derivates DDD and DDE decreased by about 10%, whereas the PCB contents were not affected at all by microbial activities. Studies on the microbial degradation of POPs could be useful for the development of methods focused on the remediation of the contaminated sites. An increase of soil microbial activities caused by addition of organic substrates can contribute to the degradation of pollutants in some soils. However, in situ biodegradation may be limited because of a complex set of environmental conditions, particularly of the soil organic matter. The degradability and availability of POPs for the soil microorganisms has to be estimated individually for each contaminated site.

Abstract:
Oil pollution can cause tremendous harm and risk to the water ecosystem and organisms due to the relatively recalcitrant hydrocarbon compounds. The current chemical method used to treat the ecosystem polluted with diesel is incompetent and expensive for a large-scale treatment. Thus, bioremediation technique seems urgent and requires more attention to solve the existing environmental problems. Biological agents, including microorganisms, carry out the biodegradation process where organic pollutants are mineralized into water, carbon dioxide, and less toxic compounds. Hydrocarbon-degrading bacteria are ubiquitous in the nature and often exploited for their specialty to bioremediate the oil-polluted area. The capability of these bacteria to utilize hydrocarbon compounds as a carbon source is the main reason behind their species exploitation. Recently, microbial remediation by halophilic bacteria has received many positive feedbacks as an efficient pollutant degrader. These halophilic bacteria are also considered as suitable candidates for bioremediation in hypersaline environments. However, only a few microbial species have been isolated with limited available information on the biodegradation of organic pollutants by halophilic bacteria. The fundamental aspect for successful bioremediation includes selecting appropriate microbes with a high capability of pollutant degradation. Therefore, high salinity bacteria are remarkable microbes for diesel degradation. This paper provides an updated overview of diesel hydrocarbon degradation, the effects of oil spills on the environment and living organisms, and the potential role of high salinity bacteria to decontaminate the organic pollutants in the water environment.

Abstract:
Biodegradation of pollutants in the environment is directly affected by microbial communities and pollutant mixture at the site. Lab experiments using bacterial consortia and substrate mixtures are required to increase our understanding of these processes in the environment. One of the deficiencies of working with environmental cultures is the inability to culture and identify the active strains while knowing they are representative of the original environment. In the present study, we tested the aerobic microbial degradation of two brominated flame retardants, tribromo-neopentyl alcohol (TBNPA) and dibromo neopentyl glycol (DBNPG), by an assembled bacterial consortium of four strains. The four strains were isolated and plate-cultured from a consortium enriched from the impacted groundwater underlying the Neot Hovav industrial area (Negev, Israel), in which TBNPA and DBNPG are abundant pollutants. Total degradation (3–7 days) occurred only when the four-strain consortium was incubated together (25 °C; pH −7.2) with an additional carbon source, as both compounds were not utilized as such. Bacterial growth was found to be the limiting factor. A dual carbon–bromine isotope analysis was used to corroborate the claim that the isolated strains were responsible for the degradation in the original enriched consortium, thus ensuring that the isolated four-strain microbial consortium is representative of the actual environmental enrichment.

Abstract:
Presently water pollution is the one of the major threats faced by living things all over the world. The main cause of water pollution is its effect on the life of aquatic animals. Organic, inorganic, microbial and other pollutants often mix with water bodies mainly due to human activities. Because of the presence of pollutants in water, the amount of dissolved oxygen level can be decreased which in turn affect the survival of aquatic life. The pollutant water may enter the agriculture fields and damage the plants extensively. The methods, such as, coagulation, adsorption, foam floating, electrodialysis, capacitive deionization, etc. are presently employed to treat the waste water. Among these methods, heterogeneous photocatalytic degradation is considered to be a good method because of its low cost and environmental friendliness. In this review, the decontamination of different kinds of organic, inorganic and microbial contaminants in water with different photocatalysts process is presented.

Abstract:
Dehalogenases are microbial enzyme catalysed the cleavage of carbon-halogen bond of halogenated organic compounds. It has potential use in the area of biotechnology such as bioremediation and chemical industry. Halogenated organic compounds can be found in a considerable amount in the environment due to utilization in agriculture and industry, such as pesticides and herbicides. The presence of halogenated compound in the environment have been implicated on the health and natural ecosystem. Microbial dehalogenation is a significant method to tackle this problem. This review intends to briefly describe the microbial dehalogenases in relation to the environment where they are isolated. The basic information about dehalogenases in relation to dehalogenation mechanisms, classification, sources and the transportation of these pollutants into bacterial cytoplasm will be described. We also summarised readily available synthetic halogenated organic compound in the environment.

Abstract:
Under the influence of epidemic situation, the treatment of pollutants is stricter. After the epidemic, how to treat the river pollutants by microorganisms has become a difficult problem. In this paper, the microbial treatment technology of water pollution was studied, and the water quality model was used to simulate the process of microbial degradation of river pollutants. The dynamic equation is used to describe the relationship among microbial proliferation, removal of organic pollutants, change of dissolved oxygen concentration, different forms of nitrogen and different forms of phosphorus, so as to realize the mathematical expression of water quality change in the process of microbial treatment of river pollutants. Finally, the numerical simulation model of microbial treatment of river pollution is obtained through experimental analysis, which provides an accurate reference model for the prevention and control of river pollution after the outbreak.

Abstract:
Hazardous organic and metallic residues or by-products can enter into plants, soils, and sediments from processes associated with domestic, municipal, agricultural, industrial, and military activities. Handling, ingestion, application to land or other distributions of the contaminated materials into the environment might render harm to humans, livestock, wildlife, crops, or native plants. Considerable remediation of the hazardous wastes or contaminated plants, soils, and sediments can be accomplished by composting. High microbial diversity and activity during composting, due to the abundance of substrates in feedstocks, promotes degradation of xenobiotic organic compounds, such as pesticides, polycyclic aromatic hydrocarbons (PAHs), and polychlorinated biphenyls (PCBs). For composting of contaminated soils, noncontaminated organic matter should be cocomposted with the soils. Metallic pollutants are not degraded during composting but may be converted into organic combinations that have less bioavailability than mineral combinations of the metals. Degradation of organic contaminants in soils is facilitated by addition of composted or raw organic matter, thereby increasing the substrate levels for cometabolism of the contaminants. Similar to the composting of soils in vessels or piles, the on-site addition of organic matter to soils (sheet composting) accelerates degradation of organic pollutants and binds metallic pollutants. Recalcitrant materials, such as organochlorines, may not undergo degradation in composts or in soils, and the effects of forming organic complexes with metallic pollutants may be nonpermanent or short lived. The general conclusion is, however, that composting degrades or binds pollutants to innocuous levels or into innocuous compounds in the finished product.

Abstract:
Over the past decade, many studies have been done on the semiconductor photominieralization of water pollutants. There is still an apparent lack of knowledge or further calcification required concerning details of the photocatalytic degradation mechanism, and factors associated with the reaction. The aim of this thesis is to address various fundamental aspects of semiconductor photocatalysis. Thus in Chapter three, the often used concept that O2 is a necessary reactant in the semiconductor photocatalysis of organic pollutants is challenged in a detailed study of the kinetics of photomineralisation of 4-chlorophenol and acetone, sensitised by TiO2 using metal ions, such as Fe3+, Cu2+ and Hg2+, rather than, and in addition to, O2, as the electron acceptors. Chapter four highlights the poorly understood world of semiconductor photocatalysis kinetics and mechanisms with a study of the effect of light intensity upon the apparent Langmuir-Hinshelwood constants found for the photomineralisation of 4-chlorphenol, sensitised by Degussa P25 powder dispersions. Chapter five describes the results of a detailed study of the kinetics of photomineralisation of 4-CP, sensitised by a film of Degussa P25 - the first example of such a study. The similarities and differences in kinetics of photomineralisation of the dye methylene blue sensitised by TiO2 are explored. This dye features widely in semiconductor photocatalysis as test organic pollutant and is used to evaluate the activities of different photocatalysts. However, the kinetics and underlying mechanisms for photobleaching are much more complex than previously recognised, as revealed by the results of this study.

Abstract:
A polyphasic approach was used to examine the impact of contamination on soil microbial community structure. Two systems were examined using a combined biochemical and molecular biological approach. Petroleum hydrocarbon contaminated soils from two Northern Canadian sites, representing long-term contamination, were examined using Biolog GN plates and PCR-denaturing gradient gel electrophoresis (DGGE) analysis of total community 16S rDNA. Results obtained using both methods demonstrated a positive correlation between samples that was based on the geographical origin of the samples, not on contamination level. In the second system, non-contaminated soil was contaminated with the explosive hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) to monitor the effect of short- to medium-term contamination. Changes in the soil microbial community were examined using PCR-DGGE of total community 16S rDNA combined with RDX mineralization and chemical analysis of intermediates. The non-contaminated loam soil had an inherent RDX degradative capability and contamination of soil columns with 1000 mg RDX/kg soil did not significantly change the 16S rDNA bacterial community profile. The bacterial diversity remained high as estimated by the number of bands present in the DGGE and by NQ-78704 statistical rarefaction analysis of 16S rDNA clone RFLPs. The same soil, used in 10% soil slurries (w/v), demonstrated two apparently different RDX degradation mechanisms based on mineralization and chemical analysis. The differences were based on aerobic versus anaerobic conditions and the presence/absence of Na3 citrate. PCR-DGGE performed on 16S rDNA from aerobic slurries amended with Na3-citrate detected the stimulation of 3 operational taxonomic units, identified as Stenotrophomonas sp., Sphingomonas sp. and a member of the Alcaligenaceae. The results from the two systems examined (short- to medium-term and long-term contamination) demonstrated the utility of a polyphasic approach in the examina

Abstract:
Increasing amounts of organic synthetic chemicals are currently emitted to the environment by human activities. The more recalcitrant fraction of this pollutant mixture reaches marine ecosystems mainly through rivers, continental run-off, and diffuse atmospheric inputs. Once in seawater, it represents the anthropogenic fraction of the dissolved organic carbon (ADOC) pool. However, the total amount of ADOC is unknown, while its effects to ecosystems and detailed composition is largely unknown. Over the past decades, the scientific research effort has focused on the effects of organic pollutants (OPs) in marine biota, especially in oil spills events or under toxicological testing in laboratories, neglecting the importance of the chronic pollution perturbation of the biosphere composition caused by diffusive inputs of large number of pollutants at low concentrations. Our aim was to combine functional genomic tools with quantitative biogeochemical approaches under manipulated conditions to determine the bidirectional interaction between marine microbial community structure and function and the ADOC present in coastal seawater. Additionally, it was also intended to perform similar experiments in areas with diverse environmental conditions to elucidate the role of the trophic conditions and levels of pollutants in the response. In order to fulfil the proposed objectives, several OP amendment experiments were performed with different OP additions and contrasted seawater from the North-Western Mediterranean, the Arctic and the Antarctic. On the one hand, the effect caused by 4 families of pollutants individually (alkanes, polycyclic aromatic hydrocarbons, organophosphate esters and perfluoroalkyl substances (PFAS)) was tested in 5 marine bacterial communities of the NW Mediterranean, and the specific effect of perfluorooctanesulfonate (PFOS) and perfluorooctanoate acids (corresponding to the family of PFAS) in communities from Deception Island (Antarctica). On the other hand, experiments were conducted to observe the effect of an operationally defined ADOC, which consisted of the non-polar extract of seawater, to bacterial communities from coastal waters with very different starting environmental conditions (Livingston Island (Antarctica), Svalbard (Arctic), Barcelona and Blanes (Mediterranean)). The results suggest that the baseline ADOC pollution ubiquitously present in the oceans, two orders of magnitude lower than DOC, is modifying bacterial communities and its functionality. ADOC induced the growth of rare taxa, most of them known as pollutants degraders, but also modified the activity of some metabolic pathways from certain taxonomical groups, such as those related to hydrocarbon breakdown and PFOS desulfurization. Consequently, this work provided evidences that ADOC might be changing the dynamics of ocean biogeochemical cycles. The relevance of this perturbation will need to be constrained with future research. At the same time, marine microorganisms are adapted to modulate the concentration and state of incoming pollutants, as an example, we have observed a PFOS decrease in incubations with bacteria from Antarctic waters. However, the bidirectional interaction between ADOC and marine bacteria is closely related with environmental variables and conditions (nutrients availability, water temperature, etc.), as well previous exposure to pollutants probably facilitating an adaptation of the communities. In terms of the pool of ADOC, the same ADOC perturbation did not result in the same response for marine communities in the Mediterranean, Arctic and Antarctica. The suite of microbial responses are thus taxa and compound specific and besides the growth of the rare biosphere, range from degradation of pollutants, changes in the enzymatic activities, modification of the composition of the cell membranes and surface properties, compound specific stress responses, among others.
En la actualidad, se emiten cantidades cada vez mayores de productos químicos sintéticos orgánicos al medio ambiente. La fracción más recalcitrante de esta mezcla llega a los ecosistemas marinos principalmente a través de ríos, escorrentía continental y por la entrada difusiva atmosférica. Una vez en el agua de mar, ésta representa la fracción antropogénica de la reserva de carbono orgánico disuelto (ADOC). Sin embargo, la cantidad total de ADOC, su composición específica y sus efectos en los ecosistemas son en gran parte desconocidos. En las últimas décadas, el esfuerzo de investigación científica se ha centrado en los efectos de los contaminantes orgánicos (CO) en la biota marina, especialmente en eventos de derrames de petróleo o mediante pruebas toxicológicas en laboratorio, descuidando la importancia de la contaminación crónica y ubicua causada por la entrada atmosférica. Nuestro objetivo era determinar la interacción bidireccional entre la estructura y función de la comunidad microbiana marina y el ADOC presente en el agua de mar. A su vez, también se quería dilucidar el papel de las condiciones tróficas y los niveles de contaminantes iniciales en la posterior respuesta. Para cumplir con los objetivos, se realizaron varios experimentos de adición de CO a diferente concentración y composición, así como en varias aguas de mar del Mediterráneo, Ártico y Antártida. Por un lado, se probó el efecto causado por 4 familias de contaminantes de manera individual (alcanos, hidrocarburos aromáticos policíclicos, ésteres de organofosfato y sustancias perfluoroalquílicas) en 5 comunidades del Mediterráneo. També se examinó el efecto específico de los ácidos perfluorooctanosulfonato (PFOS) y perfluorooctanoato en la Isla Decepción (Antártida). Por otro lado, se realizaron experimentos para observar el efecto del ADOC, que consistía en el extracto no-polar de agua de mar, en las comunidades bacterianas con condiciones ambientales iniciales muy diferentes (Isla Livingston (Antártida), Svalbard (Ártico), Barcelona y Blanes (Mediterráneo). Los resultados sugieren que la contaminación de ADOC, presente de manera ubicua en los océanos y dos órdenes de magnitud más baja que el DOC (Dissolved Organic Carbon), está modificando las comunidades bacterianas y su funcionalidad. En los experimentos realizados, el ADOC indujo el crecimiento de especies microbianas raras, la mayoría de ellas conocidas como degradadoras de contaminantes, pero también modificó la actividad de rutas metabólicas de ciertos grupos taxonómicos, como los relacionados con la degradación de hidrocarburos y la desulfuración de PFOS. En consecuencia, este trabajo ha proporcionado evidencias sólidas de que el ADOC debe de estar cambiando la dinámica de los ciclos biogeoquímicos oceánicos. Al mismo tiempo, los microorganismos marinos están adaptados para modular la concentración y el estado de los contaminantes entrantes. Como ejemplo, hemos observado una disminución a lo largo del tiempo de la concentración de PFOS en las incubaciones con bacterias marinas antárticas. Sin embargo, la interacción bidireccional entre ADOC y microorganimos está estrechamente relacionada con las variables y condiciones ambientales (disponibilidad de nutrientes, temperatura del agua, etc.), así como la exposición previa a los contaminantes, probablemente facilitando una mejor adaptación de las comunidades. En términos del ADOC, la misma perturbación con ADOC no resultó en la misma respuesta para las comunidades marinas en el Mediterráneo, el Ártico y la Antártida. El conjunto de respuestas microbianas es, por lo tanto, específico de cada taxón y CO. Dicha respuesta puede verse reflejada en el crecimiento de la biosfera rara, la biodegradación de los contaminantes, los cambios en las actividades enzimáticas, la modificación de la composición de las membranas celulares y sus propiedades de superficie, o una respuesta de estrés específica al compuertso, entre otras (...)

Abstract:
Bioremediation holds the promise as a cost effective treatment technology for a wide variety of hazardous pollutants. In this study, the biodegradation of organic compounds discharged together with radioactive wastes is investigated. Nuclear process wastewater was simulated by a mixture of phenol and strontium, which is a major radionuclide found in radioactive wastewater. Phenol was used in the study as a model compound due to its simplicity of molecular structure. Moreover, the biodegradation pathway of phenol is well known. Biodegradation studies were conducted using pure cultures of Pseudomonas aeruginosa and Pseudomonas putida. The rate of phenol degradation by both species was found to be higher in the test without strontium. This suggests some degree of inhibition in the degradation of phenol by strontium. There was no phenol degradation in the sterile controls. The results indicate the feasibility of the biodegradation of organic pollutants discharged in radioactive effluents by specialised microbial cultures.

Abstract:
Nonylphenol (NP) is the most abundant environmental estrogen listed as one of the priority hazardous substances in the Water Framework Directive (EC 2000) and the priority pollutant of Baltic Sea (HELCOM 2010). The present study aims to compare the effects of technical nonylphenol (tNP) on the cellulase, amylase and protease activity of the terrestrial fungal strains played a significant role in aquatic ecosystems due to their high adaptive capacity and a large range of functional activity. The study also attempts to understand the mechanisms behind the varying sensitivity of the terrestrial fungi to tNP. The fungal strains were isolated from the bottom sediments of the coastal area of the eastern part of the Gulf of Finland. The terrestrial fungi were identified based on their morphological characteristics and nucleotide sequence analysis of internal transcribed space region. One reason for significant differences in sensitivity to the toxicant studied among the fungi is the change in the fungal cell permeability, in particular in cell membrane permeability, induced by NP. Environmentally relevant concentrations of tNP cause significant changes in activity of hydrolytic enzymes in the terrestrial fungi Aspergillus tubingensis, Penicillium expansum, Penicillium glabrum, and Cadophora fastigiata involved in organic matter degradation in bottom sediments. There can be increasing or decreasing trend, depending on both the type of enzyme and the tNP concentration. The revealed changes may disrupt the destructive processes in bottom sediments, as well as succession and stability of microbial communities functioning in the aquatic environment. It was found that tNP contributes to the activation of proteolytic enzymes, considered as potential fungal virulence factors. This may lead to emergence fungal strains with enhanced virulence in aquatic microbiocenoses. The investigations of the physiological responses of terrestrial fungi under nonylphenol will be important for biochemical processes dynamics and their environmental consequences evaluation.

Abstract:
In tanneries, environmental problems have special implications in terms of optimizing the consumption of used chemicals, applied technologies, the degree of recovery of useful substances from leather waste. Biodegradation is the process by which organic substances are broken down by microorganisms. From an ecological point of view, biodegradability assessments of new materials and compounds in the industry are essential to understand and quantify their impact on the environment. The sustainable development of the leather industry has focused on major environmental issues, such as clean production methods and waste management. Tanneries generate huge quantities of solid wastes as pelt waste. If these bio-waste materials are not utilized properly, they are potential source of pollution. Microbiological degradation of pelt waste is amongst the permanent concerns of leather processing units. The process may have the purpose of decomposing waste to exploit by-products as biocompost or to obtain proteases through a biotechnological process. These enzymes can be used after purification in various processes that have animal protein as a substrate. They can also be used in raw state for enzymatic hydrolysis. The paper aims at development of an experimental model on the bioenzymatic degradation process of protein waste from tanneries.
