Opis:
Produkty ropopochodne stanowią złożoną mieszaninę związków o zróżnicowanych własnościach biologicznych, które mogą być przyczyną niekorzystnych dla człowieka i organizmów żywych zmian zachodzących w skażonych ekosystemach. W wyniku prowadzonych prac bioremediacyjnych (obejmujących bioremediację stymulowaną substancjami biogennymi oraz inokulację biopreparatami z mikroorganizmów autochtonicznych) mogą powstawać metabolity o zróżnicowanej i słabo poznanej aktywności biologicznej. Niektóre z nich mogą być bardziej toksyczne niż substrat wyjściowy i posiadać własności mutogenne lub rakotwórcze. Ocenę skuteczności stosowanych zabiegów remediacyjnych na dołach urobkowych uzupełniono o monitoring toksykologiczny prowadzony przy użyciu organizmów żywych jako biowskaźników reprezentujących wszystkie poziomy troficzne (producentów, konsumentów i reducentów) danego ekosystemu, co pozwala na kompleksową ocenę stanu badanego środowiska. Celem badań było określenie wpływu zanieczyszczeń ropopochodnych oraz pośrednich metabolitów powstających w procesach bioremediacyjnych na biocenozę glebową na podstawie przeprowadzonych biologicznych testów toksyczności, fitotoksyczności i genotoksyczności. W badaniach zastosowano opracowane i produkowane przez firmę Microbiotest z Belgii testy biologiczne: Phytotoxkit, Ostracodtoxkit, testy toksyczności ostrej Microtox Solid Phase oraz testy mutagenności Amesa. Uzyskane wyniki badań pozwalają na prześledzenie zmian własności toksycznych w trakcie prowadzenia procesów oczyszczania gleby z dołów urobkowych oraz na stwierdzenie przydatności rekultywowanych terenów do użytkowania rolniczego i leśnego.
Petroleum products are complex mixture of compounds of varied biological properties. They can cause harmful changes in contaminated ecosystems and threaten humans and living organisms as well. Bioremediation (including bioremediation stimulated with biogenic substances and inoculation with biopreparations from autochthonous microorganisms) can result in creation of metabolites with a varied structure and biological activeness, which has been partly recognised. Some of them are more toxic than an initial substrate. Besides, they have mutagenic features and are responsible for cancer. Estimation of effectiveness of remediation in waste pits was completed with toxicological monitoring. It was led with the use of living organisms as biomarkers representing all trophic levels of a chosen ecosystem: producers, consumers and reducers. This process enables total estimation of natural environment condition. The aim of the research was to determine influence of petroleum contaminants and indirect metabolites (in bioremediation processes) on soil biocenose. The results of biological tests (toxicity, phytotoxicity and genotoxity) have been taken into account. The following biological tests, prepared and produced by Microbiotest (a Belgian company), were applied: Phytotoxkit, Ostracodtoxkit, acute toxicity tests Microtox Solid Phase and Ames mutagenity tests. The obtained results enable observation of changes in toxic properties during purification of soil taken from waste pits. In addition, it can be claimed if the areas are suitable for agricultural and forest usage.

Biosurfactants

environment
Opis:
Biosurfactants are surface-active molecules produced by variety of microorganisms like bacteria, yeasts or fungi. They consist of both hydrophilic (polar head) and hydrophobic (non-polar chain) moiety. Such structure allows them to reduce interfacial tension or create microemulsions. Biosurfactants can be produced as a part of cell membrane or extracellular compounds. They show foaming, wetting, emulsifying and dispersing properties. Biosurfactants are characterized by low toxicity, high biodegradability and they do not accumulate in living organisms. Biosurfactants are mostly used in environmental clean-up technologies. However due to many properties biosurfactants find use in various industries, such as: petroleum, pharmaceutical, textile or cosmetic. Microbial surface active compounds can improve the degradation of hydrocarbons from soil and water. Besides they are capable of degrading polycyclic aromatic hydrocarbons (PAHs). Biosurfactants help removing heavy metals like lead, cadmium or zinc, from soil. Rhamnolipids synthesized by bacteria of the Pseudomonas aeruginosa are the most commonly used biosurfactants in the remediation process. The aim of this paper is to present different applications of biosurfactants in environmental remediation based on literature review. The paper is based on literature studies.

Opis:
The plants of three species (Zea mays L., Panicum miliaceum L. and Panicum maximum Jacq.) were grown on the soil contaminated with 0.3 mM CsCl solution traced with 137Cs, in the greenhouse. For all the species, the fresh-to-dry weight ratio was equal in the caesium-treated plants and in the control group after 3 weeks of culture. The shoot-to-root fresh weight and dry weight ratios were decreased in maize, unchanged in Panicum miliaceum and increased in Panicum maximum, comparing to the control without caesium treatment. The shoot/soil and also root/soil transfer factors (TF) for 137Cs (measured by means of NaI gamma spectrometer) were always the highest in maize, then lower in Panicum miliaceum and the lowest in Panicum maximum. All the plants seem to be hyperaccumulators of caesium. The root/soil TF was especially high in maize, i.e. 55 (kBq kg 1 biomass)/(kBq kg 1 soil). The shoot/root concentration factor (CF) for 137Cs was the lowest in maize, higher in Panicum miliaceum and the highest in Panicum maximum. The hyperaccumulation of 137Cs in the whole plant was the highest in maize, lower in Panicum miliaceum and the lowest in Panicum maximum. The proved ability of the investigated plants for phytoextraction of the soil caesium points to the possibility to utilise these plants in the soil bioremediation. From this point of view, Panicum maximum seems to be the most useful plant because it accumulates caesium mainly in the shoot, and maize would be the least useful species since it has the highest accumulation in the root.

Using microorganisms in eliminating or reducing the impacts of harmful remnants is very ancient manner. The current study was conducted to explore the potential of utilizing some fungi species that isolated from the main sewage treatment plant in Al-Muamirah area, Babylon-Iraq, in reducing some pollutants. Six fungi taxa Aspergillus flavus, A. niger, A. terrues, Candida albicans, C. krusei, and Penicillium digitatum were identified before any treatment process, whereas only four fungi species A. flavus 20%, A. niger 20%, A. terrues 10%, and P. digitatum 18% were recognized after completing the physical and chemical treatment stages. Only three taxa A. niger, A. terrues, and P. digitatum were employed to reveal their capability in treating the sewage water, which represent the biological treatment stage as the final step of the treatment processes. The results showed a considerable capability of these fungi species in decreasing many variables values such as pH, total soluble solids (TSS), electrical conductivity (EC), salinity, total alkalinity, chlorides, nitrite, and phosphate. Where, slightly low reduction was detected in TSS value in all experiments (1.1–5.9%), similarly, both EC and salinity which were decreased with low ratios (6.6%, 3.9%, respectively). Taxon A. terrues exhibited high ability in reducing the total alkalinity and chloride ions in the treated water (30.9%, 43%, respectively) in comparison with the other two fungi species. Furthermore, all three fungi species were posed high capability in decreasing nutrients, where both nitrite and phosphate ions were highly reduced (87–97% and 22.8–32.1%, respectively). Based on these findings, we suggest using other microorganisms and exploring their capacity in removing the pollutants, and revealing the ability of the above fungi taxa in removing other pollutants.

In this work, the nutrients and eutrophication problem are integrated into a nature-based solution by incorporating microalgae-based nutrient removal from wastewater and collecting the residue in an anaerobic digestion plant to produce biogas that is directly exported to an existing gas-fired power plant and closes the bioresource loop. El Burullus lake in Egypt was selected as a case study because it is rich in nutrients and suitable for the integrated system. The theoretical results were promising as for one-hectare, nutrient pollution could be reduced with a total nitrogen removal rate of 4 kg•d-1, a total phosphorus removal rate of 1.1 kg•d-1, and a total COD removal rate of 9.3 kg•d-1. The digester volume corresponding to the biomass produced was 120 m3 per hectare of algae pond and the methane yield () from anaerobic digestion was 73 m3•d-1.

Opis:
Salinization and sodification of agricultural lands in arid and semi-arid regions of the world are two limiting factors in the crop production. This study was conducted to evaluate the effect of readily available agricultural residues on changing some chemical properties of saline-sodic soils. Wheat, potato, sunflower, and canola residues were separately added into three saline-sodic soils at a rate of 2% by weight and thoroughly mixed with soils. Control and treated soils were incubated for 168 days at a constant moisture and temperature. The pH, electrical conductivity (EC), soluble cations, available nitrate (NO3-) and phosphorous (P), cation exchange capacity (CEC), and exchangeable sodium percentage (ESP) were measured during the incubation. The EC increased in the response to the incorporation of plant residues, whereas the pH was reduced. The application of organic components in soils increased CEC and decreased ESP. The results showed that the maximum reduction in ESP was observed in the potato treatment because of the highest Ca2+ concentration. The average reduction in ESP of treated soil samples at the end of incubation followed this order: 16.1% (potato residue-treated soil) >12.7% (canola residue-treated soil) >11.1% (wheat residue-treated soil) >9.6% (sunflwer residue-treated soil). The potato residue was the most effective amendment in changing the chemical properties of saline-sodic soils in comparison with other organic residues. The results indicated that the application of organic residues had a positive impact on reducing the soil sodicity and improving the soil fertility depending on their chemical composition.

Opis:
Effects of heavy metals on plants result in growth inhibition, structure damage, a decline of physiological and biochemical activities as well as of the function of plants. The effects and bioavailability of heavy metals depend on many factors, such as environmental conditions, pH, and species of element, organic substances of the media and fertilization, plant species. But, there are also studies on plant resistance mechanisms to protect plants against the toxic effects of heavy metals. The microorganisms act in synergism with the plants for effective phytoremediation. This synergistic relationship promotes the exchange of water and nutrients established between plant roots and specialized soil microorganisms thus, enhancing the plant growth. The application of microorganisms in phytoremediation helps to improve plant growth and survival rate. The microbial activity in the contaminated site acts as an indicator for the plant growth and bioremediation. So an attempt were made on the toxic effects of chromium in paddy plants growth and yield and thereby mitigating its toxicity by using microbial inoculants especially Azospirillum.

Opis:
The current investigation is the first report of utilization of Aspergillus brasiliensis for the decolorization of melanoidin in distillery effluent. The effluent generated from alcohol distilleries is one of the most complex wastewater with a high biological oxygen demand (BOD) and other organic, inorganic, and toxic constituents. The effluent contains melanoidin, a dark brown compound, which is difficult to remediate by using conventional technologies. The disposal of spent wash in the natural environment is hazardous and can deteriorate land and water resources. The decolorization of spent wash through physical and chemical methods remains unsuitable, and the only alternative to decolorize spent wash is biological treatment. In the current study, three fungal strains were isolated from the distillery waste and screened for their ability to decolorize melanoidin.The isolate RS2 exhibited maximum decolorization of 83% and was identified as Aspergillus brasiliensis. Its optimum growth temperature was 37EC, and the maximum efficiency was recorded after 120 h of incubation. Nutritional sources were investigated for the fungi showing the maximum decolorization of melanoidin, and starch and peptone were found to be the best carbon and nitrogen sources, respectively. At 1.5% starch concentration and 1.5% peptone concentration, the decolorization level attained was 87.45% and 88.74%, respectively. A. brasiliensis exhibited a high potential to decolorize melanoidin. The decolorization percentage was high, which makes this fungus a potential candidate for use at the industrial scale for the bioremediation of spent wash.

The aluminium contaminated soil is currently being a concern due to the use of aluminium waste as a material for building roads and river dams in Jombang District, Jawa Timur Province, Indonesia. This application was debated because aluminium waste is categorized as hazardous waste. One widely known method for treating the metal contaminated soil is bioremediation. One potential indigenous bacterial species to remove aluminium, Vibrio alginolyticus was isolated from contaminated soil. A toxicity test to V. alginolyticus showed that this bacterium could grow in aluminium contaminated soil until 100 mg/L equal to 48 mg/kg concentration. The removal of aluminium from soil was conducted by using 50 and 100 mg/L concentration. The result showed that the addition of 2% v/v of V. alginolyticus can remove 5.48% aluminium from 100mg/L contaminated soil initial concentration after 12 days of test period. The addition of V. alginolyticus did not significantly influence the removal of aluminium from contaminated soil (p>0.05).

The objective of this research project was to evaluate the implementation of a phytoremediation system for the effluents generated by the National Cancer Institute (INCAN), Central Department, Paraguay to contribute to the management of the liquid waste that it generates. The system consisted of a set of three pools, in which were made up of floating Typha domingensis Pers plants, at an approximate density of 10 plants per m2, all the roots formed a filter, which was in direct contact with the effluent. The effluent was of continuous flow; the flows of entry and exit were regulated according to the generation of liquid waste by INCAN. There were 5 measurements made with an interval of 7 days for each measurement, at a point of entry and exit of the effluent, to determine the system. The parameters evaluated were: BOD5, COD, NTK, PT, pH, temperature, conductivity, turbidity, dissolved oxygen and fecal coliforms. The results showed a considerable reduction of the pollutants generated for all the parameters evaluated, obtaining an efficiency of 67.9 to 92.4% in the evaluated parameters, indicating that it is very feasible to implement this type of systems for phytodepuration of liquid waste.

Opis:
The autotrophic forms of microalgae are referred to as "efficient biological factories", because they play a significant role in CO2 removal from the atmosphere by utilizing it for the process of photosynthesis. The industrial application of microalgae biomass includes the production of cosmetics, health products, fertilisers, biofuel, feeds, and food. Microalgae biomass is also an important tool used in the treatment of wastewater. The current review is aimed at reviewing the progress and prospects of microalgae resource modelling and optimisation as a tool for sustainable biotechnology. The mechanism of biomass production by microalgae tends to vary according to whether the microalgae are autotrophic, heterotrophic, or mixotrophic organisms. In the current study, the modelling and optimisation of microalgae biomass production were discussed, as well as the modelling of CO2 sequestration, light intensity, nutrients, and photobioreactor. The role of microalgal biomass production in attaining sustainable biotechnology has also been extensively studied. Microalgae are an emerging tool used in the phycoremediation of wastewater and reduction of high CO2 level. The modelling and optimisation of microalgae biomass production will help to upscale the production of the microalgal based fuel and bioproducts from model scale to the money-making level.

Opis:
This study was conducted to investigate the degree of bioremediation that would occur in the samples of soil polluted with raw and treated crude petroleum (oil) with the aid of Aspergillus niger (fungi) and Pseudomonas aeruginosa (bacteria). This was achieved by monitoring the Organic carbon content in the soil over 45 days and pH over 25 days. Four systems of 500 g soil were polluted with 40 g treated crude petroleum, while four systems were contaminated with 40 g raw crude petroleum. The eight systems were labeled accordingly. Two systems for raw crude control and treated crude control (RCC and TCC) were left as control, two systems for raw crude Aspergillus niger and treated crude Aspergillus niger (RCA and TCA) were treated with Aspergillus niger only, two systems for raw crude Pseudomonas aeruginosa and treated crude Pseudomonas aeruginosa (RCP and TCP) were treated with Pseudomonas aeruginosa only and the last two systems for raw crude Aspergillus niger and Pseudomonas aeruginosa (RCAP and TCAP) were treated with both Pseudomonas aeruginosa and Aspergillus niger. At the end of the bioremediation period, the results obtained showed that the pH was not particularly a solid parameter to estimate the degree of bioremediation. This is because a proper trend in the results obtained could not be determined. Additionally, it was observed that Aspergillus niger (fungi) and Pseudomonas aeruginosa (bacteria) alone and separate remediate raw crude polluted soil better than treated crude polluted soil. This was determined by the TOC (Total Organic Carbon) values on the 45th day of the experiment.
