Available in PDF, EPUB and Kindle. Book excerpt: The soil is being contaminated continuously by a large number of pollutants. Among them, heavy metals are an exclusive group of toxicants because they are stable and difficult to disseminate into non-toxic forms. The ever-increasing concentrations of such pollutants in the soil are considered serious threats toward everyone's health and the environment. Many techniques are used to clean, eliminate, obliterate or sequester these hazardous pollutants from the soil. However, these techniques can be costly, labor intensive, and often disquieting. Phytoremediation is a simple, cost effective, environmental friendly and fast-emerging new technology for eliminating toxic heavy metals and other related soil pollutants. Soil Remediation and Plants provides a common platform for biologists, agricultural engineers, environmental scientists, and chemists, working with a common aim of finding sustainable solutions to various environmental issues. The book provides an overview of ecosystem approaches and phytotechnologies and their cumulative significance in relation to solving various environmental problems. - Identifies the molecular mechanisms through which plants are able to remediate pollutants from the soil - Examines the challenges and possibilities towards the various phytoremediation candidates - Includes the latest research and ongoing progress in phytoremediation

Download or read book Bioremediation of Petroleum Hydrocarbons in Cold Regions written by Dennis M. Filler and published by Cambridge University Press. This book was released on 2008-02-21 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide to bioremediation in cold regions is designed to aid environmental practitioners, industry, and regulators in the remediation of petroleum spills and contaminated sites in cold regions. Remediation design and technology used in temperate climates does not necessarily work in cold climates, and cleanup takes longer due to shorter treatment seasons, sub-freezing temperatures, ground freezing and thawing, and limited bioactivity. Environmental engineers and scientists from eight countries working in the polar regions combine their experiences and expertise with petroleum contamination to write this book. It contains in-depth discussions on regulations, freezing and frozen ground, identification and adaptations of cold-tolerant bacteria, contaminant transport in cold soils and permafrost, temperature effects on biodegradation, analytical methods, treatability studies, and nutritional requirements for bioremediation. Emphasis is given to practical and effective bioremediation methods for application in cold regions. Emerging technologies are also discussed.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract Discovery of New Oil-Degrading Bacteria with Biosurfactant Production Ability from Oily Tailings Pond Waste, Refinery-Contaminated Soil, Light and Heavy Crude Oils for Remediation of Crude Oil in Water Mohammad Rahimi, M.A.Sc. Concordia University, 2019 Contamination of water and soil with crude oil and petroleum compounds frequently occurs. Removal of oil contamination is often not economically feasible by traditional remediation techniques. Therefore, the development of effective, fast, and bio-based remediation methods that can lessen the damaging effects of oil contamination and lower treatment costs are of great importance. Numerous oil-degrading bacteria with biosurfactant production ability have been isolated from oil-related environments. However, less attention has been given to the application of these compounds in the oil-related activities. The objectives of this study were to discover potential oil-degrading bacteria with biosurfactant (BS) production ability with potential application for crude oil bioremediation from oily tailings pond waste, refinery-contaminated soil, light and heavy crude oils by using the enrichment culture technique. The biodegradation tests were conducted in Erlenmeyer flasks containing water (350 mL, pH 7, salinity of 30 ppt) amended with nutrients and crude oil as the only carbon source (2 mL). The contribution of discovered oil-degrading bacteria in the crude oil biodegradation was determined at different periods of biodegradation by analysis of the remaining of total petroleum hydrocarbons using a gas chromatograph (GC-FID). Moreover, the production and properties of produced biosurfactants were assessed through surface tension (ST) and oil-displacement tests. A total of five oil-degrading bacteria species were discovered from oily tailings pond waste (1 species), refinery-contaminated soil (two species), light crude oil (one species) and heavy crude oil (one species). All species showed biosurfactant production ability. The lowest surface tensions of supernatants at the end of the biodegradation period were between 55 mN/m to 40 mN/m. The minimum ST belonged to the BS produced by species discovered from oily tailings pond waste (40 mN/m). Moreover, an average crude oil biodegradation of 70% was obtained with the isolated bacteria from samples following five weeks of incubation. This study confirmed the fast and effective biodegradation of crude oil by the isolated bacteria with the biosurfactant production as the main mechanism of oil uptake.

Download or read book Study on Biodegradation of Miri and Masila Crude Oil and Used Car Oil by Microorganisms Isolated from Malaysian Soil and the Effect of Aeration and NKP Addition on Biodegradation Process written by Khairi Ali Alennabi and published by . This book was released on 2012 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, five contaminated soil samples with benzene, used car oil and diesel were collected from five car workshops in Kuala Lumpur area, Malaysia. The microbial strains were isolated using selective media (agar containing crude oil, used car oil and benzene). Microorganisms were identified by biochemical test and then used in biodegradation experiment of two types of crude oils (Miri and Masila) and used car oil. Qualitative determination of the degradation capacity of crude oils and used car oil was driven in 24 well cell culture cluster - flat bottom, adding to each well nutrient broth medium, crude oil or used car oil and the isolated microorganism cultured in the tubes (single and mixtures) and incubated at 27-°C for 30 days. For hydrocarbons rate of biodegradation measurement, sterilized soil was distributed in petri dishes, 3% w/w of two crude oils and used car oil were added, separately and then supplemented with isolated strains (single and mixtures). One Petri dish was used as a control without any microbial addition. Absorbance was determined by spectrophotometer at 360 nm and at 340 nm for crude oils and used car oil, respectively. The effect of aeration, added NPK and added microbial degraders on biodegradation of Masila crude oil and used car oil was studied. Soil was supplemented with 20% Masila crude oil and used car oil, separately. The soil was distributed into containers. Container (1) was aerated twice a week, NPK 1:1:1 was added to container (2), mixture of all isolated strains with degrading capacity was added to container (3). Finally, NPK with continued aeration in addition to the microbial mixture were applied to the last container (4). One container was used as a control without any addition (soil and contaminant only). Colony Forming Unit (CFU) of total heterotrophic microbes and hydrocarbon utilizing microbes, PH and percentage of oils degradation were determined. 22 microbial strains were isolated and identified as, Achrombacter, Aeromonas, Klebsiella pneumonia, Pseudomonas, Corynebacterium, Penicillium, Enterobacteriaceae (Enteric rods), Actinobacillus, Streptomyces, budding yeast cells, Cladosporum and Geotrichum spp. The highest biodegradation result in Miri crude oil after 30 days were 54.33% and 84.61% for strain Z13 (Corynebacterium spp.) and microbial mixture of the strains isolated from Rawang and Serdang area (MS), respectively. While in Masila crude oil was 33.81% for Strain A3 (Klebsiella pneumonia) and 49.47% for microbial mixture of the strains isolated from Serdang (Smix). In used car oil biodegradation experiment, strain Z4 (Corynebacterium) had the highest degradation with 72.9%. While microbial mixture of the strains isolated from Kajang (Zmix) had 72.4 % of degradation. In the experiment of the effect of aeration, added NPK and added microbial degraders on biodegradation, the aerated container showed 56.62% of degradation after 42 days in Masila crude oil, while the container which contained NPK and was aerated and supplemented with isolated strains showed 66% degradation in used car oil. Generally, two bacterial species and one fungal species isolated were found to be effective degraders (Corynebacterium spp, Streptomyces spp. and Cladosporum spp,), respectively. The highest degradability by single strains was on used car oil which might be due to the adaptability of the isolated microbes to use it. The microbial mixtures showed higher effect on the biodegradation than the single strains. Aeration found to be the most important in the effect on the biodegradation results.
