Bioremediation and sustainability
Environmental Engineering and Management Journal, 2012Co-Authors: Romeela Mohee, Ackmez MudhooAbstract:Bioremediation consists in a fast growing and promising set of remediation techniques increasingly studied and applied in practical use for environmental clean-up. As a low cost alternative to conventional methods for treating wastes and contaminated media, Bioremediation offers the possibility to degrade these contaminats using natural microbial activity mediated by different consortia of microbes. On the other hand, the development of environmental management is promoted by sustainable development, which constantly promotes green technologies to treat a wide range of aquatic and terrestrial habitats contaminated due to anthropogenic activities with the main sources of contaminants. In this context, the book Bioremediation and Sustainability edited by Romeela Mohee and Ackmez Mudhoo provides a thorough inside into the the most cost-effective techniques in Bioremediation technologies and the most cutting-edge research on Bioremediation and its applications and discusses the sustainability paradigm and the role of green Bioremediation technologies in environmental science. The book comprises ten chapters, each of them dealing with different aspects of Bioremediation and sustainability. An up-to-date and comprehensive treatment of research and applications for some of the most important low-cost, green , emerging technologies in chemical and environmental engineering is provided. Chapter 1, Elements of Sustainability and Bioremediation, by Ackmez Mudhoo and Romeela Mohee is an introductory one and deals with the essential features of sustainability and the various in situ and ex situ Bioremediation techniques. This chapter also provides groundwork for the subsequent chapters dealing with Bioremediation, such as anaerobic digestion biotechnology, air-sparging, vermistabilization, bioleaching, biobleaching, and many others. Chapter 2, Natural Attenuation, by R. Ryan ...

A comprehensive overview of elements in Bioremediation
Reviews in Environmental Science and Bio Technology, 2010Co-Authors: Asha A. Juwarkar, Sanjeev K. Singh, Ackmez MudhooAbstract:Sustainable development requires the development and promotion of environmental management and a constant search for green technologies to treat a wide range of aquatic and terrestrial habitats contaminated by increasing anthropogenic activities. Bioremediation is an increasingly popular alternative to conventional methods for treating waste compounds and media with the possibility to degrade contaminants using natural microbial activity mediated by different consortia of microbial strains. Many studies about Bioremediation have been reported and the scientific literature has revealed the progressive emergence of various Bioremediation techniques. In this review, we discuss the various in situ and ex situ Bioremediation techniques and elaborate on the anaerobic digestion technology, phytoremediation, hyperaccumulation, composting and biosorption for their effectiveness in the biotreatment, stabilization and eventually overall remediation of contaminated strata and environments. The review ends with a note on the recent advances genetic engineering and nanotechnology have had in improving Bioremediation. Case studies have also been extensively revisited to support the discussions on biosorption of heavy metals, gene probes used in molecular diagnostics, Bioremediation studies of contaminants in vadose soils, Bioremediation of oil contaminated soils, Bioremediation of contaminants from mining sites, air sparging, slurry phase Bioremediation, phytoremediation studies for pollutants and heavy metal hyperaccumulators, and vermicomposting.

Bioremediation: An Eco-friendly Sustainable Technology for Environmental Management
Bioremediation of Industrial Waste for Environmental Safety, 2020Co-Authors: Christopher Chibueze Azubuike, Chioma Blaise Chikere, Gideon Chijioke OkpokwasiliAbstract:Evironmental pollution is a major public health concern due to the detrimental effects of pollutants to humans and to other living organisms. Chemical and physical methods of remediation are expensive and do not result in complete removal of pollutants. Moreover, both methods may lead to more pollution and site disruption, thus impacting negatively to humans and other biota in the immediate vicinity of the polluted site. Therefore, chemical and physical methods of remediation are not considered eco-sustainable. Unlike these methods, Bioremediation, which relies on biological processes (mediated by different groups of living organisms), results in the permanent removal of pollutants. This chapter covers: the eco-sustainable features of Bioremediation, pollutants that are susceptible to Bioremediation, groups of organisms that play significant roles in Bioremediation, and advantages of Bioremediation. Furthermore, it highlighted some limitations of Bioremediation and ways of overcoming the limitations. Together, the advantages of Bioremediation techniques notably its cost-effectiveness at different scales of operation, the simplicity of operation, process monitoring, and its less destructive features to polluted sites during operation are amongst the features that make Bioremediation an eco-sustainable technology for environmental management.

Bioremediation techniques–classification based on site of application: principles, advantages, limitations and prospects
World Journal of Microbiology and Biotechnology, 2016Co-Authors: Christopher Chibueze Azubuike, Chioma Blaise Chikere, Gideon Chijioke OkpokwasiliAbstract:Environmental pollution has been on the rise in the past few decades owing to increased human activities on energy reservoirs, unsafe agricultural practices and rapid industrialization. Amongst the pollutants that are of environmental and public health concerns due to their toxicities are: heavy metals, nuclear wastes, pesticides, green house gases, and hydrocarbons. Remediation of polluted sites using microbial process (Bioremediation) has proven effective and reliable due to its eco-friendly features. Bioremediation can either be carried out ex situ or in situ, depending on several factors, which include but not limited to cost, site characteristics, type and concentration of pollutants. Generally, ex situ techniques apparently are more expensive compared to in situ techniques as a result of additional cost attributable to excavation. However, cost of on-site installation of equipment, and inability to effectively visualize and control the subsurface of polluted sites are of major concerns when carrying out in situ Bioremediation. Therefore, choosing appropriate Bioremediation technique, which will effectively reduce pollutant concentrations to an innocuous state, is crucial for a successful Bioremediation project. Furthermore, the two major approaches to enhance Bioremediation are biostimulation and bioaugmentation provided that environmental factors, which determine the success of Bioremediation, are maintained at optimal range. This review provides more insight into the two major Bioremediation techniques, their principles, advantages, limitations and prospects.

Bioremediation of oil contaminated soil microbiological methods for feasibility assessment and field evaluation
Journal of Microbiological Methods, 1998Co-Authors: M T Balba, N Alawadhi, R AldaherAbstract:Abstract Bioremediation is emerging as a promising technology for the treatment of soil and groundwater contamination. The technology is very effective particularly in dealing with petroleum hydrocarbon contamination. However, Bioremediation is a site-specific process and feasibility studies are required before full-scale remediation can be successfully applied. The type and scale of the feasibility studies that will be needed are specific to the Bioremediation approach to be employed during full-scale clean-up operation. In all cases however, these studies have the same goals: to accurately determine if specific hydrocarbon contaminants are amenable to biological treatment and to determine the time and cost required to treat the contaminants of concern according to the regulated clean-up criteria. This contribution provides background information on the chemistry and microbiology of hydrocarbon contamination, discusses the prospective of using biological methods for addressing this problem and describes several microbiological methods which can be used for the feasibility assessment of soil Bioremediation. The focus of this chapter is to highlight the needs for the integration of laboratory data to full-scale Bioremediation.

in situ Bioremediation of monoaromatic pollutants in groundwater a review
Bioresource Technology, 2008Co-Authors: Mehrdad Farhadian, Cedric Vachelard, David Duchez, Christian LarrocheAbstract:Monoaromatic pollutants such as benzene, toluene, ethylbenzene and mixture of xylenes are now considered as widespread contaminants of groundwater. In situ Bioremediation under natural attenuation or enhanced remediation has been successfully used for removal of organic pollutants, including monoaromatic compounds, from groundwater. Results published indicate that in some sites, intrinsic Bioremediation can reduce the monoaromatic compounds content of contaminated water to reach standard levels of potable water. However, engineering Bioremediation is faster and more efficient. Also, studies have shown that enhanced anaerobic Bioremediation can be applied for many BTEX contaminated groundwaters, as it is simple, applicable and economical. This paper reviews microbiology and metabolism of monoaromatic biodegradation and in situ Bioremediation for BTEX removal from groundwater under aerobic and anaerobic conditions. It also discusses the factors affecting and limiting Bioremediation processes and interactions between monoaromatic pollutants and other compounds during the remediation processes.
