Book excerpt: The San Jacinto River system south of the I-10 overpass is heavily contaminated with biphenyl and polychlorinated biphenyls (PCBs), carcinogenic aromatic hydrocarbons that have a deleterious impact on the environment. While typically recalcitrant to most forms of environmental degradation, biphenyl and PCBs compounds are known to share a common microbial degradation pathway with other chlorinated aromatics such as polychlorinated dioxin (PCDD) and dibenzofuran (PCDF). As such the purpose of this research is to isolate and test bacterial strains collected from contaminated San Jacinto River sediment and soil for the capacity to degrade or fully metabolize biphenyl and its derivatives. As conventional clean-up is expensive, such strains can be used in the field of bioremediation as a more cost-effective way of treating environmental contamination. The samples were screened for six weeks in minimal media with putative positive samples isolated for further bioinformatics analysis. Microorganisms identified as Pseudomonas pseudoalcaligenes, Pseudomonas nitroreducens, and Comamonas sp. were noted to harbor a putative 2,3 biphenyl dioxygenase enzyme and were further assessed for possible degradative capacity through a combination of growth kinetics and GC-MS analysis to determine the quality and quantity of the intermediate metabolites. Sample growth results suggest that each of the three isolated study strains are unable to utilize biphenyl or 3-chlorobiphenyl as a sole carbon source. In addition, expected metabolites of biphenyl degradation were not observed in either the supernatant or cell lysate indicating that expression of these putative 2,3 biphenyl dioxygenase enzymes and/or their catalytic activity against biphenyl is likely to be minimal.

Book excerpt: "Uptake of benzoic acid by BRI 3010 and BRI 6011 was inducible, exhibited saturation kinetics and the substrate was accumulated intracellularly against a concentration gradient by a factor of 8 and 10, respectively, indicative of active transport. Uptake of 2,4-DCBA by BRI 6011 was constitutive and saturation kinetics were not observed, suggesting passive diffusion of 2,4-DCBA and other CBAs into the cell down a concentration gradient." --

This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Kalamazoo River is contaminated with polychlorinated biphenyls (PCBs) which are neurotoxins and suspected carcinogens. The goal of this study was to isolate, identify, and metabolically characterize PCB degrading strains of aerobic bacteria. Biphenyl enrichments resulted in the isolation of putative PCB degrading strains from different locations along the river. Based on 16S rRNA gene analysis the isolated strains were identified as belonging to the genera of Achromobacter, Acidovorax, Cellulosimicrobium, Paenibacillus, Pseudomonas, and Rhodococcus. These strains were screened for the PCB degrading ability and congener specificity. All of the isolated strains degraded PCBs via the 2,3-dioxygenase pathway. The range of PCBs degraded was limited to mono- to tri-substituted congeners. In addition, the isolated strains oxidized 2,4'-CB but accumulated problematic intermediate metabolites. These results indicate that most of the aerobic-PCB-degrading bacteria isolated in this study from the Kalamazoo River have a moderate potential to degrade the lesser chlorinated PCBs, while one strain (D1) was found to have above average PCB-degrading capabilities.

This book was released on 2022-05-03 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explains the recent findings on the mutualistic plant–microbe interactions and how they can be utilized for sustainable agriculture practices including land reclamation. The book covers mainly plant growth promoting microorganisms (PGPMs) including both the symbiotic bacteria and fungi and their role in mobilization of nutrients, providing protection to the crops from phytopathogens and abiotic stresses. PGPMs play important roles in survival and health of the plant. These useful microorganisms provide plants with nutrients, protect them from pathogens and help them combat abiotic stresses. It is important that these mutualistic interactions between plant and soil microbes are well understood so as to develop reliable products in the form of biostimulants and biopesticides, as well as managing biotic and abiotic stresses in crops. Apart from enhancing crop productivity plant–microbe interactions can also perform activities such as reclamation of degraded lands, degradation of pollutants and remediation of saline or marginal lands. This book is of interest to teachers, researchers, plant scientists and microbiologists. Also, the book serves as additional reading material for undergraduate and graduate students of agriculture, microbiology, biotechnology, ecology, soil science and environmental sciences.

Book excerpt: Microbial Biodegradation and Bioremediation brings together experts in relevant fields to describe the successful application of microbes and their derivatives for bioremediation of potentially toxic and relatively novel compounds. This single-source reference encompasses all categories of pollutants and their applications in a convenient, comprehensive package. Our natural biodiversity and environment is in danger due to the release of continuously emerging potential pollutants by anthropogenic activities. Though many attempts have been made to eradicate and remediate these noxious elements, every day thousands of xenobiotics of relatively new entities emerge, thus worsening the situation. Primitive microorganisms are highly adaptable to toxic environments, and can reduce the load of toxic elements by their successful transformation and remediation. - Describes many novel approaches of microbial bioremediation including genetic engineering, metagenomics, microbial fuel cell technology, biosurfactants and biofilm-based bioremediation - Introduces relatively new hazardous elements and their bioremediation practices including oil spills, military waste water, greenhouse gases, polythene wastes, and more - Provides the most advanced techniques in the field of bioremediation, including insilico approach, microbes as pollution indicators, use of bioreactors, techniques of pollution monitoring, and more

Book excerpt: Polychlorinated Biphenyls (PCBs) are synthetic chlorinated hydrocarbon compounds, produced commercially since 1929 for use in a variety of products including plastics and adhesives, surface coatings, inks, flame retardants, pesticides and paints. PCBs are environmentally persistent, and accumulate in the food chain. They are designated by the Stockholm Convention on Persistent Organic Pollutants as persistent pollutants, and many countries have severely restricted or banned the production of PCBs. This report evaluates the effects of PCBs on human health, caused due to exposure by inhaling contaminated air or ingesting contaminated food and water.

Available in PDF, EPUB and Kindle. Book excerpt: Halogenated organic compounds constitute one of the largest groups of environmental chemicals. The industrial production of new halogenated organic compounds has increased throughout the last century peaking in the 1960s, and continuing in widespread use today. Organohalides are integral to a variety of industrial applications, including use as solvents, degreasing agents, biocides, pharmaceuticals, plasticizers, hydraulic and heat transfer fluids, and intermediates for chemical synthesis, to name a few. It is important to recognize the beneficial aspects of halogenated organic compounds, as well as their potentially deleterious impact on the environment and health. Recognition ofthe adverse environmental effects ofmanytypes oforganohalide compounds has led to efforts to reduce or eliminate the most problematic ones. Although organohalide compounds are typically considered to be anthropogenic industrial compounds, they have their counterpart in several thousands of natural biogenic and geogenic organohalides, representing most classes of organic chemicals. Natural sources account for a significant portion of the global organohalogen budget. This volume authored by recognized experts in the field provides a current perspective on how both natural and synthetic organohalides are formed and degraded, and how these processes are incorporated into a global halogen cycle. The focus is on microbial processes, since these play a major role both in the production and degradation, i. e. , cycling of halogenated organic compounds inthe environment. This book is organized into five parts. Part I, Introduction, provides a global perspective on the issues of organohalides and their fate in the environment.
