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

Microbial Diversity in the Genomic Era presents insights on the techniques used for microbial taxonomy and phylogeny, along with their applications and respective pros and cons. Though many advanced techniques for the identification of any unknown bacterium are available in the genomics era, a far fewer number of the total microbial species have been discovered and identified to date. The assessment of microbial taxonomy and biosystematics techniques discovered and practiced in the current genomics era with suitable recommendations is the prime focus of this book. Discusses the techniques used for microbial taxonomy and phylogeny with their applications and respective pros and cons Reviews the evolving field of bacterial typing and the genomic technologies that enable comparative analysis of multiple genomes and the metagenomes of complex microbial environments Provides a uniform, standard methodology for species designation

The Water Research Institute at the Technion (Israel Institute of Technology) is proud to have initiated and sponsored the International Workshop "Soil and Aquifer Pollution: Non-Aqueous Phase Liquids - Contamination and Recla- tion", held May 13th-15th, 1996, on the Technion campus in Haifa. Groundwater contamination is one of the pressing issues facing Israel and other countries which depend on groundwater for water supply. In Israel, 60% of the water supply comes from groundwater, most of it from two large aquifers. The Coastal Aquifer underlies the area where the largest concentration of human activity already takes place, and where much of future development is expected to occur. It is a phreatic sandstone aquifer, vulnerable to pollution from activities at the surface. The Mountain Aquifer is recharged in the higher terrain to the east, and flows, first in a phreatic zone, then confined, westward and underneath the Coastal Aquifer. This limestone aquifer has higher permeabilities and flow velo- ties, so pollution can reach the groundwater quite readily. Smaller local aquifers are also important components in the national water system. While measures are taken to protect these aquifers from pollution, there are locations where contamination has already occurred. Furthermore, accidental pollution may not be totally avoided in the future. Therefore, understanding the processes of groundwater contamination, recommending the proper measures for preventing it, and determining the best means for reclamation once pollution has occurred, are of great practical importance. Non-aqueous phase liquids (NAPLs) are among the most significant contaminants.

Around the World, metal pollution is a major problem. Conventional practices of toxic metal removal can be ineffective and/or expensive, delaying and exacerbating the crisis. Those communities dealing with contamination must be aware of the fundamentals advances of microbe-mediated metal removal practices because these methods can be easily used and require less remedial intervention. This book describes innovations and efficient applications for metal bioremediation for environments polluted by metal contaminates.

Novel Insights Into Freshwater Hydrocarbon rich Sediments Using Metatranscriptomics Opening the Black Box

Abstract: Baseline biogeochemical surveys of natural environments is an often overlooked field of environmental studies. Too often research begins once contamination has occurred, with a knowledge gap as to how the affected area behaved prior to outside (often anthropogenic) influences. These baseline characterizations can provide insight into proposed bioremediation strategies crucial in cleaning up chemical spill sites or heavily mined regions. Hence, this study was conducted to survey the in-situ microbial activity within freshwater hydrocarbon-rich environments cutting through the McMurray formation - the geologic strata constituting the oil sands. We are the first to report in-situ functional variations among these freshwater microbial ecosystems using metatranscriptomics, providing insight into the in-situ gene expression within these naturally hydrocarbon-rich sites. Key genes involved in energy metabolism (nitrogen, sulfur and methane) and hydrocarbon degradation, including transcripts relating to the observed expression of methane oxidation are reported. This information provides better linkages between hydrocarbon impacted environments, closing knowledge gaps for optimizing not only oil sands mine reclamation but also enhancing microbial reclamation strategies in various freshwater environments. These finding can also be applied to existing contaminated environments, in need of efficient reclamation efforts. Graphical abstract: Highlights: Baseline metatranscriptomics survey of freshwater naturally hydrocarbon-rich sediments. Gene expression analysis indicating possible bioindicator genes for degradation. Complex array of substituted and unsubstituted aromatic hydrocarbons. Syntrophic metabolic processes are governing both energy and contaminant degradation. Insights into natural microbial biodegradation of hydrocarbons.

Obwohl oder gerade weil eine kaum mehr überschaubare Zahl von Publi kationen auf dem Gebiet der Immobilisierung von Biokatalysatoren existiert, ist es für den Anfänger, der einen Einstieg sucht, auf diesem Gebiet oft schwer, geeignete Informationen aus der Flut von Originalarbeiten herauszufinden. Einige gute, fast immer aber eng lischsprachige Monographien sind entweder außerordentlich umfang reich und teuer, oder sie behandeln nur ausgewählte Teilaspekte der Immobilisierung. Dem will die vorliegende Einführung abhelfen. Sie soll dem Leser zu einem raschen Überblick verhelfen und ihm den inzwischen abgesicherten Kenntnisstand nach Art eines kurzen Lehr buches vermitteln. Das Buch ist aus Erfahrungen in Vorlesungen, Praktika und Kursen entstanden. Es soll sich maßgeblich an Lernende wenden, auch wenn "Immobilisierte Biokatalysatoren" bisher noch nicht zum Stan dardrepertoire der Lehre an deutschen Universitäten und Fachhoch schulen gehören. Es ist jedoch die Oberzeugung des Autors, daß sich dies in den kommenden Jahren mit der wachsenden Bedeutung dieses Gebietes und mit der allgemeinen Etablierung der Biotechnologie an den Hochschulen ändern wird. Ober den Kreis der Studenten und Dozen ten hinaus wendet sich die Einführung aber auch an die vielen Natur wissenschaftler und Techniker der industriellen Praxis, die sich mit immobilisierten Biokatalysatoren befassen und sich dazu ein ent sprechendes Grundwissen aneignen wollen.

In den letzten 25 Jahren kamen in zunehmendem Maße neue synthetische Werkstoffe für zahlreiche Verwendungszwecke in Gebrauch, über deren V erhalten gegenüber pflanzlichen und tierischen Schädlingen erst Erfah rungen gesammelt werden mußten, ehe es möglich war, Prüfmethoden und Schutzmaßnahmen zur Verhinderung der biologischen Zerstörung dieser Materialien zu entwickeln. Seither sind über diese Themen zahlreiche V er öffentlichungen erschienen, und das Wissen auf diesem zwischen der Bio logie, der organischen Chemie, der Toxikologie und der Werkstoffkunde stehenden Gebiet hat eine gewisse Abrundung erfahren. Es erscheint deshalb nützlich, diesen Wissenstoff, der in den Buch- und Zeitschriftenveröffent lichungen der genannten Disziplinen und deren Teilgebieten erschienen ist, geschlossen darzustellen, was naturgemäß nicht ohne ein kurzes Eingehen auf das V erhalten, die Prüfung und die Konservierung der natürlichen organischen Werkstoffe möglich war. Es wurde als wichtig angesehen, dem Chemiker und Anwendungs techniker einen Überblick über die als Schädlinge in Betracht kommenden Organismen zu geben; doch ist es nicht der Sinn dieser Schrift, die Aufgabe der biologischen Bestimmungsbücher zu übernehmen. Für den Biologen werden die Angaben über Prüfmethoden und die Kultivierung der Prüf organismen von Wert sein. Die im Anhang wiedergegebenen Rezepte der Nährmedien dürften dem Fachmann gestatten, Prüfungen von Werkstoffen mit pflanzlichen und tierischen Schädlingen auszuführen, ohne dabei auf die Originalliteratur zurückgreifen zu müssen. Sollte die vorliegende Schrift darüber hinaus die Chemiker und Anwendungstechniker auf dem Kunst stoffgebiet zur Beschäftigung mit der biologischen Zerstörung der makro molekularen Werkstoffe anregen, so hat sie ihren Zweck erfüllt.
