    2. Scaling Methods of Sediment Bioremediation Processes and Applications (pages 217–227)

      P. Adriaens, M.-Y. Li and A. M. Michalak

      Version of Record online: 29 JUN 2006 | DOI: 10.1002/elsc.200520127

      Dominant processes affecting the fate of contaminants in sediments are presented and the need for spatial extrapolation of microbial activity endpoints in sediments are demonstrated, as well as a comparison between an interpolation method that implicitly accounts for scaling effects (kriging) and a novel method that explicitly includes scaling assumptions (M-Scale).

    3. Microbially Driven Redox Reactions in Anoxic Environments: Pathways, Energetics, and Biochemical Consequences (pages 228–233)

      B. Schink

      Version of Record online: 29 JUN 2006 | DOI: 10.1002/elsc.200620130

      The potential for anaerobic microbial conversion of organic compounds has increased dramatically through the last years. Many compounds which were considered to be stable in the absence of oxygen have proven to be biodegradable. Key reactions involved in the destabilization were found to be basically different from those used by aerobic bacteria.

    4. Assessment of Microbial In Situ Activity in Contaminated Aquifers (pages 234–251)

      M. Kästner, A. Fischer, I. Nijenhuis, R. Geyer, N. Stelzer, P. Bombach, C. C. Tebbe and H. H. Richnow

      Version of Record online: 29 JUN 2006 | DOI: 10.1002/elsc.200620125

      Identifying the key microorganisms responsible for compound turnover is essential for the successful application of Natural Attenuation processes. Here, new details of two recently developed approaches concerning the assessment of in situ biodegradation are reviewed and presented in great depth.

    5. Dispersing Pollutant-Degrading Bacteria in Contaminated Soil without Touching it (pages 252–260)

      H. Harms and L. Y. Wick

      Version of Record online: 29 JUN 2006 | DOI: 10.1002/elsc.200620122

      Mechanical treatment of soil is energy inefficient and not feasible for the remediation of entire mega-sites. Methods and mechanisms are presented that are capable of dispersing catabolically active bacteria in soil and sediment without the need of ex-situ treatment.

    6. Earthworms as a Transient Heaven for Terrestrial Denitrifying Microbes: a Review (pages 261–265)

      H. L. Drake and M. A. Horn

      Version of Record online: 29 JUN 2006 | DOI: 10.1002/elsc.200620126

      In situ factors of the earthworm gut stimulate ingested denitrifiers to produce nitrogenous gases that are emitted by the earthworm. In addition to effecting the in vivo emission of nitrogenous gases, the unique microenvironment of the earthworm gut might also affect the fitness and diversity of certain members of the soil microbial biome.

    7. Real Time Insights into Bioprocesses Using Calorimetry: State of the Art and Potential (pages 266–277)

      T. Maskow and H. Harms

      Version of Record online: 29 JUN 2006 | DOI: 10.1002/elsc.200520123

      Calorimetry provides real time insights into dynamic biological processes. This information can be used to control technical and natural systems. A comprehensive survey of the recent trends in modern calorimetry and the possible new applications in biotechnology are reported, which have overcome some of the weaknesses of conventional calorimetry.

    8. Development of a New Biotechnological Basis for Improving Industrial Sustainability in Japan (pages 278–284)

      H. Ohtake, S. Yamashita and J. Kato

      Version of Record online: 29 JUN 2006 | DOI: 10.1002/elsc.200620124

      Industrial sustainability is a key means of reducing environmental impacts and improving the quality of our life. The integration of biotechnology into chemical manufacturing has the potential to reduce energy and material consumption as well as the emission of substances hazardous to health and the environment.

    9. Microbial Fuel Cells in Relation to Conventional Anaerobic Digestion Technology (pages 285–292)

      T. H. Pham, K. Rabaey, P. Aelterman, P. Clauwaert, L. De Schamphelaire, N. Boon and W. Verstraete

      Version of Record online: 29 JUN 2006 | DOI: 10.1002/elsc.200620121

      The biological fuel cell is an interesting and promising addition to already existing fuel cell types. In recent years, research activity in fuel cell technology has increased remarkably. An innovative technology, based on the use of microbial fuel cells, is considered as a new pathway for bioconversion processes towards electricity.

    10. Trace Metals in Anaerobic Granular Sludge Reactors: Bioavailability and Dosing Strategies (pages 293–301)

      M. H. Zandvoort, E. D. van Hullebusch, F. G. Fermoso and P. N. L. Lens

      Version of Record online: 29 JUN 2006 | DOI: 10.1002/elsc.200620129

      Trace elements, which are essential for life, are in the most cases metal ions required in cellular nutrition in small amounts. The usual metals that qualify as trace elements are Mn2+, Co2+, Zn2+, Cu2+, and Mo2+. Further knowledge in this field is indispensable for a rational dosage of these metals.

    11. Biomass Digestion in Agriculture: A Successful Pathway for the Energy Production and Waste Treatment in Germany (pages 302–309)

      P. Weiland

      Version of Record online: 29 JUN 2006 | DOI: 10.1002/elsc.200620128

      Anaerobic digestion is one of the few technologies that creates renewable energy, solves environmental problems, and may assist to save resources like mineral fertilizers. Today biogas production is an important part of the energy policy in many countries. In Germany, biogas production has become a new income branch in agriculture, which is exceedingly fast growing.

    12. Characterization of a Novel Glucoamylase from the Thermoacidophilic Archaeon Picrophilus torridus Heterologously Expressed in E. coli (pages 311–317)

      B. Schepers, V. Thiemann and G. Antranikian

      Version of Record online: 29 JUN 2006 | DOI: 10.1002/elsc.200620131

      The production of glucose from starch is a process preferentially run at high temperatures and low pH, for which stable amylolytic enzymes are needed in ton scales. Therefore, thermoacidophiles are an interesting source for robust enzymes enabling biocatalysis under non-conventional conditions.

    13. A Dual-Color Bacterial Reporter Strain for the Detection of Toxic and Genotoxic Effects (pages 319–323)

      N. Hever and S. Belkin

      Version of Record online: 29 JUN 2006 | DOI: 10.1002/elsc.200620132

      Environmental monitoring using whole-cell biosensors is attracting increasing attention, in view of the ability of live cells to report on the overall toxicity of a sample, rather than on its individual components. Here a novel twist to this concept is presented by describing an interesting single “dual purpose” bacterial reporter strain.
