This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: DNA-based evaluations of 3-CB-degrading sediment communities revealed that the structures of the adapted communities continued to change after degrading 3-CB for months. These evaluations also suggested that communities that share a common inoculum, but independently develop the ability to transform a chlorinated substrate, exhibit unique overall structures, yet share some common populations. Thus, the presence of the common populations may be necessary for a community to adapt to a chlorinated substrate.

Available in PDF, EPUB and Kindle. Book excerpt: The metabolic pathway of oxygenic photosynthesis is fueled by sunlight and the oxidation of water; oxygen is produced as a waste product. Before the rise of oxygenic phototrophs 2.3 billion years ago, microbes utilized anoxygenic photosynthesis to form organic carbon compounds using electron donors such as iron [Fe(II)] and reduced sulfur compounds. Anoxygenic phototrophs can be found in modern environments like meromictic lakes. We studied enrichment cultures of microorganisms driven by anoxygenic photosynthesis to determine whether and how they use another possible electron donor, manganese [Mn(II)]. Cultures reduced with sulfide [H2S] and enriched with Mn(II) as a potential electron donor oxidized Mn(II) and formed various manganese oxide minerals in the presence of light. To further characterize these anaerobic microbial communities and the role of manganese, we grew the cultures on different concentrations of Mn(II) and H2S and isolated individual microbes. We characterized the composition of the microbial communities by extracting copies of a specific gene, 16S rRNA, which is highly conserved and a standard species-identifying marker. Communities grew only in the presence of light and obligately anaerobic green sulfur bacteria from the phylum Chlorobi were the only phototrophic organisms. From these communities, we identified several taxa using 16S rRNA gene and whole genome sequencing; most notably, a taxon belonging to Chlorobi identified as Chlorobium limicola and a taxon belonging to Desulfomicrobium identified as Desulfomicrobium baculatum. We found a robust microbial community capable of oxidizing Mn(II) in the absence of molecular oxygen. These communities are driven by anoxygenic photosynthesis and dependent on the concentration of sulfur sources, like sulfide. Optimal conditions for anaerobic oxidation of Mn(II) suggest this process occurs in source environment.

Download or read book Organohalide Respiring Bacteria written by Lorenz Adrian and published by Springer. This book was released on 2016-08-03 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the current state of knowledge concerning bacteria that use halogenated organic compounds as respiratory electron acceptors. The discovery of organohalide-respiring bacteria has expanded the range of electron acceptors used for energy conservation, and serves as a prime example of how scientific discoveries are enabling innovative engineering solutions that have transformed remediation practice. Individual chapters provide in-depth background information on the discovery, isolation, phylogeny, biochemistry, genomic features, and ecology of individual organohalide-respiring genera, including Dehalococcoides, Dehalogenimonas, Dehalobacter, Desulfitobacterium and Sulfurospirillum, as well as organohalide-respiring members of the Deltaproteobacteria. The book introduces readers to the fascinating biology of organohalide-respiring bacteria, offering a valuable resource for students, engineers and practitioners alike.
