It has for some years been clear that most microorganisms in biological wastewater systems cannot be reliably identified and quantified by conventional microscopy or by traditional culture-dependent methods such as plate counts. Therefore, molecular FISH Handbook biological methods are vital and must be introduced instead of, or in addition to, conventional methods. At present, FISH is the most widely used and best tested of these methods. This handbook presents all relevant information from the literature and, based on the extensive experience of the authors, advice and recommendations are given for for Biological reliable FISH identification and quantification. The overall purpose of the book is to help scientists, consultants, students, and plant operators to get an overview of important microorganisms in biological wastewater Wastewater Treatment treatment and to explain how FISH can be used for detecting and quantifying these microbes. A proper and reliable identification of dominant microorganisms is of great importance for research and new developments in the wastewater treatment industry, Identification and quantification of microorganisms and it is important for optimization and troubleshooting of operational problems in present wastewater treatment plants. in activated sludge and biofilms by FISH The book encompasses an overview of dominant microorganisms present in the wastewater treatment systems, which oligonucleotide probes (gene probes) to select for detection of these microbes by FISH, how to perform FISH (detailed protocols), how to Editor(s): Per Halkjær Nielsen, Holger Daims and Hilde Lemmer quantify the microbes, and how to solve common problems of FISH. The book addresses several functional groups: nitrifiers, denitrifiers, polyphosphate-accumulating organisms, glycogen-accumulating organisms, bacteria involved in hydrolysis and fermentation, filamentous bacteria from bulking sludge, and scum-forming bacteria. A comprehensive collection of FISH-images showing dominant representatives of these groups helps readers to use FISH in the context of wastewater treatment.

SOD is not one, but three separate, non-homologous 12 enzymes that perform the same function. Thus, the evolutionary history of genes encoding for 13 different SOD enzymes is one of convergent evolution, which reflects environmental selection 14 brought about by an oxygenated atmosphere, changes in metal availability, and opportunistic 15 horizontal gene transfer (HGT). In this study we examine the phylogenetic history of the protein 16 sequence encoding for the nickel-binding metalloform of the SOD enzyme (SodN). A comparison 17 of organismal and SodN protein phylogenetic trees reveals several instances of HGT, including 18 multiple inter-domain transfers of the sodN gene from the bacterial domain to the archaeal domain.

Mixed microbial consortia (MMC) are known to be able to produce PHAs from organic waste streams. Knowledge of key-microbes and their characteristics in PHA-producing consortia is necessary for further process optimization and direction towards synthesis of specific types of PHAs. In this study, a PHA-producing mixed microbial consortium (MMC) from an industrial pilot plant was characterized and further enriched on acetate in a laboratory-scale selector with a working volume of 5 L.

Read Full License Page 1/25 Abstract Background: Herbaceous insects are one of the main biological threats to crops. One such group of insects, stink bugs, do not eat large amounts of tissue when feeding on soybean, but are extremely damaging to the quality of the seed yield as they feed directly on green developing seeds leading to poorly marketable harvests. In addition to causing physical damage to the seed during feeding, the insects can also transmit microbial pathogens, leading to even greater yield loss. Conducting surveys of the insect intestinal microbiome can help identify possible pathogens, as well as detail what healthy stink bug digestive systems have in common.

  • Novel Nitrite Reductase Domain Structure Suggests a Chimeric
    Novel nitrite reductase domain structure suggests a chimeric denitrification repertoire in Phylum Chloroflexi Sarah Schwartz1, Lily Momper1, L. Thiberio Rangel1, Cara Magnabosco2, Jan Amend3, and Gregory Fournier1 1Massachusetts Institute of Technology 2ETH Zurich 3University of Southern California June 11, 2021 Abstract Denitrification plays a central role in the global nitrogen cycle, reducing and removing nitrogen from marine and terrestrial ecosystems. The flux of nitrogen species through this pathway has a widespread impact, affecting ecological carrying capacity, agriculture, and climate. Nitrite reductase (Nir) and nitric oxide reductase (NOR) are the two central enzymes in this pathway. Here we present a previously unreported Nir domain architecture in members of Phylum Chloroflexi. Phylogenetic analyses of protein domains within Nir indicate that an ancestral horizontal transfer and fusion event produced this chimeric domain architecture. We also identify an expanded genomic diversity of a rarely reported nitric oxide reductase subtype, eNOR. Together, these results suggest a greater diversity of denitrification enzyme arrangements exist than have been previously reported.
