Abstract:

Soil microbial communities are affected extensively by addition of amendments to their environment. Of particular concern is the addition of poultry litter, which contains a substantial C, energy, and nutrient supply, but also antibiotic resistance genes (ARG), antimicrobials, and a multitude of microbial species. This project seeks to primarily assess if there is a change in bacterial community structure in response to poultry litter amendments to pasture land across geographically independent land across northern Georgia. It may be that changes in the relative abundance of bacterial communit

Abstract:

Background: MicrO is an ontology of microbiological terms, including prokaryotic qualities and processes, material entities (such as cell components), chemical entities (such as microbiological culture media and medium ingredients), and assays. The ontology was built to support the ongoing development of a natural language processing algorithm, MicroPIE (or, Microbial Phenomics Information Extractor). During the MicroPIE design process, we realized there was a need for a prokaryotic ontology which would capture the evolutionary diversity of phenotypes and metabolic processes across the tree of

Abstract:

With the advent of next generation sequencing there has been an explosion of the size of data that needs to be processed, where next generation sequencing yields basepairs of DNA in the millions. The rate at which the size of data increases supersedes Moores law therefore there is a huge demand for methods to nd meaningful labels of sequenced data. Studies of microbial diversity of a sample is one such challenge in the eld of metagenomics. Finding the distribution of a bacterial community has many uses for example, obesity control. Existing methods often resort to read-by-read classication whi

Field and laboratory microcosm responses of indigenous microbial communities exposed to municipal sewage treatment plant (STP) effluent were monitored. The STP effluent produced increased adenylate concentrations, ATP/ADP and ATP/Chla ratios, and decreased Chla, Chla/Pheo, d, and species richness relative to upstream reference comm

Abstract:

<p> Microbial life represents the majority of the diversity of life on planet earth. Microbes are found in all ecosystems. The microbial community of an ecosystem can be an indicator of its health and the foundation of the ecosystem function. Thus, an understanding of the microbial community of an ecosystem is vital to understanding the ecosystem itself. To fully grasp the microbial community structure, it is essential to understand the factors that shape the community composition and diversity of the ecosystem. This works focusses on the primary drivers of microbial composition in three ecosy

Abstract:

Cyanobacteria are a group of photo-oxygenic bacteria found in nearly every ecosystem, but much cyanobacterial diversity, in various habitats, has yet to be explored. Cyanobacteria are often conspicuous components of photosynthetic flora, providing significant carbon and nitrogen inputs to surrounding systems. As possible primary colonizers of stone substrates not native to this region, cyanobacteria isolated from headstones may provide biogeographically informative data. An exploratory study of lichen-dominated microbial consortia, growing on headstones, was conducted to isolate and identify n

Abstract:

Background: The large-scale analysis of phenomic data (i.e., full phenotypic traits of an organism, such as shape, metabolic substrates, and growth conditions) in microbial bioinformatics has been hampered by the lack of tools to rapidly and accurately extract phenotypic data from existing legacy text in the field of microbiology. To quickly obtain knowledge on the distribution and evolution of microbial traits, an information extraction system needed to be developed to extract phenotypic characters from large numbers of taxonomic descriptions so they can be used as input to existing phylogene

Abstract:

<p>Although there are many examples of microbial biogeography, few microbes have been studied at high taxonomic resolution over large spatial scales. As a result, the environmental and ecological processes that drive niche partitioning, diversity, composition, and activity of microbial taxa are often poorly understood. To address this gap, I examine the most abundant phytoplankton in the global ocean, Prochlorococcus sp., a marine cyanobacterium.

Microbial ecology seeks to describe the diversity and distribution of microorganisms in various habitats within the context of environmental variables. High throughput sequencing has greatly boosted the number and scope of projects aiming to study and analyse these organisms, with ever-increasing amounts of data being generated. Amplicon based taxonomic analysis, which determines the presence of microbial taxa in different environments on the basis of marker gene annotations, often uses percentage identity as the main metric to determine sequence similarity against databases.
