Properties of hydrogels for immobilization of bacteria in a commercial microfluidic dioreactor

Creator:: Weymann, Davis
Abstract:: Current technological shortcomings limit the economic viability of capturing and utilizing small sources of methane. The development of a reactor to overcome these limitations would unlock economic opportunity and incentivize reduced methane emissions. A microfluidic bioreactor containing immobilized methanotrophs has the potential to overcome these limitations by profitably converting small...

Karl Jordan : a life in systematics

Creator:: Johnson, Kristin Renee
Abstract:: Karl Jordan (1861-1959) was an extraordinarily productive entomologist who influenced the development of systematics, entomology, and naturalists' theoretical framework as well as their practice. He has been a figure in existing accounts of the naturalist tradition between 1890 and 1940 that have defended the relative contribution of naturalists to the...

Machining and toxicological performance of a zinc oxide metalworking nanofluid

Creator:: Sahakian, Misha
Abstract:: Lower production costs are a common goal of many manufacturers as part of their continuous improvement strategies. A large portion of production costs for manufacturers is the machining of metals to form components. Metal machining is accompanied by friction and heat which is dealt with using metalworking fluids such as...

Integrating sustainable manufacturing assessment into decision making for a production work cell

Creator:: Zhang, Hao
Abstract:: Sustainability has been the focus of intense discussions over the past two decades, with topics around the entire product life cycle. In the manufacturing phase, research has been focused solely on environmental impact assessment or environmental impact and cost analysis in its assessment of sustainability. However, few efforts have investigated...

Effect of Tannic Acid on the Transcriptome of the Soil Bacterium Pseudomonas protegens Pf-5

Creator:: Lim, Chee Kent, Penesyan, Anahit, Hassan, Karl A., Loper, Joyce E., and Paulsen, Ian T.
Abstract:: Tannins are a diverse group of plant-produced, polyphenolic compounds with metal-chelating and antimicrobial properties that are prevalent in many soils. Using transcriptomics, we determined that tannic acid, a form of hydrolysable tannin, broadly affects the expression of genes involved in iron and zinc homeostases, sulfur metabolism, biofilm formation, motility, and...

The effect of zinc limitation on the transcriptome of Pseudomonas protegens Pf-5

Creator:: Lim, Chee Kent, Hassan, Karl A., Penesyan, Anahit, Loper, Joyce E., and Paulsen, Ian T.
Abstract:: Zinc is an important nutrient but can be lacking in some soil environments, influencing the physiology of soil-dwelling bacteria. Hence, we studied the global effect of zinc limitation on the transcriptome of the rhizosphere biocontrol strain Pseudomonas protegens Pf-5 (formerly Pseudomonas fluorescens). We observed that the expression of the putative...
