Studies in preparative chromatography

Creator:: Zhang, Ling
Abstract:: Preparative chromatography is the most widely used purification method in the biotechnology and pharmaceutical industry. Here, one theoretical and one practical problem of preparative chromatography are investigated. The theoretical problem deals with the effect of experimental error on the precision of adsorption isotherm parameters estimated by numerical method. Numerical method...

Bacterial community analysis, new exoelectrogen isolation and enhanced performance of microbial electrochemical systems using nano-decorated anodes

Creator:: Xu, Shoutao
Abstract:: Microbial electrochemical systems (MESs) have attracted much research attention in recent years due to their promising applications in renewable energy generation, bioremediation, and wastewater treatment. In a MES, microorganisms interact with electrodes via electrons, catalyzing oxidation and reduction reactions at the anode and the cathode. The bacterial community of a...

A network approach for the mechanistic classification of bioactive compounds

Creator:: Siebert, Trina A.
Abstract:: Using network architecture to describe a biological system is an effective organizational method. The utility of this approach, which generally applies to qualitative models, is enhanced by the addition of quantitative models characterizing the interactions between network nodes. A chromatophore-based signal transduction network is developed, and the highly interconnected major...

Optimization of environmental conditions and electron flow for enhanced hydrogen production by cyanobacterial species Synechocystis sp. PCC 6803

Creator:: Burrows, Elizabeth H.
Abstract:: Many conditions affecting hydrogen (H₂) production by the cyanobacterium, Synechocystis sp. PCC 6803, were optimized to yield maximum H₂ accumulation. Biological H₂ production from photosynthetic species is a promising form of renewable energy since an abundant supply of sunlight hits the Earth every day, and photosynthetic bacteria can harness this...

Monte Carlo random walk simulation as a complement to experimental and theoretical approaches : application to mass transfer in fish muscle tissue

Creator:: Almonacid-Merino, Sergio Felipe
Abstract:: Mass transfer processes in food systems, such as solute infusion, are poorly understood because of their complex nature. Food systems contain porous matrices and a variety of continuous phases within cellular tissues. Mass transfer processes are generally not pure diffusion: often convection, binding and obstructing diffusion will occur. Monte Carlo...

Photobiological hydrogen production from the cyanobacterium Synechocystis sp. PCC 6803 encapsulated in sol-gel processed silica

Creator:: Dickson, David J.
Abstract:: Photobiological hydrogen production from live cells of the cyanobacterium Synechocystis sp. PCC 6803 encapsulated in silica gel was investigated. Hydrogen is a dense energy carrier with potential to reduce dependence on fossil fuels, provided a renewable and sustainable means of production can be achieved. Under certain conditions, Synechocystis sp. PCC...

Metabolic engineering of cyanobacteria to optimize photobiological hydrogen production

Creator:: Luterra, Markael
Abstract:: Photobiological hydrogen production -- the use of photosynthesis to split water into hydrogen and oxygen -- presents an opportunity for efficient and large-scale solar biofuel development. One of the major challenges in this area is competition for reductant between the hydrogen-evolving hydrogenase enzyme and other metabolic pathways. In this work...

Model Predictive Control for Optimum Algal Growth

Creator:: Juneja, Ankita
Abstract:: Microalgae has been under careful consideration as a sustainable feedstock for renewable fuel recently due to its year round production with high energy yields per unit area, reduced need for arable land, water treatment benefits with nutrient cycling, and minimal competition with the food industry. Despite of all these advantages,...

Electrical Conductivity in Mixed-Species Biofilms for Enhancing Energy Generation in Anaerobic Microbial Systems

Creator:: Li, Cheng
Abstract:: Further enhancement of energy generation is desired for practical application of anaerobic microbial systems such as microbial fuel cells (MFC) and anaerobic digesters (AD). A possible approach is to enhance the ability of microbial communities to transfer electron extracellularly in the form of electrical current. Critical to perform direct extracellular...

Enhancing hydrogen production in microbial electrolysis cells through development of platinum-free cathode and improvement of reactor design

Creator:: Hu, Hongqiang
Abstract:: Microbial electrolysis provides a new approach for hydrogen generation from renewable biomass. At current stage, the most likely limiting factors for successful scale up of this technology are the large internal resistance and high fabrication cost. This dissertation presents an attempt to overcome these limitations by investigating novel microbial electrolysis...
