Metabolic engineering of Shewanella oneidensis MR-1 for microbial fuel cell application

Creator:: Hall, Robert G. (Robert George)
Abstract:: Shewanella oneidensis MR-1 is a gram-negative, facultative anaerobic bacteria with the capability of dissimilatory metal reduction. The ability of the organism to reduce a wide range of solid metal-oxides during anaerobic respiration makes it an ideal candidate for the powering of microbial fuel cells (MFCs), which capture the electrons discharged...

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...

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...

Hemicellulose utilization by yeast for ethanol production- adaptation, effect of inhibitors and a flux balance based analysis

Creator:: Avanasi Narasimhan, Ragothaman
Abstract:: A major challenge in ethanol production using lignocellulosic feed stock is inefficient utilization of hemicellulose, which accounts for 30-40% of lignocellulosic biomass. Xylose, comprising >60% of recoverable sugars from hemicellulose is a major product of the hemicellulose hydrolysis. Utilization of this carbon source would significantly increase the ethanol yield from...

Microbial Electrolysis Cells for the Production of Hydrogen Gas : Evaluation of Internal Resistance and Design for Scale-Up

Creator:: Miller, Andrew G.
Abstract:: Modification of microbial electrolysis cells (MECs) by altering the sizes of the anode and the cathode, or their interaction with the liquid stream affects the performance of the MEC, but it remains difficult to quantify how much each change will contribute to the overall performance. Through this study, a method...

Evaluating the Sustainability of an Advanced Biofuel Using Attributional and Consequential Life Cycle Assessments

Creator:: McDaniel, Allexander M.
Abstract:: Attributional and consequential life cycle assessments are useful in evaluating the environmental impacts of a process, product, or decision. Both types of life cycle assessments differ however in their scope and their ability to answer specific questions. In order to fully understand and compare the environmental impacts of a sugarcane...

Energy recovery from biodiesel waste : performance of microbial electrochemical systems on glycerol

Creator:: Chignell, Jeremy
Abstract:: Pure glycerol and the crude waste glycerin byproduct of biodiesel production were tested as substrates for electricity production in single-chamber, air-cathode microbial fuel cells (MFCs) and in single-chamber microbial electrolysis cells (MECs), using pure and mixed microbial cultures as anode biocatalyst. Current densities of 0.40 A/m² and 0.13 A/m² were...

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,...
