Flux Balance Analysis of Synechocystis PCC 6803.

Creator:: Elder, Robert M.
Abstract:: In order to improve photosynthetic hydrogen production, initial work has begun on a flux balance analysis of Synechocystis sp. strain PCC 6803, a model H2-producing organism. The mathematical model developed includes reactions relevant to photoautotrophic growth: glycolysis, the tricarboxylic acid cycle, the Calvin cycle, the photosynthetic electron transport chain, the...

Use of elicitor sets to characterize cellular signal transduction networks

Creator:: Narayanan, Arthi
Abstract:: Intracellular signaling cascades can no longer be viewed as linear pathways that relay and amplify information. Often, components of different pathways interact, resulting in signaling networks. The interactions of different pathways and the dynamic modulation of the activities of the components within signaling pathways can create a multitude of biological...

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...

Modeling and Validation of Denitrification Bioreactors for Agricultural Tile Drainage

Creator:: Morkoc, Adnan
Abstract:: Agricultural tile drainage is one of the major causes of increasing nitrate (NO3-) concentrations in surface water bodies thanks to the usage of nitrogen fertilizers and manure. Denitrifying bioreactors are constructed at the edge of agricultural lands in order to remove NO3- from drainage water through labile carbon substrates intended...

Proposal of an Automated Workflow for Appropriate Tile Drainage Simulation in Denitrifying Bioreactor Planning and Design

Creator:: Grohman, Travis A.
Abstract:: Denitrifying bioreactors are an edge-of-field treatment technology particularly well suited for nitrate removal from subsurface (tile) drainage effluent of agricultural lands. The effectiveness of a proposed denitrifying bioreactor is site-specific and depends upon the complicated interplay of field and environmental parameters controlling discharge events, nitrate concentrations, subsurface temperatures, dissolved oxygen...

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...

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...

The Genomic Capabilities of Microbial Communities Track Seasonal Variation in Arctic Lagoons

Creator:: Baker, Kristina D.
Abstract:: The lagoons spanning Alaska’s Beaufort Sea coast provide a unique habitat for arctic wildlife. These lagoons and the food webs they support face extreme seasonality with nine months of ice cover followed by a spring thaw that pulses a large amount of freshwater and nutrients into the lagoons. Bacteria link...
