Abstract:
The recent surge in biodiesel production has resulted in a huge surplus of crude glycerol, a by-product of the process to the level of 10% by weight. This is turn has caused the price of glycerol to fall dramatically, and there are now few economically viable channels for using this resource: waste glycerol is usually combusted. Therefore, much interest has arisen in the possibility of making use of glycerol with biotechnology, as this would not only be a more efficient use of resources but also make biodiesel itself more commercially viable.

Abstract:
Anaerobic bacteria typically degrade many types of aromatic monomers through conversion to benzoyl-CoA which is further degraded by ring reduction, ring cleavage and β-oxidation reactions. Rhodopseudomonas palustris has the ability to grow on different side-chain length aromatic compounds ranging from 3-phenylpropanoic acid to 8-phenyloctanoic acid. A β-oxidation or non β-oxidation metabolic pathway could be responsible for degradation of these compounds. To study the pathways and genes involved, a full cellular proteome analysis using mass spectrometry was carried out and the expression patte

Moreover, a short description of all ways to dissipate the excess of energy by photosy

As Hydrogen has high energy density (142 MJ/Kg), a sustainable platform of hydrogen utilization can be established if it can be generated sustainably and used safely, as well as being stored and transported efficiently. There are various ways to produce hydrogen, among which photosynthetic hydrogen production by purple non-sufur photosynthetic bacteria (PNSB) is one of the favorable methods for biohydrogen production

碩士<br>國立臺灣大學<br>生化科技學系<br>104<br>Rhodopseudomonas palustris NTUIOB-PS3, a phototrophic purple non-sulfur bacterium, was originally isolated from paddy field in Taiwan. It can not only improve plant growth, but also reduce the nitrate accumulation in plants. The aim of this study was to investigate the mechanism of its plant growth promotion effect. We would like to elucidate the effects of rhizosphere bacteria on plant physiology through evaluating the nitrogen uptake efficiency, activity of nitrogen assimilation associative enzymes, gene expression of nitrate transporters, and CO2 assimilatio

Abstract:
The present work illustrates the structural and biochemical characterization of two diverse proteins, BadI and MenD from Rhodopseudomonas palustris and Staphylococcus aureus, respectively. BadI or 2-ketocyclohexanecarboxyl-CoA is one of the key enzymes involved in the anaerobic degradation of aromatic compounds. The degradation of aromatic compounds is a vital process for the maintenance of the biogeochemical carbon cycle and bioremediation of xenobiotic compounds, which if present at higher concentrations can cause potential hazards to humans. Due to the relatively inert nature of aromatic co

This thesis is dealing with my work in the field of microbial electrochemistry of relevant microbial strains applied to microbial electrolytic cells. It consists of two main topics: the electrochemical characterization of the novel CO2 reduction reaction in the electroactive model bacterium Shewanella oneidensis MR-1 and the electrochemical characterization of strain 42OL of the Purple Non Sulfur Bacteria Rhodopseudomonas palustris. During the time I was in Japan at the University of Tokyo, I explored the possibility of carbon fixation by Shewanella oneidensis MR-1 model microbe for anodic ext

However, hydrogen can be an alternative and sustainable energy source due to the properties of clean and high energy yield（122 kJ/g）, which is an environmentally friendly technology in the future. Biohydrogen, comparing with the other technologies of hydrogen production, has the advantages of organic waste recycling and cost- effectiveness. Therefore, the aim of this study focuses on the combin
