La fermentation sombre et les piles à combustible microbiennes (MFC) sont deux technologies émergentes respectivement pour la conversion biologique de l'énergie chimique des composés organiques en hydrogène (H2) et en électricité. En raison des avantages cinétiques et thermodynamiques, la température élevée peut être la clé pour augmenter à la fois la production d'H2 de fermentation sombre et la production d'électricité dans les MFC. Par conséquent, cette thèse se concentre sur la manière dont la température influence la production biologique de H2 et d'électricité à partir d'eaux usées conten

Abstract:

Biocatalysis is a field rapidly expanding to meet a demand for green and sustainable chemical processes. As the use of enzymes for synthetic chemistry becomes more common, the construction of multistep enzyme reactions is likely to become more prominent providing excellent cost and productivity benefits. However, the design and optimisation of multistep reactions can be challenging. An enzyme toolbox of well-characterised enzyme parts is critical for the design of novel multistep reactions. Furthermore, while whole-cell biocatalysis offers an excellent platform for multistep reactions, we are

Abstract:

DNA is constantly subjected to chemical and mechanical damage. The ability to repair the lesions sustained is essential for all life. Double stranded DNA (dsDNA) breaks are especially toxic as both antiparallel strands of DNA are severed. The most high fidelity mechanism available to repair this damage is homologous recombination, a mechanism that uses homology from the sister chromatid to replace any lost information. Key proteins involved in maintaining genomic stability this way are conserved in all domains of life. One such component is the Mre11/Rad50 complex that is involved in the initi

Abstract:

This is an investigation into alcohol dehydrogenases (ADHs) from Geobacillus thermoglucosidasius. Eighteen ADHs have been studied, with seven taken for closer inspection. Characterisation was carried out to determine the industrial significance of these enzymes, starting with the substrate scope of the ADHs. The key results obtained are as follows: ADH A is the alcohol dehydrogenase domain of the bifunctional ADHE enzyme (Extance, 2012; Extance et al., 2013). It has been determined that the substrate scope, whilst restricted to linear aliphatic aldehydes, extends at least to dodecanal. Also, w

The nucleotide sequence of cnjB, a conjugation specific gene of Tetrahymena thermophila, has been determined. The gene encodes a putative polypeptide (CnjB) of 1748 amino acids with a calculated molecular weight of 200 kilodaltons and a pI of 7.9. Four transcription start sites were mapped. The gene has only one genomic copy and is not conserved in yeast (as determined by cross-hybridization experiments with yeast DNA). Analysis of the 13 introns in cnjB, accompanied by 15 other T. thermophila intron sequences, shows that they resemble the nuclear pre-mRNA introns of other eukaryotes.<br>The c

The cnjA message is initiated from four transcription start sites, one minor and three major, and encodes a putative protein (CnjA) of 779 amino acids. The protein has a calculated molecular weight of 89.5 kDa and is mainly hydrophilic with an estimated pI of 9.3. CnjA was found to share no sequence similarities with any known protein to

Abstract:

A reverse transcription reaction allows the production of complementary DNA (cDNA) using an RNA template and relies on polymerases displaying reverse transcriptase (RT) activity. This process, with major applications in both research and in medical diagnostics, is often limited by the nature of the RTs available. RNA secondary structure can prove problematic where mesophilic retroviral RTs are used while the alternative approach, using thermophilic DNA polymerases with RT activity, often results in error-prone cDNA production. <br /> This project recognised the need to study other possible sou

There is a requirement in the European Union to divert organic wastes from landfill because of the risk of methane emissions. One alternative is anaerobic digestion of organic wastes, such as food waste, to stabilise them whilst at the same time recovering the energy from them. One problem with this approach is that the high nitrogen content of food waste may lead to ammonia inhibition. A solution to this has been found for mesophilic digestion but had not been attempted in thermophilic digestion where ammonia toxicity is known to be more acute.

The nucleotide sequence of the pulA gene was shown to be 2478 basepairs (bp) in length, coding for a protein of 96 kDa.
