Development of an Improved Proteogenomics Solution to Identify Comprehensive Catalogues of Novel Small Proteins in Prokaryotes
… that may provide new insights into P. stutzeri biology with further experimental analysis. Ribosome profiling detects actively translated mRNAs, providing a more sensitive prediction of new genes but with a higher potential for false positives compared to proteogenomics. As iPtgxDBs attempt to …

Aspects of modelling variability of single cell lag time for Cronobacter spp. after exposure to sublethal heat treatment in normal and stressful environments
The growth profiles of five strains of Cronobacter spp. at low temperature (4 oC to 8 oC) and their thermal resistance to mild heat treatment (48 oC to 50 oC) were investigated with a view to developing a model to predict lag times of individual cells, using a strain with a relatively high …

Effects of environmental and physiological stress on the functionality of probiotic microorganisms
The aim of this project was to examine whether exposure to environmental and physiological stress conditions could affect some functional properties for the selection of probiotic microorganisms. The study was focused on two commercial strains of Bifidobacterium animalis ssp. lactis and two …

Virus in sewage, polluted water and molluscan shellfish: a critical assessment of coliphage as a possible indicator organism
This thesis begins with a comprehensive review of bacterial indicator systems and. by drawing on published material related to the transmission of enteric viral disease in the marine environment shows that bacterial indicators are inadequate for assessing risks from viruses. Literature in respect …

Characterization of lactic acid bacteria from Nono, a Nigerian naturally fermented milk product
The aim of this research was to enumerate, isolate, identify and characterize lactic acid bacteria (LAB) from Nono, a Nigerian naturally fermented cow milk product for the selection of multifunctional starter cultures to develop a controlled fermentation process for Nono production. This study …

Genetic and functional investigation of sequence variation associated with the related phenotypes: birth weight, obesity, and type 2 diabetes (T2D)
… methods (Sequenom iPLEX and Life Technologies TaqMan) were used to genotype specific polymorphisms in the genes HHEX-IDE, ADCY5 and FTO, while molecular cloning and computer modelling techniques were used to investigate the variants in LEPR. Results: Significant associations …

Biochemical and physiological analysis of microvesicle subtypes
The research presented in this thesis encompasses a detailed biophysical and biochemical analysis of extracellular vesicles: in particular microvesicles (MVs). The characterisation utilised novel applications of existing protocols, demonstrated for the first time within this thesis, resulting in an …

Biosemiotics as systems theory: an investigation into biosemiotics as the grounding for a new form of cultural analysis
This thesis examines the relation of systems theory to biosemiotics. To this end, it considers the claim that biosemiotics is an uneven development of systems theory. To do this, this thesis explores theories of 'modelling' and 'information' in biosemiotics from the enhanced point of view of …

Climate change, trade unions and the promise of climate solidarity in the UK, 1997-2010
Contemporary climate change politics, dominated by neoliberal and ecological modernisation framings, has reached an impasse. This thesis investigates whether a Marxist critique focused on trade unions might offer an alternative approach. It critically analyses the social science literature on …

Probiotic characterization of Bifidobacterium spp. isolated from commercial fermented milk in the UK
… from the UK market throughout their shelf- life and carry out in vitro studies on some of the probiotic criteria and potential functional properties of the isolates including resistance to stomach-intestine conditions, antimicrobial activities, antibiotic resistance/susceptibility, …
