Biotechnological utilisation of Nephrops shell waste
Shellfish processing results in the disposal of large quantities of waste to landfill sites. This project sought to deal with the issue of the processing of marine crustacean waste, specifically that of the prawn, Nephrops norvegicus. The exoskeleton of Nephrops norvegicus contains chitin, …

Bacterial lipoproteins: sorting mechanisms and biotechnological applications
The mechanism responsible for lipoprotein sorting is conserved among bacterial species. However, the final destination of lipoproteins may vary among species. In some species lipoproteins are surface-exposed while in others they are associated to the outer membrane but facing the periplasm. To …

The Biotechnological Applications of an Insect-Specific Alphavirus
The coupling of viral and arthropod host diversity with evolving methods of virus discovery has resulted in the identification and classification of a growing number of novel insect-specific viruses (ISVs). These viruses appear to be evolutionarily related to many human pathogens but have either …

Isolation and Characterisation of Yeasts with Biotechnological Properties
The primary aim of this research was to identify and characterise novel non-Saccharomyces species from a vineyard and assess their potential use as starter cultures, either as an alternative or complement to Saccharomyces cerevisiae. The first step towards this aim was to access the vast potential …

A Theoretical Approach to Guiding Biotechnological Improvement of Crop Photosynthetic Efficiency
This thesis aims to use computational modeling approaches to advance identifying targets for higher photosynthetic efficiency. Two approaches have been identified that can substantially increase daily canopy photosynthetic CO2 uptake rate (Ac). Replacement of current C3 crop Rubisco with foreign …

DEVELOPMENT OF NOVEL BIOTECHNOLOGICAL APPROACHES FOR ACCELERATING GENETIC GAIN IN THE BOVINE
Modern livestock production is increasingly challenged to improve reproductive efficiency while maintaining sustainability and animal welfare standards. Accelerating genetic gain in cattle (Bos taurus) is essential for breeding animals that are more resilient to climate change, more resistant to …

Biohydrogen as a Fuel: Understanding and Engineering Hydrogenase Enzymes for Biotechnological Applications
Molecular hydrogen (H2) is seen as an ideal replacement for fossil fuels; however the current methods of its synthesis are unsustainable and environmentally damaging. Research is therefore needed to devise new, more suitable modes of H2 derivation. Biohydrogen – i.e. H2 derived from cellular …

A statistical framework for extraction of structured knowledge from biological/biotechnological systems
… efforts to understand complex biological/biotechnological systems, a significant amount of knowledge has still remained unraveled. However, recent advances in high throughput technologies have offered new opportunities to understand these complex systems by providing us with huge amounts …

Characterization and engineering of sugar transporters in the yeast Kluyveromyces marxianus for biotechnological applications
Sustainable and efficient use of lignocellulosic hydrolysates in yeast-based biorefineries requires the simultaneous consumption of all the sugars present in this raw material, hexoses and pentoses. This represents a key bottleneck because of the low number of specific pentose transporters …
