Investigating the potential to source novel postbiotics with anti-microbial or immune-modulatory activity from distillery waste
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Microbiology, 2024)The purpose of this project is to find a novel source for antimicrobial and immunomodulatory compounds. Here we investigate the antimicrobial and immunomodulatory potential of postbiotics sourced from whisky distillation. ... -
Preventing protein-dependent biofilm formation in Staphylococcus aureus by targeting the serine aspartate repeat protein C and fibronectin binding proteins
(Trinity College (Dublin, Ireland). Department of Microbiology, 2017)Staphylococcus aureus is a leading cause of biofilm infections on indwelling medical devices. S. aureus biofilm infections are intrinsically difficult to treat. They are recalcitrant to conventional antibiotics and resistant ... -
Understanding the Role of Host Factors in the Modulation of Virulence Factors of Staphylococcus aureus.
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Microbiology, 2023)Staphylococcus aureus is adept at colonising and infecting the human host. Host factors are known to influence pathogen physiology and this thesis aimed to examine the effects of human bile and human plasmin on S. aureus. ... -
Distinct phenotypes and transcriptomes of tup1 and cyc8 mutants suggest novel roles for TUP1 and CYC8 in Saccharomyces cerevisiae
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Microbiology, 2023)The Tup1-Cyc8 (Ssn6) co-repressor complex is a regulator of gene transcription in the yeast Saccharomyces cerevisiae. This project provides insights into the distinct roles of Tup1p and Cyc8p in gene repression, identifies ... -
Investigating Tup1-Cyc8 complex function in Saccharomyces cerevisiae following the confirmation and characterization of a TUP1 conditional mutant
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Microbiology, 2023)The Tup1-Cyc8 complex is a well-defined corepressor complex found in S. cerevisiae. It is known to regulate close to 3% of all yeast genes and has orthologs reported in mammals. Its exact functioning is not well-understood. ...
