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 ... -
Ecological dependencies and the illusion of cooperation in microbial communities
(2024)Ecological dependencies - where organisms rely on other organisms for survival - are a ubiquitous feature of life on earth. Multicellular hosts rely on symbionts to provide essential vitamins and amino acids. Legume plants ... -
Community composition drives siderophore dynamics in multispecies bacterial communities.
(2023)Background Intraspecific public goods are commonly shared within microbial populations, where the benefits of public goods are largely limited to closely related conspecifics. One example is the production of iron-scave ... -
Ecological selection of siderophore-producing microbial taxa in response to heavy metal contamination
(2018)Some microbial public goods can provide both individual and community-wide benefits, and are open to exploitation by non-producing species. One such example is the production of metaldetoxifying siderophores. Here, we ... -
No effect of intraspecific relatedness on public goods cooperation in a complex community
(2018)Many organisms—notably microbes—are embedded within complex communities where cooperative behaviors in the form of excreted public goods can benefit other species. Under such circumstances, intraspecific interactions are ... -
Transposable temperate phages promote the evolution of divergent social strategies in Pseudomonas aeruginosa populations
(2019)Transposable temperate phages randomly insert into bacterial genomes, providing increased supply and altered spectra of mutations available to selection, thus opening alternative evolutionary trajectories. Transposable ... -
Cultivating antimicrobial resistance: how intensive agriculture ploughs the way for antibiotic resistance
(2023)Antimicrobial resistance (AMR) is a growing threat to public health, global food security and animal welfare. Despite efforts in antibiotic stewardship, AMR continues to rise worldwide. Anthropogenic activities, particularly ... -
Development of liquid culture media mimicking the conditions of sinuses and lungs in cystic fibrosis and health
(2022)The respiratory tract is a compartmentalised and heterogenous environment. The nasopharynx and sinuses of the upper airways have distinct properties from the lungs and these differences may shape bacterial adaptation ... -
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. ... -

Aneuploidy influences the gene expression profiles in Saccharomyces pastorianus group I and II strains during fermentation
(2022)The lager yeasts, Saccharomyces pastorianus, are hybrids of Saccharomyces cerevisiae and Saccharomyces eubayanus and are divided into two broad groups, Group I and II. The two groups evolved from at least one common ... -
Packing a punch: Understanding how flavours are produced in lager fermentations
(2021)Beer is one of the most popular beverages in the world and it has an irreplaceable place in culture. Although invented later than ale, lager beers dominate the current market. Many factors relating to the appearance (colour, ... -
Population genomics of the pathogenic yeast Candida tropicalis identifies hybrid isolates in environmental samples
(2021)Candida tropicalis is a human pathogen that primarily infects the immunocompromised. Whereas the genome of one isolate, C. tropicalis MYA-3404, was originally sequenced in 2009, there have been no large-scale, multi-isolate ...
