The purpose of the role is to characterise food grade bacteria with antimicrobial activity against specific spoilage and pathogenic microorganisms. This study will focus on the exploration of antimicrobial peptides as viable alternatives to current food preservation methods, with the aim to isolate and characterise organisms producing antimicrobials which have applications for improvements to food.

Background to this Project Microbial secondary metabolites are highly desirable in the food industry and contribute not just to product quality and flavour but also to shelf-life and safety. In this respect, antimicrobial-producing Lactic Acid Bacteria (LAB) have been shown to enhance food safety and extend shelf-life for a variety of food applications.

Our group within APC Microbiome Ireland have extensive experience of large scale screening programmes for antimicrobials which have led to the discovery of a variety of bacteriocins including Lacticin 3147, Bactifensin, Thuricin, and more recently Nisin J and Actifensin.  The purpose of the project is to isolate food grade bacteria with antimicrobial activity against specific spoilage and pathogenic microorganisms as viable alternatives to current food preservation methods.

Background to the Teagasc Post Doctoral Programme 

This is a research focused training role, the primary purpose of which is to provide early career scientists with the opportunity to develop their research skills and competencies. The PD Fellow will, while working in conjunction with senior research staff, gain insight and experience into a variety of areas including the processes of project and budgetary management, the development of active collaboration with relevant national and international research communities, the development of communication and presentation skills and possible experience in the mentorship of students.

The PD Fellow will conduct a specified programme of research, supported by a modular training programme, which will include modules of relevance for the development of specific knowledge and research skills, professionalism and communication skills, leadership and management skills, and overall career development.

Modules will be conducted under the supervision and direction of the (Project Leader) or other designated manager in conjunction with the Head of Department.

The Teagasc post-doctoral programme provides training and development opportunities for early career scientists that enhances their experience of learning and equips them with the necessary skills for the next stage of their chosen career in research.
