Project description:
The FAIROmics initiative, an interdisciplinary research programme, brings together universities, research centres and private companies to enable the FAIRification of omics data and databases interoperability. Furthermore, knowledge graphs for data-driven decision-making will be developed to rationally design microbial communities that provide plant-based fermented foods with desirable characteristics in the context of open science and its regulations. The FAIROmics training programme aims to develop doctoral candidates’ skills at the interface between artificial intelligence, life sciences, humanities, and social sciences.
Scientific context:
Plant-based dairy and meat alternatives have grown in popularity in recent years for various reasons, including sustainability and health benefits, as well as lifestyle trends and dietary restrictions. However, plant-based food products can be nutritionally unbalanced, and their flavour profiles may limit their acceptance by consumers. Microorganisms have been used in making food products for millennia. However, the diversity of microbial communities driving plant-based fermentations, as well as their key genetic and phenotypic traits and potential synergies among community members, remain poorly characterised. Many data exist, but they are spread across scientific literature or, in the best case, in different databases. Data are not always reusable because they are difficult to find and access and because databases are not systematically interoperable.
Objectives:
We are looking for a Doctoral Candidate (DC) to join our project at multiple sites in Europe with a master’s degree in (Food) Microbiology / Bioinformatics / Biotechnology who is interested in new concepts for developing safe innovative plant-based fermented foods based on genome mining of starter bacteria.
The main objective of this research project is to rationally design mixed bacterial cultures to ferment plant protein-based ingredients with desirable outcomes. This will be based on predictions derived from available data sets on individual lactic acid bacteria (LAB) strains (with available sequenced genomes) and favourable fermentation outcomes upon growth on different plant-based substrates. Strain capabilities relevant to the preservation and safety of plant-based products will be determined. The performance of mixed cultures to ferment plant-protein-based ingredients regarding the formation of favourable flavour compounds, removal of unwanted chemical contaminants (e.g. off-flavours, mycotoxins), and acid formation and preservation effect (suppressing the growth of spoilers and pathogens) will be verified. Linking of functional properties of strains and genomic traits with fermentation outcomes will support the design of novel fermented foods.
The project is expected to generate a model to predict outcomes of different plant protein-based fermentations using mixed cultures of lactic acid bacteria with respect to flavour formation, removal of unwanted compounds, and preservation capacity. This allows for steering relevant fermentation outcomes based on key gene functions and fermentative capacity of LAB strains on different plant-based substrates.
Location and planned secondments:
The position is based at NIZO in The Netherlands with close collaboration with Wageningen University.
Secondments will take place:
National and Kapodistrian University of Athens, 8 months: metabolomics analyses of metabolites in plant matrices upon fermentation.
University of Reading, 3 months: physiological evaluation of key gene expression in selected lactic acid bacteria.

Within NIZO, comprehensive knowledge is available on fermentation characteristics of starter culture strains when grown on dairy and plant substrates in relation to development of flavour and controlling food safety and quality. The lead supervisor is Principal Scientist Dr. Marjon Wells-Bennik. She has a background in food microbiology (including functional genomics expertise) and is a visiting scientist at Wageningen University. She initiated various consortium projects with multiple academic and industrial stakeholders, including a recent project on “Microbial contaminants in plant-based protein ingredients”. Co-supervisors at NIZO are Dr. Eric Hester (senior bioinformatician/data scientist) and Dr. Herwig Bachmann (extensive expertise in fermentation, dairy and dairy-alternative technology).
At Wageningen University (WU) supervision will be provided by Prof. Dr. M.H. Zwietering who is the Head of the Food Microbiology group (FHM) and has a background in modelling. His group investigates aspects of food safety, food spoilage and fermentation.
At the University of Athens (Department of Chemistry), supervision is provided by Associate Professor Dr. Vasilis Valdramidis and Assistant Professor Dr. Marilena Dasenaki. The department uses cutting-edge mass spectrometric techniques and advanced chemometric tools to study food metabalomics.
At the University of Reading (UREAD), supervision is provided by Associate Professor Dr. Kimon A. G. Karatzas. He heads the Food Microbiology group in the Department of Food & Nutritional Sciences, University of Reading. He has a longstanding experience in microbial physiology of stress and molecular biology and more than 22 years of experience in food fermentations.
The student will benefit from the knowledge that has been built up in the domain of this project and be supervised by experienced staff in the field of food microbiology, fermentation, and bioinformatics at NIZO and WUR. In addition, the student will greatly benefit from the chemical analytical and predictive modelling capabilities at NKUA and access to molecular biology expertise at UREAD. Moreover, collaboration will be set up on semantic data mining at the start of the project, and the use of artificial intelligence to train and improve models for rational predictions of favourable fermentation outcomes.
