Résumé du contexte et des objectifs généraux du projet

Food production systems are facing many challenges like climate change and demographic growth. There is an urgent necessity for more sustainable approaches to transform food production systems, by advancing scientific research that contribute to climate resilience, biodiversity preservation, soil restoration and healthier diets, in line with the European Green Deal priorities and Farm2Fork strategy.
Wheat, a central crop with high protein and energy content and with low growing requirements, benefits from soil and plant microbial communities for (1) restoring soils and protecting the crops and wheat-derived products against pathogens; (2) regulating plant metabolisms and overall crop quality; and (3) improving the production of nutritional and healthy food and feed products. However, the current data about wheat microbiomes is scarce. The WHEATBIOME project is advancing the knowledge on the wheat microbiome’s role in sustainable development through cutting-edge research and collaboration between academia, industry, food system actors and governmental authorities. The project is exploring microbiomes in wheat production systems from soil to plate aiming to:
• Understand the impact of biotic/abiotic factors on wheat microbiomes;
• Evaluate the impact of soil-plant microbiome interactions on wheat metabolism and nutritional quality to further develop a new decision support system (DSS) that will include sustainable farming practices for resilient and nutritious wheat crops;
• Discover new wheat fermentative microbiomes for development of novel fermented foods and feeds.
• Study microbial fermentations in food/feed quality and reduce food waste by recirculating wheat byproducts.
• Assess the impact of wheat nutrients and microbiome (prebiotics, probiotics, bioactive compounds, immunogenic proteins, etc.) on human/animal microbiota and health.
• Assess the perception of food system actors and citizens about microbiomes within food systems.
Overall, WHEATBIOME’s research and development actions, combined with a multi-actor approach, will boost the change in food systems towards sustainability.

Travail effectué depuis le début du projet jusqu’à la fin de la période considérée dans le rapport et principaux résultats atteints jusqu’à présent

The project aims to elucidate the role of soil and plant microorganisms in enhancing wheat sustainability, nutritional quality, immunogenicity, and the composition of bioactive compounds in wheat plants. Two distinct case studies were implemented to examine the impact of agricultural practices (both ecological and conventional, including irrigation and non-irrigation conditions) as well as edaphoclimatic factors and wheat genetic varieties on soil and plant microbiota. The objective is to correlate these microbial communities and the soil-plant interactions with the nutritional, immunogenic, and bioactive composition of wheat, develop a bioinformatic tool to help select the wheat variety according to the proper edaphoclimatic conditions for specific nutritional outcome and select the microbes with best performance to design microbial-based food. Wheat samples from 2023 campaign were collected, and the characterization of soil and plant microbiota for both case studies have been completed. Additionally, the analysis of the nutritional composition concerning the impact of agricultural practices has been finalized. The fully assessment of the influence of edaphoclimatic and genetic conditions on nutritional composition is still ongoing. The quantification of total immunogenic proteins has been accomplished for both case studies, and the characterization of bioactive compounds is currently in progress. Twenty fermented food prototypes (including bevereges, yogurt-like and cheese-like products) are intended to be obtained by selecting the best microbial performance according to nutritional composition, bioactive compounds and food immunogenicity. To date, seven wheat-based fermented beverages, two yogurt-type products, and one cheese-type product were designed. The bioactive compounds and gluten quantification was already performed on the beverages while the additional food is being currently analysed. In addition, WHEATBIOME is working to define the methodological procedure for assessing the environmental and economic performance of its novel products. Survey questionnaires to food system actors are being implemented in Hungary, Netherlands and Spain to evaluate European food system's ability to provide healthy and sustainable food and feed, identify barriers and enablers for adopting sustainable practices at the EU level, and determine the desired characteristics of novel wheat by-product-based fermented food and feed products.

Progrès au-delà de l’état des connaissances et impact potentiel prévu (y compris l’impact socio-économique et les conséquences sociétales plus larges du projet jusqu’à présent)

The impact of various farming practices, climate change, and genetic variability on the wheat microbiome remains inadequately characterized. Understanding the combined effects of these biotic and abiotic factors on wheat crops is crucial for establishing guidelines that promote more sustainable farming practices. WHEATBIOME is investigating the interconnections between environmental conditions, climate factors, and genotype on wheat plant growth and development with two case studies in different European regions (Spain and The Netherlands). Additionally, WHEATBIOME is collecting data on the factors influencing the wheat food system, including perceptions, needs, and limitations related to microbiome use in food development, by interviewing stakeholders across three European countries.
WHEATBIOME is also contributing to the global demand for healthier and more sustainable food products by establishing protocols for developing alternative plant-based foods through fermentation, such as beverages, yogurt-like products, and cheese substitutes. Moreover, WHEATBIOME is pioneering in the identification of novel fermentative microorganisms isolated from wheat plants and soil to be used for healthier plant-based food development. WHEATBIOME is committed to developing innovative feed products that are both environmentally friendly and economically viable. The project is setting parameters for the development of feed products with enhanced nutritional profiles, achieved by fermenting wheat byproducts with selected microorganisms.
