Virtually all PURPAN\u2019s research professors are involved in research, development and consulting <\/strong>activities, using their skills to meet the demands of professionals in France and abroad.<\/p>\n\n\n\n

In association with the best research organizations<\/a><\/strong> (INRAE, CNRS, etc.) and drawing on the school\u2019s research platforms<\/a>, they aim to meet the demands of companies, establish lasting research partnerships, set up thesis programs, and explore emerging fields.<\/p>\n\n\n\n

This research is carried out mainly within the Research Units: Eight of these are Joint Research Units<\/strong> (UMR) bringing together researchers from different organizations, including PURPAN, and one is an Internal Research Unit<\/strong> (UPR), with only researchers from PURPAN. <\/p>\n\n\n\n

UPR – Plant Physiology, Pathology and Genetics (PPGV)<\/h2>\n\n\n\n

This Internal Research Unit (UPR) is developing research into understanding pathosystems and plant defense mechanisms<\/strong> and studying the accumulation dynamics of agro-molecules of interest<\/strong>. <\/p>\n\n\n\n

UMR – AGroecology – Innovations – TeRritories (AGIR)<\/h2>\n\n\n\n

This UMR works on the interactions between socio-technical, socio-ecological and agroecological systems in order to analyze agrosystem transitions and design innovative agroecological systems<\/strong>.<\/p>\n\n\n\n

To achieve this, it brings together researchers and research professors in biotechnology and human and social sciences.<\/p>\n\n\n\n

The AGIR JRU sees transition as the need to leave a situation that is deemed untenable. For agriculture, it is motivated by the undesirable effects on farmers\u2019 income and isolation, the environment, territorial inequalities, the health of consumers and workers, animal welfare, etc.<\/p>\n\n\n\n

EA – Agri-Food & Environmental Biotechnologies Lab  <\/h2>\n\n\n\n

The Agri-Food & Environmental Biotechnologies Lab (LBAE) focuses on the study of complex microbial systems (CMS) of biotechnological interest in the environmental field, in particular to optimize biological purification processes and recycle residual carbon (water, waste).<\/p>\n\n\n\n

In a context of sustainable development and global change, organic effluent and waste can be treated and\/or recycled in processes that generally involve biological treatment, whether aerobic (activated sludge, aerobic granules, composting, etc.) or anaerobic (methanization). These biological treatments are made possible by the presence of complex microbial systems, i.e., aggregates mainly made up of cells and ExoPolymeric Substances (EPS) such as proteins, sugars or nucleic acids.<\/p>\n\n\n\n

The laboratory\u2019s work aims to:
–    Understand and describe EPS secretion from model aggregates or pure strains<\/strong> (heterotrophic bacteria, autotrophic organisms) as a function of nutrient conditions (mainly C\/N ratio) or the presence of micropollutants (trace metals, carbon nanoparticles);
–    Understand the biological mechanisms involved in this secretion, using molecular approaches<\/strong> (molecular biology and proteomics) to orientate metabolisms towards the production of EPS enabling the recycling of residual carbon (wastewater, biowaste). <\/p>\n\n\n\n

UMR – Genetics, Physiology and Livestock Systems (GenPhySE)<\/h2>\n\n\n\n

Created on January 1, 2014, the Genetics, Physiology and Livestock Systems (GenPhySE) Joint Research Unit constitutes a major center of expertise in animal genetics, integrative biology and, more generally, animal sciences.<\/strong><\/p>\n\n\n\n

It aims to develop animal production systems through genetic, nutritional and husbandry innovations, with a view to sustainable production. Its main activities focus on:<\/p>\n\n\n\n
