Third Training School
PurpleFood: PPB in sustainable nutritional and functional foods
14-16 May 2025
Antwerp – Belgium
The funding application has now closed, but registration remains open until April 15.
COST Action
COST Action CA21146
COST Action CA21146 is a four-year networking action that aims at creating a European network to share information, facilitating technology and knowledge transfer between the academic and industrial sectors, related to Purple Photosynthetic Bacteria (PPB) applications for resource recovery from organic waste sources. Resource recovery includes wastewater or organic waste, open or closed environments, in single or chain processes.
The network associates fundamental-focused and applied research groups, improving lab-scale technology optimization through mechanistic modeling. It benefits the technology transfer from applied-research groups to industry, considerably improving process design. PURPLEGAIN also aims to create a database for techno-economic, social and environmental impacts studies, which facilitates the marketability of both the PPB-based technologies and the products to extract. Some focused products are polyhydroxyalkanoates, single-cell proteins, biomass for energy, biomass as fertilizer, biohydrogen, carotenoids, terpenoids, organic acids, coenzyme Q10, and 5-aminolevulinic acid.
COST
COST is an intergovernmental framework for European Cooperation in Science and Technology established to initiate networking and coordination of nationally funded research activities on a European level. It facilitates bringing good scientists together under light strategic guidance based on networks, called COST Actions, centred around research projects in fields that are of interest to COST countries and cooperating countries.
