- Title: Boosting the use of PPB as innovative food and feed ingredients: From metabolism to health-promoting effects
Organizing committee: Baptiste Leroy (Working Group 1 Leader), Dr. Arpita Bose (WG1 co-Leader), Dr. Raul Muñoz Torre (Grant Awarding Coordinator), Dr. Joana Fradinho (Vice Chair), Dr. Ioanna Vasiliadou (Training Schools Coordinator), Dr. Daniel Puyol (Chair), Dr. Valérie Dormal (Purple4Life).
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 modelling. 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, biohydrogen, biomass as fertilizer, 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.

Evaluation process and result announcement
Evaluation process
The selection committee, composed of the Action Chair, the Vice Chair, the Grant Awarding coordinator, the Training Schools Coordinator and the WG1 Leaders, and the local organizers will evaluate the applications within a short time period (after the abstract submission deadline) and will inform all the applicants for their evaluation results. The successful applicants will then receive an e-mail from the grant holder (Grant Letter Notification), stating the official approval of the reimbursement, the granted budget and a payment request form which has to be completed after the completion of the Workshop.
Criteria of reimbursement
If the amount of reimbursement by all applications within a call does not exceed the available budget, the applications are handled by the selection committee. If there are more applications than funding is available, the following procedure takes place.
- A list of all applications (containing an informative summary) is distributed to all members of the selection committee in form of a table in which every evaluator can mark which applications he or she can evaluate according to their field of expertise.
- To guarantee a fair and objective evaluation, an evaluator should have no affiliation with neither the home nor the host institution of the application in question.
- All applications are evaluated by two members of the selection committee. The Grant Awarding coordinator distributes the proposals to the individual evaluators.
- The criteria given in the table below shall be applied for evaluation. The first criterion (a) is assessed by the Grant Awarding coordinator prior to the evaluation process.
| Criterion | max. points |
| a) Before any further criteria are considered | |
| Application is complete and fulfils all formal requirements | pass/no pass |
| The application will be ranked last if the applicant was granted in previous call | pass/no pass |
