Abstract from Microbiotec’25, Ponta Delgada, Portugal.58108976-19ba-413e-b839-9d5816b2af45http://hdl.handle.net/10400.14/56761Background: Wine industry generates by-products including grape stalks and washing sludge which are often burned, thus becoming an economically and environmentally unsustainable practice. A promising alternative is to reuse these wastes through composting. Isolating plant growth-promoting bacteria (PGPB) from composted wine residues represents a valuable strategy, as both PGPB and compost may enhance plant growth and soil health. This study aimed to isolate and identify bacteria from different composting piles and assess their ability to produce plant growth-promoting (PGP) substances.engconference object
