| dc.description.abstract | Introduction and aims: In 2024, Portugal ranked among the world’s top ten wine producers (OIV, 2025). This industry generates several by-products including grape stalks and sludge from the water used to wash winemaking machinery. Both residues are undervalued, as they are often burned, a practice that is economically and environmentally unsustainable. A promising alternative is to reuse these wastes through composting. This controlled microbial driven process enriches the organic fraction of these residues, transforming them into a stable compost comparable to soil humus. Moreover, 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 therefore aimed to isolate, characterize, and identify bacteria from different composting piles and assess their ability to produce plant growth-promoting (PGP) substances. Conclusions: The composting of wine-industry sludge and wine stalks facilitated the isolation and characterization of diverse bacterial strains possessing multiple plant growth- promoting traits. Composting pile 3, composed of equal proportions of grape stalks and sludge, allowed the characterization and identification of a higher diversity of isolates, corresponding to five distinct bacterial genera. | eng |
