Evaluation of Raw Cheese as a Novel Source of Biofertilizer with a High Level of Biosecurity for Blueberry

Today’s agriculture requires the search for new and modern tools in order to improve expand use of its crops increase their sustainability. The plant growth-promoting PGP bacteria (PGPB) is target much research seems be an ideal strategy as long strains are properly selected this purpose. Among bacteria, lactic acid (LAB) considered a suitable alternative due high biosafety mechanisms promoting growth. In view this, work we decided isolate LAB with capacity from raw milk cheese PDO “Serra da Estrela”. A total 88 diversity remarkable control food-borne pathogenic microorganisms were isolated. addition, most them showed excellent capacities phosphate solubilization production indole-3-acetic siderophores. Subsequently, also studied inoculation blueberry seedlings. isolates, QSE20, QSE62 QSE79 ability efficiently colonize rhizosphere plant, improving root development increasing number secondary roots.
