Early-maturing annual legumes: an option for cover cropping in rainfed olive orchards
M. Ângelo Rodrigues,Paulo Dimande,Ermelinda Pereira,Isabel Q. Ferreira,Sara Freitas,Carlos Correia,José Moutinho-Pereira,Margarida Arrobas +7 more
TL;DR: The results showed intense biological activity in the 0–10 cm soil layer of the treatments producing more biomass and the N nutritional status of the olive trees was significantly higher in Legs than in natural vegetation plots even when 60 kg N ha−1 year−1 was applied.
Journal ArticleDOI
Probiotic potential of indigenous yeasts isolated during the fermentation of table olives from Northeast of Portugal
Tatiane Cristina Gonçalves de Oliveira,Elsa Ramalhosa,Luís Nunes,José Alberto Pereira,Eliane Colla,Ermelinda Pereira +5 more
TL;DR: Results suggest that some yeast strains involved in the fermentation of table olives have probiotic potential, and these yeast strains could be used as culture starters for the development of new functional products.
