      ARTÍCULO PUBLICADO EN REVISTA EXTERNA. Bacillus licheniformis (BL ) strains are used for industrial production of exoenzymes, antibiotics and secondary metabolites, and also serve as probiotics. Some strains sequester heavy metals, promoting plant growth or inducing plant systemic resistance against stresses. However, investigations on the biological functions and applicability of carotenoids produced by BL had been less studied. In this study, the carotenoid pro!le produced by BL Rt4M10 was characterised during the accumulation period of culture and in response to diphenylamine (DPA ), inhibitor ...
    • Effects on chlorophyll and carotenoid contents in different grape varieties (Vitis vinifera L.) after nitrogen and elicitor foliar applications to the vineyard

      ARTÍCULO PUBLICADO EN REVISTA EXTERNA. Photosynthetic pigments, including carotenoids are important secondary metabolites, which play a key role in photosynthesis. There is little information about the effects of nitrogen and elicitor applications on chlorophyll and carotenoid concentrations in grapes. The aim of this work was therefore to study the effects of the foliar application of nitrogen sources and elicitors to Tempranillo, Garnacha and Graciano (Vitis vinifera L.) grapevines on chlorophyll and carotenoid contents. The results showed that β-carotene and lutein were the most ...
