The aim of this work was to (i) determine the chemical composition of the essential oils of three spices widely cultivated in Spain from organic growth: , , and ; (ii) determine the total phenolic content; (iii) determine the antioxidant activity of the essentials oils by means of three different antioxidant tests and (iv) determine the effectiveness of these essentials oils on the inhibition of CECT 910 and CECT 844. There is a great variability in the chemical composition of the essential oils. Parsley had the highest phenolic content. Overall, parsley presented the best antioxidant profile, given its highest % of inhibition of DPPH radical (64.28%) and FRAP (0.93 mmol/L Trolox), but had a pro-oxidative behavior by TBARS. Lavender essential oil showed the highest antibacterial activity against (>13 mm of inhibition at 20-40 μL oil in the discs), followed by parsley with an inhibition zone of 10 mm (when more than 5 μL oil in the discs), and fennel 10 mm (when more than 40 μL oil in the discs). was not inhibited by the tested essential oils.

is considered one of the main fungi responsible for black and sour rot in grapes, as well as the production of the carcinogenic mycotoxin ochratoxin A. The global regulatory methyltransferase protein controls the production of various secondary metabolites in species, as well as influences sexual and asexual reproduction and morphology. The goal of this study was to investigate the role of the regulatory gene in physiology, virulence, and ochratoxin A (OTA) production by deleting this gene from the genome of a wild-type strain.
