eng	Effect of clove and thyme essential oils on growth inhibition and biofilm formation of Arcobacter spp.	This study evaluates the antibacterial activity of clove and thyme essential oils against Arcobacter spp., Gram-negative bacteria capable of forming resistant biofilms. Antimicrobial effects were assessed using the volatilization method, growth monitoring in an RTS-8 bioreactor, and biofilm assays. Both oils showed antimicrobial activity, with effective concentrations ranging from 32–1024 µg/mL in liquid and 512–1024 µg/mL in vapor. Growth-curve analyses supported these findings, and inhibition zones reached 37.3–47.5 mm for thyme and 25.0–38.0 mm for clove. Higher oil concentrations (64–1024 µg/mL) reduced biofilm formation, while lower levels (1–32 µg/mL) tended to enhance it. Overall, clove and thyme oils appear to be promising antimicrobial agents against potentially pathogenic Arcobacter.	Arcobacter; biofilm; clove; essential oil; thyme
