摘要: The aim of this work was to assess the in vitro antimicrobial effects that wastewaters from alpeorujo oil extraction have against phytopathogenic bacteria and fungi. Alpeorujo stored for 6 months then processed extract its oil, pomace, a new liquid waste (OWSA), which characterized by content phenolic compounds. OWSA at 20% decreased bu >4 log population Erwinia spp., Pseudomonas Clavibacter spp. viable cells test tubes, whereas 50% agar medium necessary inhibit mycelial growth most It found bactericidal effect due joint action low molecular mass compounds, although neither hydroxytyrosol, glucosides, hydroxytyrosol glycol, nor glutaraldehyde-like compound individually explained bioactivity. Hence, constitutes promising natural solution fight plant
