Diameter of the Inhibition Zone (DIZ) of the phenolic compounds obtained from S1 and S2 berries, against two fungal pathogenic strain: Candida albicans and Aspergillus niger, together with positive control fluconazole (FCZ) with 25 μg/disc). NO: no action (DIZ < 7 mm); R: resistant (DIZ7-12 mm); I: intermediate (DIZ between 12–18 mm); S: susceptible (S) (DIZ > 18 mm); S1: berries harvested from Romania; S2: berries harvested from Russia. The results are expressed as mean ± percentage deviation, n = 3. Although antimicrobial activities of obtained polyphenols from berries were generally much lower than the antimicrobial effects of antibiotics, some of them demonstrate significant antibacterial effects during studies in-vitro, comparable to the effect of an antibiotic at a low dose.
