The culture supernatant of E. durans LAB18s exhibited high ability to scavenge the radical ABTSþ, whereas the sample of
intracellular extract showed weak antioxidant activity, with an inhibitory percentage of 9.4%. For DPPH method, the analysis conducted with culture supernatant showed high antioxidant activity (EC50 ¼ 3.6) compared to the control (EC50 ¼ 9.77). The intracellular extract of E. durans LAB18s showed low antioxidant activity (EC50 ¼ 8.79) compared to the control (EC50 ¼ 9.48).
