¹EPS concentration in culture supernatants was determined after ethanol precipitation (1:3) by neutral sugars quantification by the phenol-sulfuric method

²Riboflavin fluorescence was measured in culture supernatants and its concentration was inferred from a riboflavin calibration curve

^a–eMeans with different letters differed significantly (p value ≤ 0.05)
