The level of FF tolerance in S. passalidarum CMUWF1−2 incubated for 48 h (a) and 72 h (b) at 30 °C. Various cell concentrations of CMUWF1−2 were spotted on YPD agar supplemented with 0.0, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5 and 4.0 g/l FF. The cell suspension, containing approximately l × 107 cells/ml was 10-fold serially diluted and spotted onto agar plates. Data were reproduced by two independent experiments
